Outreach programs/Possible projects

We are using this list of projects as a master branch for Mentorship programs such as Google Summer of Code and Outreach Program for Women. The projects listed are good for students and first time contributors but they require a good amount of work. They might also be good candidates for Individual Engagement Grants.


 * Featured project ideas usually have mentors ready for you to jump in.
 * Raw projects are interesting ideas that have been proposed but might lack definition, consensus or mentors, and therefore we can't feature them. If you're interested in one of those, wonderful! You'll need to work a bit more to improve their fundamentals.

If you are looking for smaller tasks check the Annoying little bugs. For a more generic introduction check How to contribute.



Be part of something big
We believe that knowledge should be free for every human being. We prioritize efforts that empower disadvantaged and underrepresented communities, and that help overcome barriers to participation. We believe in mass collaboration, diversity and consensus building to achieve our goals.

Wikipedia has become the fifth most-visited site in the world, used by more than 400 million people every month in more than 270 languages. We have other content projects including Wikimedia Commons, Wikidata and the most recent one, Wikivoyage. We also maintain the MediaWiki engine and a wide collection of open source software projects around it.

But there is much more we can do: stabilize infrastructure, increase participation, improve quality, increase reach, encourage innovation.

You can help to these goals in many ways. Below you have some selected ideas.

Where to start
Maybe at this point your proposal is just a vague idea and you want to get some feedback before investing much more time planning it? We know this feeling very well! Just send an email to wikitech-l (or qgil@undefinedwikimedia.org if you prefer) sharing what you have in mind. One short paragraph can be enough to get back to you and help you working in the right direction.

Learn and discuss
Obligatory reading:
 * Any potential contributor new to our community is encouraged to follow the Landing instructions.
 * How to become a MediaWiki hacker is a good place to start learning your skills and becoming a better candidate.
 * Lessons learned for mentorship programs.

To set up your MediaWiki developer environment, we recommend you start installing a local instance using mediawiki-vagrant. You can also have a fresh MediaWiki to test on a remote server. Just get developer access and request your own instance at Wikitech.

If you have general questions you can start asking at the |Discussion page. IRC channel is also a good place to find people and answers. We do our best connecting project proposals with Bugzilla reports and/or wiki pages. Other contributors may watch/subscribe to those pages and contribute ideas to them. If you can't find answers to your questions, ask first in those pages. If this doesn't work then go ahead and post your question to the wikitech-l mailing list.

Add your proposal

 * Use your user page to introduce yourself.
 * Draft your project in a separate page in main namespace, or as subpage of an existing project or extension your idea will integrate with. Try to pick a short, memorable and catchy title which communicates your core idea on how to tackle the issue/project you chose.
 * Use the template. For GSoC proposals, remember to add them to the proposals category and the table so that it's clear it's a proposal (not yet approved) and you're working on it.
 * The GSOC student guide is a good resource for anybody willing to write a good project proposal. And then there is a list of DOs and DON'Ts full of practical wisdom.

Featured project ideas
Below you can find a list of ideas that already have gone through a reality check and have mentors confirmed. You can find more suggestions in our list of Raw projects.

But before, let us talk about...

Your project
That's right! If you have a project in mind we want to hear about it. We can help you assessing its feasibility and we will do our best finding a mentor for it.

Here you have some guidelines for project ideas:


 * Opportunity: YES to projects responding to generic or specific needs. YES to provocative ideas. NO to trivial variations of existing features.
 * Community: YES to projects encouraging community involvement and maintenance. NO to projects done in a closet that won't survive without you.
 * Deployment: YES to projects that you can deploy. YES to projects where you are in sync with the maintainers. NO to projects depending on unconvinced maintainers.
 * MediaWiki != Wikipedia: YES to generic MediaWiki projects. YES to projects already backed by a Wikimedia community. NO to projects requiring Wikipedia to be convinced.
 * Free content: YES to use, remix and contribute Wikimedia content. YES to any content with free license. NO to proprietary content.
 * Free API: YES to the MediaWiki API. YES to any APIs powered with free software. NO to proprietary APIs.

Mentors: looking for mentors.

Internationalization and localization
Internationalization (i18n) and localization (L10n) are part of our DNA. The Language team develops features and tools for a huge and diverse community, including 287 Wikipedia projects and 349 MediaWiki localization teams. This is not only about translating texts. Volunteer translators require very specialized tools to support different scripts, input methods, right-to-left languages, grammar...

Below you can find some ideas to help multilingualism and sharing of all the knowledge literally for everybody in their own language.

Generic, efficient Localisation Update service
We do not know how much current Localisation Update extension (LU) is used outside the Wikimedia Foundation, but we believe that number to be quite low. Reasons for low adoption are, among others, the current requirement to set up cron jobs and do other manual configuration. We can eliminate such complexity in new version (LUv2) by relying on a new, separate service (server), which could be hosted by translatewiki.net for example.

The service would keep track of translation updates in way which allows clients to only request a delta of changes since the last update. Currently, the client downloads all latest translation for all extensions and languages to local cache, and then compares which translations can be updated. If we also take into account that not all wikis need all the 300 or so languages, the updates will become a lot faster.

The service would ideally not be MediaWiki-specific, so that other software projects can use it to implement low-delay localisation updates.


 * Skills: PHP for the extension (client), language of choice for the backend (server), capable of designing a protocol between the server and client.
 * Mentors: Niklas Laxström, Kartik Mistry

Extensive and robust localisation file format coverage
Translate extension supports multiple file formats. The formats have been developed "as needed" basis, and many formats are not yet supported or the support is incomplete. In this project the aim would be to make existing file formats (for example Android xml) more robust to meet the following properties: Example known bugs are 31331, 36584, 38479, 40712, 31300, 57964, 49412.
 * the code does not crash on unexpected input,
 * there is a validator for the file format,
 * the code can handle the full file format specification,
 * the code is secure (does not execute any code in the files nor have known exploits).

In addition new file formats can be implemented: in particular Apache Cocoon and AndroidXml string arrays have interest and patches to work on, but we'd also like TMX, for example. Adding new formats is a good chance to learn how to write parsers and generators with simple data but complicated file formats. For some formats, it might be possible to take advantage of existing PHP libraries for parsing and file generation. (More example formats other platforms support: OpenOffice.org SDF/GSI, Desktop, Joomla INI, Magento CSV, Maker Interchange Format (MIF), .plist, Qt Linguist (TS), Subtitle formats, Windows .rc, Windows resource (.resx), HTML/XHTML, Mac OS X strings, WordFast TXT, ical.)

This project paves the way for future improvements, like automatic file format detection, support for more software projects and extension of the ability to add files for translation by normal users via a web interface.


