Google Summer of Code/2013

Join our meetup: GSoC and other open source internship programs 2013-04-12 00:00 UTC / 2013-04-11 17:00 PDT - San Francisco, CA, USA + video stream + IRC We are working in a proposal to participate again at Google Summer of Code. GSOC is the most popular among the open source mentorship programs where we get involved. You can find more information, FAQs and tutorials for students, mentors and org admins in the official website.

Now we are working on the project ideas in order to submit the application as Wikimedia Foundation. The deadline is March 29, but we want to submit it before. Help is welcome, especially from potential mentors!

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 ideas with a good fit for GSOC.

Project ideas

 * We are working on them. Your feedback is welcome.

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 raw list of possible projects.

Guidelines for project ideas:


 * Opportunity: YES to projects responding to generic or specific needs. YES to provocative ideas. NO to 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 relying on the maintainers' acceptance.
 * MediaWiki != Wikipedia: YES to generic MediaWiki projects. YES to projects already backed by a Wikimedia community. NO to projects relying on Wikipedia's acceptance.
 * 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.

Reuse / Remix / Contribute to Wikimedia content
The Wikimedia community maintains millions of articles, media files and data that anybody (including your software) can download, share, modify, remix. We offer a MediaWiki API to interact with this content in the Wikimedia servers. An API that is also available in most MediaWiki based sites.

We welcome projects aiming to get this content to the people that need it most. Projects converting regular users in contributors to the Wikimedia pool of free knowlege. Projects categorizing, connecting or remixing this content and obtaining better or simply unexpected results. Surprise us!

We also welcome improvements to the API, enabling the enablers. Localized errors and warnings, RESTful style Content API and API versioning are some of the features waiting for a developer in our API roadmap.

Skills: depends on your project, but understanding PHP will be good in any case.

Mentors: Yurik Astrakhan as default. Others might be available depending on your project.

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 at the English Wikipedia. While we focus on the core functionality, you could write a plugin to extend it, for instance with syntax higlighting, or insertion of video or Wikidata content. There are also many possibilities to increase the types of content supported, including sheet music, source code, poems, timelines…

Skills: HTML / JavaScript / jQuery development is required. A good grasp of UX / Web design will make a difference.

Mentors: James Forrester.

Wikidata features
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!

The Wikidata team welcomes your suggestions and provides you with some ideas.

Entity Suggester
Wikidata, and specifically the Wikibase extension, could be a lot smarter than it is right now e.g. by suggesting fields to fill and probable values. For example: when an editor edits an item about a person that is still missing the date of birth, this should be suggested as a possible property. Or when the editor is entering the sex of the person, Wikidata should be smart and suggest the