 * Skills: PHP, XML, aware how to write robust and secure PHP code
 * Mentors: Niklas Laxström, Siebrand Mazeland

Multilingual, usable and effective captchas
This project is very ambitious and challenging. Current CAPTCHAs are mostly broken, and still they are important to guard web sites like Wikipedia from a lot of spam. Over three millions captchas are filled every month on Wikimedia projects. Risk of failure is high, but when it succeeds, the rewards may be huge.

This project has a large research, design and user test component. The student will research and assess ways to use different CAPTCHA options, designed for multilingualism, to identify a more effective CAPTCHA than the current implementation used by Wikimedia. The student will create an implementation for use in MediaWiki of the identified CAPTCHA method. See related bug 32695 (mostly focused on the reCAPTCHA-like solution with Wikisource integration, see also Merge proofread text back into Djvu files). Some prototypes have been designed a while ago.

Preliminary discussion and general questions to mentors should happen on Talk:CAPTCHA; please create specific proposals/applications as subpages of the page CAPTCHA and discuss them on talk.


 * Skills: Design, JavaScript and PHP; preferably experience researching or developing CAPTCHA systems.
 * Mentors: Pau Giner; User:Emufarmers

One stop translation search


A Special:SearchTranslations page has been created for the Translate extension to allow searching for translations. However it has not been finished and it lacks important features: in particular, being able to search in source language, but show and edit messages in your translation language. The interface has some bugs with facet selection and direct editing of search results is not working properly. It is not possible to search by message key unless you know the special syntax, nor to reach a message in one click. Interface designs are available for this page.


 * Skills: Backend coding with PHP, frontend coding with jQuery, Solr/ElasticSearch/Lucene
 * Mentors: Niklas Laxström, Nik Everett (for the Elasticsearch part if needed)

Wiki page translation revisited
The wiki page translation feature of the Translate extension has become successful. As the usage has grown to several dozens wikis, new issues have come up which if fixed would ensure smooth user experience and further expansion. Each issue alone is not a major thing, but together they make page translation less nice than it could be.
 * (bug 35489) The user is unable to set the page source language: this prevents translation to the wiki content language from other languages. For instance, Wikimedia chapters would often like to translate their reports from their language to English on Meta-Wiki.
 * (bug 34098) Currently the page title is always up for translation. For some pages the title is not relevant and unused because the content is consumed in other ways. If the translation admin could choose not to translate the page title, translators time would be saved.
 * (bug 51533) The interface on the pages itself has been nominated for redesign. Main issues are the language selection and calls to action. The first one takes too much space and is hard to use if there are many languages, the latter is hard to notice but in a place where it can break the page flow.
 * (bug 37297, 39415) Updating issues when moving or deleting translation units (for example to remove spam).
 * (bug 36298) The page Special:AggregateGroups is clunky, lacks features and does not scale well to thousands of pages. It needs some re-architecturing to stay usable.


 * Skills: mostly PHP, some JavaScript
 * Mentors: Niklas Laxström, Robin Pepermans

Tools for mass migration of legacy translated wiki content
The MediaWiki Translate extension has a page translation feature to make the life of translators easier. It allows structured translation of wiki pages separating text strings from formatting or images, and also tracks changes in the source pages (usually in English). You can see it in action (click the Edit view). Often, wikis have a lot of legacy content that requires tedious manual conversion to make it translatable. It would be useful to have a tool to facilitate the conversion. You would show the proof of concept in Meta-Wiki, a Wikimedia community looking forward for a project like this.


 * Skills: PHP, interest in usability and conducting user research.
 * Mentors: Niklas Laxström, Federico Leva.

UniversalLanguageSelector fonts for Chinese (or CJK) wikis
Chinese uses too many characters, and many are rarely used so it's not often installed on readers' systems. However including all of them in the font file makes it huge, so we may want to tailor the font file for every page based on characters used on that page.

As of writing, there isn't any "good" enough free font which includes all Chinese characters in Unicode and the "wiki" concept itself encourages collaborative content creation, so it would be nice to invite user to create a glyph for it when the system sees a character without existing data (remember we need free contents).

en:WenQuanYi and glyphwiki.org already have some online glyph creators which can be useful for us; Hanazono (with Japanese glyph) is (almost?) complete, but the size is still excessive. A "reduced" font, like the Autonym font, should be developed on GitHub and may prove useful outside MediaWiki too, depending on quality and bandwidth contraints of reusers.


 * Skills: PHP, Web frontend, Font creation and management. Some knowledge of CJK characters can be a plus.
 * Mentors: User:Liangent, User:DChan (WMF)

Collaborative spelling dictionary building tool
There are extensive spelling dictionaries for the major languages of the world: English, Italian, French and some others. They help make Wikipedia articles in these languages more readable and professional and provide an opportunity for participation in improving spelling. Many other languages, however, don’t have spelling dictionaries. One possible way to build good spelling dictionaries would be to employ crowdsourcing, and Wikipedia editors can be a good source for this, but this approach will also require a robust system in which language experts will be able to manage the submissions: accept, reject, filter and build new versions of the spelling dictionary upon them. This can be done as a MediaWiki extension integrated with VisualEditor, and possibly use Wikidata as a backend.


 * Skills: PHP, Web frontend. Bonus: Familiarity with VisualEditor and Wikidata.
 * Mentors: Amir Aharoni, Kartik Mistry

A system for reviewing funding requests
The goal of this project is to either create or adapt a free and open source review system for funding requests, applicable to Individual Engagement Grants, conference scholarships, and similar programs. The system will allow an administrator to specify the criteria by which the grants will be judged, and the importance of those criteria relative to each other. A defined set of reviewers will then score and comment on each application. Once this scoring is complete, the system will average the scores of all of the reviewers and apply the relative importance values specified by the administrator to produce a report showing how each proposal has been assessed. The system will therefore greatly aid the grantmakers in the selection process for funding requests.

The project will commence with a research phase to find if there are any free and open source software systems already released that could either be used or adapted. Upon finishing that research, the student will either modify an existing system that was found or build one from scratch, with support from the project mentors. More background on the overall project and some initial details can be found in the IdeaLab on meta-wiki.


 * Skills: PHP and MySQL.
 * Mentors: Siko Bouterse (Grantmaking), Bryan Davis (Platform Engineering), Dan Garry (Product/Platform Engineering)

MassMessage page input list improvements
The MassMessage extension currently allows for users to create lists of pages to send messages to using a parserfunction:. This is not very user friendly and should be replaced with a structured ContentHandler, probably in JSON. This page has some more technical details.

This will involve implementing a ContentHandler-based backend and a frontend for adding/editing/removing entries in JavaScript (with a non-JS fallback).


 * Skills: PHP, JS, probably minor design/CSS
 * Mentors: Legoktm, Reedy

Allowing 3rd party wiki editors to run more CSS features
The 3rd party CSS extension allows editors to style wiki pages just by editing them with CSS properties. It could be more powerful if we find a good balance between features and security. Currently this extension relies on basic blacklisting functionality in MediaWiki core to prevent cross-site scripting. It would be great if a proper CSS parser was integrated and a set of whitelists implemented.

Additionally, the current implementation uses data URIs and falls back to JavaScript when the browser doesn't support them. It would be a great improvement if the MediaWikiPerformAction (or similar) hook was used to serve the CSS content instead. This would allow the CSS to be more cleanly cached and reduce or eliminate the need for JavaScript and special CSS escaping.


 * Skills: PHP, CSS, JavaScript, web application security.
 * Mentors: Rusty Burchfield, ?.

Adding proper email bounce handling to MediaWiki (with VERP)
It's likely that many Wikipedia accounts have a validated email address that once worked but is out of date. Mediawiki do not currently unsubscribe users who trigger multiple non-transient failures and some addresses might be 10+ years old. Mediawiki should not keep sending email that is just going to bounce. It's a waste of resources and might trigger spam heuristics.

Two API calls needs to be added : For the second call, authentication will be needed so fake bounces are not a DoS vector or a mechanism for hiding password reset requests. The reason for the threshold is that some failure scenarios will resolve themselves, eg mailbox over quota, so we don't want to react to one bounce. A history of consecutive mails bouncing needs to be maintained.
 * One to generate a VERP address to use when sending mail from Mediawiki.
 * One that records a non-transient failure. That API call would record the current incident and if there had been some threshold level met, eg at least 3 bounces with the oldest at least 7 days ago, then it would un-confirm the user's address so mail will stop going to it.

There would be Mediawiki development component to this task to build the API, to add VERP request calls wherever email is sent, and an Ops component to route VERP bounces to a script (taking the mail as stdin, and optionally e.g. the e-mail address as arguments), which can then call the (authenticated) MediaWiki API method to remove the mail address.


 * Skills: PHP for MediaWiki; puppet and whatever other language for the Wikimedia backend; being able to define the requirements
 * Mentors: Jeff Green, Faidon Liambotis for backend, Legoktm for MediaWiki etc.

Automatic cross-language screenshots for user documentation
MediaWiki is a large and complex piece of software, and the user guide for core and those for extensions (like VisualEditor or Translate) each have a large number of images illustrating functions and stages of operation. However, these often date quickly as the software changes, and are generally only available in English or at best a few languages, which means that non-English users are not as well served. It would be fantastic to give documentation maintainers a way to It would probably be most sensible to do this by extending the existing browser testing framework, which is written in Ruby-based selenium, with an eye on scalability. (Crossbrowsertesting.com is also used for producing and sharing screenshots, but is not free and can't be scripted as granularly.)
 * capture the current look of the software with screenshots – or even screencasts – of the entire browser window, or sections of it, doing some scripted actions,
 * across the hundreds of languages that MediaWiki supports.


 * Skills: Ruby; browser testing.
 * Mentors: James Forrester and the Quality Assurance team; User:Amire80

Catalogue for MediaWiki extensions
MediaWiki can be enhanced with additional functionality by adding extensions. There are currently about 2000 extensions available on MediaWiki.org. However, it is hard to identify and assess which extension fits a particular need. Moreover, it is not clear which version of the extension to take for a particular MediaWiki version. And if you want to find the most popular or most frequently downloaded extensions, you'd have to go to a third party site like WikiApiary.

This situation leaves a lot of room for improvement and creative ideas. The current plan is to implement a rating system on WikiApiary (which is tracking MediaWiki use "in the wild") and syndicate the data to MediaWiki.org.

Here are some features that will bring great benefit to all the 3rd party users of MediaWiki:
 * An set of structured information about extension (this might be download numbers, release state, ratings or version compatibility). Some of this information can already be found on the extension pages.
 * A catalogue function where you can search for extensions, find similar extensions, sort them by popularity, authors, rating, etc.
 * The possibility to add external data such as WikiApiary's usage statistics
 * A redesign of the presentation layer, so that it is actually good fun to browse the extension catalogue

Technically, it might be an option to integrate with WikiData and be on the bleeding edge of the wiki way to data representation.

There's already a more detailed proposal page for a Gallery of extensions.


 * Skills: PHP, JavaScript and MySQL

Wikimedia Identities Editor
Mediawiki Community Metrics is a Wikimedia project which goal is to describe how the MediaWiki / Wikimedia tech community is doing.

Once the website with the metrics is reaching a first complete version, a web application to manage community identities is needed. A community member will access the web application and authenticate using OAuth or creating a new account. All the information about the member in Mediawiki Community Metrics will be presented, so the user can update her information, add new identities, the localization and so on.


 * Skills: Django or similar web framework to develop the application. OAuth and other authentication techs.
 * Mentors: Alvaro del Castillo, Daniel Izquierdo.

Book management in Wikibooks/Wikisource


We need a stable interface for reading and editing books. At the moment we have made ​​great progress, but the extension needs some features (especially bug 53286 and bug 52435) to be ready for installation in our wikis.
 * Skills: PHP, JS (JSON/JQuery etc), HTML, CSS and caching. Experience in UX design and MySQL is a plus.
 * Mentor: Raylton

Google Books > Internet Archive > Commons upload cycle
Wikisources all around the world use heavily GB digitizations for transcription and proofreading. As GB provides just the PDF, the usual cycle is:
 * 1) go to Google Books and look for a book,
 * 2) check if the book is already in IA,
 * 3) if it's not, upload it there with appropriate metadata (library),
 * 4) get the djvu from IA,
 * 5) upload it on Commons,
 * 6) use it on Wikisource.

What we miss right now is a tool for points 2-3, that would serve many other users outside the Wikimedia movement too. It could be
 * a python script for mass uploads for experienced users (building with Alex.brollo's tests) and/or
 * some web tool for more limited uploads (preferably as a Wikisource gadget, but also bookmarklet, tool hosted on Tool Labs or elsewhere, or even browser extension).

Subsequently, more work is possible. For points 4-5, we have the awesome IA-Upload tool, that could be further improved. Eventually, the script/tool above would be further developed to combine and automate all the passages, asking user interveention only when needed (e.g. metadata polishing and Commons categories).

Relevant Wikisource help pages include s:Help:Internet Archive and s:Help:Internet Archive/Requested uploads.


 * Skills: python, screenscraping, some JavaScript for the frontend.
 * Mentors:
 * Aubrey is available for "design" mentorship, paired with a technical expert. We can maybe ask help from a IA expert;
 * Yann (talk) is available for help regarding uploads of Google Books and files from IA;
 * Tpt is available as technical mentor. He has no special knowledge of InternetArchive and Google Books. Is also the creator of IA-Upload.

New media types supported in Commons
Wikimedia Commons a database of millions of freely usable media files to which anyone can contribute. The pictures, audio and video files you find in Wikipedia articles are hosted in Commons. Several free media types are already supported but there are more requested by the community, like e.g. X3D for representing 3D computer graphics or KML/KMZ for geographic annotation and visualization. Considerations need to be taken for each format, like security risks or fallback procedures for browsers not supporting these file types.


 * Skills: PHP at least. Good knowledge of the file type chosen will be more than helpful.
 * Mentors: Bryan Davis, ?.

OpenHistoricalMap & Wikimaps
Wikimaps is an initiative to gather old maps in Wikimedia Commons and place them in world coordinates with the help of Wikimedia volunteers. Connecting with OpenHistoricalMap the historical maps can be used as reference for extracting historical geographic information. Additionally, the resulting historical geodata can be connected back to the data repository of Wikimedia through Wikidata, creating a community maintained spatiotemporal gazetteer.

We hope to foster better visualisation of the raw data held by the OpenHistoricalMap by allowing the rendering to work temporally as well as spatially. The tile rendering software will be modified to support a date range while the OSM rails port will be addled by a time / date sliders so that the current OSM tools stack can work within a specific time and place.


 * Enhance the iD and The_Rails_Port so that a javascript time/date slider can be added to control the time period that is of interest.
 * Enhance the ID and The_Rails_Port so that meta-data hooks are added to the code that allow for custom deployments of both software. The intent is to support their use as dedicated user interfaces to certain applications (such as medieval walking path editing) while still using a generic data source.
 * Modify the Mapnik tile renderer to handle Key:start_date and Key:end_date.


 * Skills: Rails, javascripts, scripting
 * Mentors: Rob Warren (Muninn project), Shekhar Krishnan (Topomancy LLC), Jeff Meyer (GWHAT)

Semantic MediaWiki
Semantic MediaWiki is a lot more than a MediaWiki extension: it is also a full-fledged framework, in conjunction with many spinoff extensions, and it has its own user and developer community. Semantic MediaWiki can turn a wiki into a powerful and flexible collaborative database. All data created within SMW can easily be published via the Semantic Web, allowing other systems to use this data seamlessly.

There are more than 500 SMW-based sites, including wiki.creativecommons.org, docs.webplatform.org, wiki.mozilla.org, wiki.laptop.org and wikitech.wikimedia.org.

Multilingual Semantic MediaWiki
Semantic MediaWiki would benefit from being multilingual-capable out of the box. We could integrate it with the Translate extension. This can be done in some isolated steps, but there is a need to list all the things in need of translation and define appproach and priority for each of them. Some of the steps could be:


 * Fix the issues that prevent full localisation of Semantic Forms.
 * Enhance Special:CreateForm and friends (all the Special:Create* special pages by Semantic Forms) to create forms that are already i18ned with placeholders and message group for Translate extension.
 * Make it possible to define translation for properties and create a message group for Translate extension, similar to what CentralNotice does (sending strings for translation to Translate message groups).
 * There are lot of places where properties are displayed: many special pages, queries, property pages. Some thinking is required to find out a sensible way to handle translations on all these places.
 * Currently In most wikis, properties names are supposed to be hidden to the user, e.g. queries results are usually shown in infobox-like templates (whose labels could in theory be localised as all templates).

Translate would be fed with the strings in need of translation. Localised strings/messages would be displayed based on the interface language, that in core every user can set on Special:Preferences and with ULS is made way easier to pick for everyone including unregistered users.

For real field testing, WikiApiary could be used, or at worst translatewiki.net (quick deployments, little SMW content).


 * Skills: PHP and web frontend, has used Semantic MediaWiki and Semantic Forms is a plus.
 * Mentors: Niklas Laxström, Yaron Koren.

Simultaneous Modification of Multiple Pages with Semantic Forms
Right now the editing of multiple pages with Semantic Forms is rather cumbersome with users having to edit every page separately, then sending it off and waiting for the server reply to then click their way to the edit form for the next page. The aim of this project is to facilitate the simultaneous editing of the data of multiple pages displayed in a table, ideally giving a spreadsheet-like experience.

As an additional goal there should be an autoedit-like functionality for multiple pages. Using the #autoedit parser function it is currently possible to create links that, when clicked on, create or edit one page automatically in the background, with a preloaded set of values. With the new function it would be possible to modify several pages at once.

Project goals:
 * display data of multiple pages in a tabular form with each line containing the data of one page and each cell containing an input for one data item
 * provide an optimized user interface for this form that allows for rapid navigation and editing with a special focus on keyboard navigation
 * optional: for the data items use the input widgets as specified in an applicable form definition
 * when submitted store the modified data using the job queue
 * provide a parser function that allows the automatic modification of multiple pages

This project involves challenges regarding working with the MediaWiki API and user rights management to protect the wiki from unauthorized mass-modification of pages.


 * Skills: PHP, JavaScript
 * Mentors: Stephan Gambke, Yaron Koren

Switching Semantic Forms autocompletion to Select2
The Semantic Forms extension makes use of the jQuery UI Autocomplete JavaScript library for autocompletion - including for multiple-value autocompletion and combo boxes. This solution has worked fine, but better tools now exist. This project would switch Semantic Forms to use the Select2 JS library for autocompletion, which will enable a number of important improvements:


 * "Tokenization" of values (putting squares around each term), which has become increasingly common in user interfaces
 * Flexible autocompletion for characters with accents
 * Display of an image associated with each term
 * Displaying values in a tree-type structure
 * Much better support for autocompletion on remote data sets

Some of these are possible to do just by taking advantage of more recent additions to jQuery UI Autocomplete, but overall Select2 is the much more complete system.

The last of these items, especially, could involve some interesting design work in enabling admins/users to define the layout of remote data sets.


 * Skills: JavaScript and CSS. Experience with PHP or MediaWiki is helpful, but not necessary.
 * Mentors: Yaron Koren, Stephan Gambke

Updating RDFIO to use templates
RDFIO extends the RDF import and export functionality in Semantic MediaWiki by providing import of arbitrary RDF triples, and a SPARQL endpoint that allows write operations. Since most SMW is stored via templates, RDFIO should be able to create and modify template calls based on the triples it is importing (1). At first, assumptions will need to be made about the schema of the imported data to make this work effectively (see, e.g., 2) Then, we can see which of these assumptions can be relaxed, thereby increasing interoperability between SMW and the rest of the semantic web.


 * Skills: PHP, understanding of semantic web technology, primarily RDF and SPARQL.
 * Mentors: Joel Sachs, Samuel Lampa

Visual translation: Integration of page translation with VisualEditor
The wiki page translation feature of the Translate extension does not currently work with VisualEditor due to the special tags it uses. More specifically, this is about editing the source pages that are used as the source for translations, not the translation process itself. The work can be divided into three steps:
 * 1) Migrate the special tag handling to a more standard way to handle tags in the parser. This need some changes to the PHP parser for it to be able to produce wanted output.
 * 2) Add support to Parsoid and VisualEditor so that editing page contents preserves the structures that page translation adds to keep track of the content.
 * 3) Add to VisualEditor some visual aid for marking the parts of the page that can be translated.

This is likely to be a difficult project due to complexities of wikitext parsing and intersecting multiple different products: Translate, MediaWiki core parser, Parsoid, VisualEditor.


 * Skills: PHP, JavaScript, wikitext parsing
 * Mentors: general mentors + Niklas Laxström

Annotation tool that extracts statements from books and feed them on Wikidata
Wikidata is a free knowledge base that can be read and edited by humans and machines alike. If you understand the difference between plain text and data you will understand that this project is Wikipedia's Game-changer. The conversion from text to Wikidata content fields has started in Wikipedia and sister projects and continues diving deeper, but there is still a lot to do!

Now think about this: you are at home, reading and studying for pleasure, or an assignment, or for your PhD thesis. When you study, you engage with the text, and you often annotate and take notes. What about a tool that would let you share important quotes and statements to Wikidata?

A statement in Wikidata is often a simple subject - predicate - object, plus a source. Many, many facts, in the books you read, can be represented in this structure. We an think of a way to share them.

A client-side browser plugin or script or app that would take some highlighted text, offering you a GUI to fix up the statement and source, and then feed it into Wikidata.

We could unveil a brand-new world of sharing and collaborating, directly from you reading.

Possible projects:  
 * Pundit http://www.thepund.it/ (the team is aware of Wikidata and willing to collaborate).
 * Annotator https://github.com/okfn/annotator for which Extension:Annotator exists (from Prototyping inline comments past project).
 * Mentors: Aubrey is available for mentorship, paired with a technical expert.

Welcoming new contributors to Wikimedia Labs and Wikimedia Tool Labs
Wikimedia Labs is the hosting platform for volunteer and experimental development. Currently we have difficulties matching new contributors with existing projects. Our documentation for newcomers needs improvements as well. To make it more complex, currently we're integrating the Tools Labs project, with people coming from an existing community with own documentation and processes. As a result, many potential Labs contributors are either lost or they end up creating new projects unaware of existing projects with very similar goals. We welcome project proposals to address this problem, improving our current documentation and finding a way to organize and promote the active initiatives among the more than 170 projects hosted in Labs. Proposals should also include ideas for ways to track and document short-lived projects and distinguish between those that are active and those that are abandoned.


 * Skills: technical writing, organization.

Wikidata is a free knowledge base that can be read and edited by humans and machines alike. If you understand the difference between plain text and data you will understand that this project is Wikipedia's Game-changer.

Wikidata is one of the newest Wikimedia projects. It is not known and understood enough yet. Your task is to help change this by helping with the outreach efforts around Wikidata. How we're going to do this? Let's figure it out. Let's plan a social media campaign? Let's make documentation easier to find and understand? Let's showcase amazing things around Wikidata? Let's do some storytelling? Or something completely different? Based on your skillset and interest we will figure out the right steps together.


 * Skills: at least a basic understanding of Wikidata, ideas and writing skills

Evaluate MediaWiki web API client libraries
API:Client code, our list of available web API client libraries, is currently a mishmash of libraries of varying quality, some completely unmaintained. At some point in the future, it would be ideal to have a list of officially approved libraries in several popular programming languages. This would help the developers of applications that consume our API ("third-party" developers) easily know

This intern would help prepare for that glorious future by:


 * Updating the API:Client code list to make sure it includes all the extant MediaWiki-specific client libraries.
 * Evaluating the existing MediaWiki API client libraries in several major languages (both on a technical basis and judging how responsive the developers are) to pick the best in each language. The number of languages is not quite fixed and depends on how many libraries exist in each language, how clear-cut the differences are, and so on, but probably we want to evaluate libraries in at least four languages during this internship.
 * Writing up some detailed specifications of what we ought to do next to raise each of them to Official "Use This" Library status.

Skills needed:
 * Some programming skill in at least one or two programming languages. (Languages we're interested in include Java, PHP, Python, Ruby, C#, JavaScript and Node.js, Go, .NET, Perl, Clojure, OCaml, and Scala, but other languages might also be welcome.)
 * Willingness and ability to learn the basics of several programming languages over the course of the one-month Community Bonding Period and the three-month internship.
 * Writing English prose.


 * We are considering modifying this project to reduce the time spent on evaluation and add time for the intern to actually contribute to one of the client libraries, through bug-filing, documentation, and code improvements.

Wikimedia Performance portal
MediaWiki and the ecosystem of services that support it in Wikimedia's production environment emit lots of performance timing data, such as the time it took to process some request or the speed of a network link. Much of this data is aggregated in two log aggregation systems with graphing capabilities. But the data is not well curated, mixing important metrics with unimportant ones. The data needs a curator! We have http://performance.wikimedia.org/ provisioned, and we'd like that space to feature some key performance metrics about the Wikimedia cluster, perhaps accompanied by some glosses that help readers interpret the data. (See gdash.wikimedia.org for an approximate system.) Ori Livneh, Senior Performance Engineer at the Wikimedia Foundation, will act as mentor. He will be happy to provide an overview of the data that is available, the means of accessing it, and the tooling available for plotting it. This task is suitable for anyone with interest in data analysis and performance analysis. Some facility with a language with good data analysis libraries like Python or R is desirable but not required.

Make Wiktionary definitions available via the dict protocol
The dict protocol (RFC 2229) is a widely used protocol for looking up definitions over the Internet. We'd like to make Wiktionary definitions available for users. Doing that using the dict protocol would help drive the use and usefulness of Wiktionary, as well.

Possible users:
 * Tablet readers often have dictionary lookup included.
 * Students writing papers would have access to a large corpus of words.
 * Mobile applications for Wiktionary would be less tied to MediaWiki itself.

MediaWiki development
If you're a programmer, we have lots of things for you to do. (To do: copy some relevant ideas from http://socialcoding4good.org/organizations/wikimedia )

Effective anti-spam measures
Use something like a minimal version of Extension:ConfirmAccount to require human approval of each account creation. That is the applicant fills in forms for user name, email and a brief note about who they are and why they want to edit the wiki. Also set the wiki so that the initial few edits also need approval. Then have it that any bureaucrat can approve the account creation, initial edits and remove the user id from moderation. Rob Kam (talk) 09:50, 1 December 2013 (UTC)


 * Requirements have to be clarified here: the proposed approach is much more complex than ConfirmAccount, not "minimal". Perhaps what you want is a sandbox feature? --Nemo 10:32, 1 December 2013 (UTC)


 * Sandbox feature looks good, but for all new accounts not just translators. Rob Kam (talk) 10:49, 1 December 2013 (UTC)

Parsoid
The Parsoid project is developing a wiki runtime which can translate back and forth between MediaWiki's wikitext syntax and an equivalent HTML / RDFa document model with better support for automated processing and visual editing. It powers the VisualEditor project, Flow and semantic HTML exports.

Parser migration tool
Periodically, we come across some bit of wikitext markup we'd like to deprecate. See Parsoid/limitations, Parsoid/Broken wikitext tar pit, and (historically) MNPP for examples. We'd like to have a real slick tool to enhance communication with WP editors about these issues:
 * It would display a list of wiki titles (filtered by wikipedia project) which contain deprecated wikitext. Each title would link to a page which would briefly describe the problem(s), general advice on how the wikitext should be rewritten, and (perhaps) some previously-corrected pages for editors to look at.
 * Ideally this would be integrated with a wiki workflow and/or contain "revision tested" information so that editors can 'claim' pages from the list to fix and don't step on each others work. Fixed/revised pages would be removed from the list until their new contents could be rechecked.
 * It should be as easy as possible for Parsoid developers to add new "bad" pattern tests to the tool. These would get added to the testing, with appropriate documentation of the problem, so that editors don't have to learn about a new tool/site for every broken pattern.
 * Some of these broken bits of wikitext might be able to be corrected by bot. The tool could still create a tasklist for the bot and collect and display the bots' fixes for editors to review.
 * The backend which looks for broken wikitext could be based on the existing round-trip test server. Instead of repeatedly collecting statistics on a subset of pages, however, it would work its way through the entire wikipedia project looking for broken wikitext (and preventing regressions).
 * Some cleverness might be helpful to properly attribute bad wikitext to a template rather than the page containing the template. This is probably optional; editors can figure out what's going on if they need to.


 * Skills: node.js, and probably MediaWiki bots and/or extensions as well. A candidate will ideally have some node.js experiences and some notions of web and UX design.  This task could be broken into parts, if a candidate wants to work only on the front-end or back-end portions of the tool.
 * Mentors: C. Scott Ananian, Subramanya Sastry

VisualEditor plugins
VisualEditor is a rich visual editor for all users of MediaWiki so they don't have to know wikitext or HTML to contribute well formatted content. It is our top priority and you can already test it on the English Wikipedia. While we focus on the core functionality, you could write a plugin to extend it, such as to insert or modify Wikidata content. There are also many possibilities to increase the types of content supported, including sheet music, poems, timelines…


 * Skills: HTML / JavaScript / jQuery development is required. A good grasp of UX / Web design will make a difference.
 * Mentors: James Forrester, Roan Kattouw, Trevor Parscal.

VisualEditor support for EasyTimeline
Also mentioned at.

Flow
Flow brings a modern discussion and collaboration system to MediaWiki. Flow will eventually replace the current Wikipedia talk page system and will provide features that are present on most modern websites, but which are not possible to implement in a page of wikitext. For example, Flow will enable automatic signing of posts, automatic threading, and per-thread notifications.

Templates and bits and pieces for non-WMF MediaWiki installs
For a less than guru level non-WMF Mediawiki wiki admin: After the initial install of a MediaWiki wiki then finding out that templates are also an essential part of setting up a wiki. They have to figure out which wiki to use as a source and then which templates. When the XML gets imported into the destination wiki, they've also got red links to missing sub-templates, details that apply specifically to the source wiki, (e.g. the name and logo of that source wiki) and maybe other features like common.css and common.js need tweaking. Afterwards how do they keep theses features up to date with bug fixes and other changes.

Some of the problems encountered with setting up templates are discussed at Help talk:Templates

There ought to be a simpler and efficient way to do this. Installing and maintaining extensions is mostly a neat and simple process. A central repository for templates and other bits and pieces would be much neater and more manageable way for implementing the rest of the essential features used on MediaWiki wikis, than everyone figure it out for themselves each time anew.

Improving the skinning experience
Research how to make the development of skins for MediaWiki easier. Many users complain about the lack of modern skins for MediaWiki and about having a hard time with skin development and maintenance. Often sys admins keep old versions of MediaWiki due to incompatibility of their skins, which introduces security issues and prevents them from using new features. However, little effort was done to research the exact problem points. The project could include improving skinning documentation,organizing training sprints/sessions, talking to users to identify problems, researching skinning practices in other open source platforms and suggesting an action plan to improve the skinning experience.

Maria Miteva proposed this project.

Extensions
Check Manual:Extensions and extension requests in Bugzilla.

An easy way to share wiki content on social media services
Wikipedia, as well as other wikis based on MediaWiki, provide an easy way to accumulate and document knowledge, but it is difficult to share it on social media. According to https://strategy.wikimedia.org/wiki/Product_Whitepaper 84% of Wikimedia users were Facebook users as well in 2010, with the portion incresing from previous years. The situation is probably similar with other social media sites. It only makes sense to have an effective "bridge" between MediaWiki and popular social media site. More details here: Product Whitepaper.

Some previous work you can use as a base, improve, or learn from:


 * Extension:Widgets
 * Extension:WidgetsFramework - experimental extension
 * Extension:AddThis
 * Extension:Facebook - just Facebook
 * Extension:WikiShare - unstable version, seems like it's not worked on any more

Extension:OEmbedProvider
Finish Extension:OEmbedProvider, as proposed here. See also Bug 43436 - Implement Twitter Cards

Leap Motion integration with MediaWiki
MediaWiki has a wide user base and a lot of users today prefer touch based interfaces. Gesture based interface are friendly and the latest trend. Leap Motion provides controllers that can recognize gestures. It can be integrated with MediaWiki products like Wikisource. As an example, this would make it more friendly for users to flip through pages in a book. Another advantage of using gesture recognition would be to include turning through multiple chapters or pages at a time by identifying the depth of user's finger's motion.

It would also be helpful for flipping through images in Wikimedia Commons.

(Project idea suggested by Aarti Dwivedi).

Work on RefToolbar
The en:Wikipedia:RefToolbar/2.0 extension is incredibly useful, especially for new editors but also for experienced editors (I use it every day, and I've got a few miles under my belt!). But it suffers from bugs and problems, and there are a lot of improvements that could be made. For instance: adding additional reference types, adding fields for multiple authors, tool-tip help guidance, etc. I also suspect it will need an upgrade to match Lua conversions of common cite templates. Also, I don't think this is in wide deployment on other wikis, so translation/deployment could be a project. Looking at the talk page, there are a couple people starting to work on this but serious development isn't happening (so I'm not sure who would mentor this) but the code was recently made accessible. At any rate, it is an extension that really needs some work and where improvements would have immediate benefit for many editors.

Project idea contributed by Phoebe (talk) 23:23, 22 March 2013 (UTC) [n.b.: I can't mentor on the tech side, but can give guidance on the ins and outs of various citation formats in the real world & how cite templates are used on WP].

Global, better URL to citation conversion functionality
Suppose, in Wikipedia, all that needed to be done to generate a perfect citation was to provide a URL? That would be a tremendous step toward getting a much higher percentage of text in Wikipedia articles to be supported by inline citations.

There are already expanders (for the English Wikipedia, at least) that will convert an ISBN, DOI, or PMID, supplied by an editor, into a full, correct citation (footnote). These are in the process of being incorporated into the reference dialog of the VisualEditor extension, making it almost trivial (two clicks, paste, two clicks) to insert a reference.

For web pages, however, the existing functionality seems to be limited to a Firefox add-on. Its limits, besides the obvious requirement to use that browser (and to install the add-on), include an inability to extract the author and date from even the most standard pages (e.g., New York Times), and the lack of integration with MediaWiki.

For a similar approach, using a different plug-in/program, see this Wikipedia page about Zotero.

A full URL-to-citation engine would use the existing Cite4Wiki (Firefox add-on) code, perhaps, plus (unless these exist elsewhere) source-specific parameter specifications. For example, the NYT uses "" for its author information; that format would be known by the engine (via a specifications database). Each Wikipedia community would be responsible for coding these (except for a small starter set, as examples), in the way that communities are responsible for TemplateData for the new VisualEditor extension.

(Project idea suggested by John Broughton.)

Education Program, outreach and projects
The Wikipedia Education Program helps professors and students contribute to Wikipedia as part of coursework. The current Education Program extension provides features for keeping track of the institutions, courses, professors, students and volunteers involved in this. However, the extension has several limitations and will be largely rewritten. Help is needed to design and build new software to support both the Education Program and other related activities, including topic-centric projects and edit-a-thons.

This project offers tons of opportunities to learn about different facets of software development. There's work to be done right away on UX, flushing out details of requirements, and architecture design. On this last point, a fun challenge we'll face is creating elegant code that interfaces with a not-so-elegant legacy system. Another challenge will be to create small deliverables that are immediately useful, that can replace parts of the current software incrementally, and that can become components of the larger system we're planning.

Student developers eager to dive into coding tasks can also take bugs on the current version of the software&mdash;much of which will remain in production for a while yet. In doing so, they'll practice their code-reading skills, and will get to deploy code to production quickly. :)

Support for vizGrimoireJS-lib widgets
vizGrimoireJS-lib is a JavaScript visualization library for data about software development, collected by MetricsGrimoire tools. It is used, for example, for the MediaWiki development dashboard.

The idea of this project is to build a module for MediaWiki so that vizGrimoireJS-lib widgets can be included in MediaWiki pages, with a special markup. All widgets get their information from JSON files, and accept several parameters to control visualizacion. Currently, vizGrimoireJS-lib widgets can be included in HTML pages with a simple HTML markup (sing HTML attributes to specify the parameters of the widget. This behavior will be translated into MediaWiki markup, so that the whole MediaWiki development dashboard could be inserted in MediaWiki pages.

Wikimedia Commons / multimedia

Support for text/syntax/markup driven or WYSIWYG editable charts, diagrams, graphs, flowcharts etc.
Resuscitate Extension:WikiTeX and fold Extension:WikiTex into it.

Provide a way to create interactive 2D/3D timelines and infographics à la Java applets, AJAX, Flash
We almost surely don't want to invent our own markup, but SVG probably doesn't suffice and we surely won't use any proprietary format. Ideally we would adopt some syntax/format/technology already adopted and supported by a lively community, preferably offering a certain amount of existing timelines/infographics and other resources which we would then be able to directly use on Wikimedia projects, save copyright incompatibilities. Perhaps http://timeline.knightlab.com/, used by Reasonator?

Accessibility for the colour-blind
Commons has a lot of graphs and charts used on Wikipedia and elsewhere, but few consider how they look with colour blindness, mostly because the creator/uploader has no idea. Accessibility lists some tools that can be used to automatically transform images into how they are seen by colour blind people. We could run such automated tools on all Commons graphs and charts and reporting the results, ideally after assessing automatically in some way that the resulting images are not discernible enough, lower than some score. The warnings can be relayed with some template on the file description or directly to the authors and can havhe a huge impact on the usefulness of Commons media.

Depending on skills and time constraint, the project taker would do 1, 1-2 or 1-3 of these three steps: 1) develop the code for such an automatic analysis based on free software, 2) identify what are the images to check on the whole Commons dataset and run the analysis on it producing raw results, 3) publish such results on Commons via bot in a way that authors/users can notice and act upon.

Removing inline CSS/JS from MediaWiki
One of the future security goals of MediaWiki is to implement Content Security Policy. This is an HTTP header that disallows inline JavaScript and CSS as well as scripts and styles from disallowed domains. One of the big steps to achieving this is to remove all inline CSS and JavaScript from MediaWiki HTML. Some of the places inline scripting/styling is used: Fixing all of these inline scripts and styles is too big a task for a single mentor program. However, working on one or two, and slowly chipping down on the inline JS and CSS can help to move closer toward the final goal. This project obviously requires, at the very least, basic HTML and JavaScript knowledge, but some parts are more difficult than others. For example, bullet points 2 and 3 require only basic MediaWiki knowledge, but bullet point 1 requires altering the Parser class, and thus mandates a deeper understanding of MediaWiki and how it parses wikitext.
 * Inline styling in wikitext is translated to inline styling in HTML
 * ResourceLoader is mostly good, but the loader script (at the top and bottom of page) is inline JavaScript
 * Data such as user preferences and ResourceLoader config variables is embedded into the HTML as inline JSON, when it should be in HTML attributes
 * Many extensions use inline styling rather than ResourceLoader modules

Merge proofread text back into Djvu files
Wikisource, the free library, has an enormous collection of Djvu files and proofread texts based on those scans. However, while the DjVu files contain a text layer, this text is the original computer generated (OCR) text and not the volunteer-proofread text. There is some previous work about merging the proofread text as a blob into pages, and also about finding similar words to be used as anchors for text re-mapping. The idea is to create an export tool that will get word positions and confidence levels using Tesseract and then re-map the text layer back into the DjVu file. If possible, word coordinates should be kept.

Hopefully, it will be possible to reuse part of existing proofreading/OCR correction/OCR training software such as the OCR editor by the National Library of Finland.

See also m:Grants:IdeaLab/Djvu text layer editor.

Mentors and skills:
 * Project proposed by Micru. I have found an external mentor that could give a hand on Tesseract, now I'm looking for a mentor that would provide assistance on Mediawiki.
 * Aubrey can be a mentor providing assistance regarding Wikisource, and some past history of this issue. Not much, but glad to help if needed.
 * Rtdwivedi is willing to be a mentor.

Distributed cron replacement
A common requirement in infrastructure maintenance is the ability to execute tasks at scheduled times and intervals. On Unix systems (and, by extension, Linux) this is traditionally handled by a cron daemon. Traditional crons, however, run on a single server and are therefore unscalable and create single points of failure. While there are a few open source alternatives to cron that provide for distributed scheduling, they either depend on a specific "cloud" management system or on other complex external dependencies; or are not generally compatible with cron.

The Wikimedia Labs has a need for a scheduler that:
 * Is configurable by traditional crontabs;
 * Can run on more than one server, distributing execution between them; and
 * Guarantees that scheduled events execute as long as at least one server is operational.

The ideal distributed cron replacement would have as few external dependencies as possible.

System documentation integrated in source code
It would be really nice if inline comments, README files, and special documentation files could exist in the source code but be exported into a formatted, navigable system (maybe wiki pages or maybe something else). It could be something like doxygen, except better and orientated to admins and not developers. Of course it should integrate with mediawiki.org and https://doc.wikimedia.org.

The idea would be that one could:
 * Keep documentation close to the code and thus far more up to date
 * Even enforce documentation updates to it with new commits sometimes
 * Reduce the tedium of making documentation by using minimal markup to specify tables, lists, hierarchy, and so on, and let a tool deal with generating the html (or wikitext). This could allow for a more consistent appearance to documentation.
 * When things are removed from the code (along with the docs in the repo), if mw.org pages are used, they can be tagged with warning box and be placed in maintenance category.

Proposed by Aaron Schulz.

Ranking articles by pageviews for wikiprojects and task forces in languages other than English
Currently we have an amazing tool which every month determine what pages are most viewed for a Wikiproject and then provides a sum of the pageviews for all articles within that project. An example of the output for WikiProject Medicine in English.

The problems is that this tool only exists in English and is running on toolserver rather than Wikimedia Labs. So while we know what people are looking at in English, and this helps editors determine what articles to work on, other languages do not have this ability.

Additionally we are do not know if the topics people look up in English are the same as those they look up in other languages. In the subject area of medicine this could be the basis of a great academic paper and I would be happy to share authorship with those who help to build these tools.

A couple of steps are needed to solve this problem:
 * 1) For each article within a Wikiproject in English, take the interlanguage links stored at wikidata, and tag the corresponding article in the target language
 * 2) Figure out how to get Mr. Z's tool to work in other languages . He supposedly is working on it and I am not entire clear if he is willing to have help. Another tool that could potentially be adapted to generate the data is already on Labs

Improving MediaWikiAnalysis
MediaWikiAnalysis is a tool to collect statistics from MediaWiki sites, via the MediaWiki API. It is a part of the MetricsGrimoire toolset, and it is currently used for getting information from the MediaWiki.org site, among others.

The stats currently collected by MediaWiki are only a part of what is feasible to collect, and the tool itself could be improved. Some possible directions:


 * 1) Explore in detail the MediaWiki API and extract as much information from it as possible.
 * 2) Improve efficiency and incremental retrieval of data
 * 3) Propose (and if possible, implement) changes to the MediaWiki API if needed, to support advanced collection of data.
 * 4) Use SQLAlchemy instead of MySQLdb for managing the MediaWikiAnalysis database.


 * Skills: Python, SQL, PHP (only in case of proposing changes to MediaWiki API)
 * Mentors: Alvaro del Castillo, Daniel Izquierdo, Jesus M. Gonzalez-Barahona

Beyond development
Featured projects that focus on technical activities other than software development.

Research & propose a catalog of extensions
Extensions on mediawiki.org are not very well organized and finding the right extension is often difficult. Listening community members you will hear about better management of extension pages with categorization, ratings on code quality, security, usefulness, ease of use, good visibility for good extensions, “Featured extensions”, better exposure and testing of version compatibility... This project is about doing actual research within our community and out there to come up with a proposal both agreed and feasible. A plan that a development team can just take to start the implementation.


 * Skills: research, negotiation, fluent English writing. Technical background and knowledge of MediaWiki features and web development features will get you sooner to the actual work.
 * Mentors: Yury Katkov + ?

 * Global user preferences
 * architecturally very important (if not critical) to a number of projects
 * As far as I remember, the backend for this is largely completed, it just needs a sensible UI
 * Andrew Garrett writes:
 * I tried to implement this when I completely refactored the preferences system in 2009. It was eventually reverted in r49932. The main blocker was basically considering a way to decide which preferences would have their values synchronised. A UI would need to be developed for that and you'd need some extensive consultation on that fact.
 * If you were to implement this, you could potentially use my original implementation as a guide, though it is reasonably "in the guts" of MediaWiki so you'd have to be reasonably confident "code diving" into unfamiliar software packages.


 * using onscreen keymaps from Narayam's code base to build a mobile-focused app where one could choose and load a keymap from. This would be a great app to have on the mobile app stores for Boot2Gecko and Android.


 * Moving categories (and updating members of it) members
 * Discussed endlessly; needs to be properly implemented; move support, etc. should already be there; just needs schema support and some software tweaks?


 * HTML e-mail support
 * Requires some design expertise, but it'd be nice to have MediaWiki e-mails stop looking as though they're from 1995, especially as they're much more visible nowadays with ENotif (email notifications) enabled on Wikimedia wikis
 * Some of this was done as part of Notifications.


 * Fix user renames to be less fragile and horrible
 * Lots of breakages from renames of users with a lot of edits; old accounts need to be fixed in a sensible way and new borkages need to be properly prevented


 * Let users rename themselves
 * Restrict to those with zero edits?
 * Or not?
 * Major community policy issues.


 * Group similar pages in watchlist
 * Possibly a gadget? Make it easier for editors to sort through their watchlists.
 * See en:User:Js/watchlist.js


 * Database layer should automagically add GROUP BY columns on backends that need them (PostgreSQL)
 * Will improve the MediaWiki installation and maintenance experience for all MediaWiki installations on PostgreSQL, SQL Server, Oracle, SQLite, or any other non-MySQL database.
 * Needs some database experience


 * Add user preference to deactivate/delete user account
 * might be possible to piggyback on the HideUser functionality that already exists in MediaWiki core


 * Add a read-only API for CentralNotice
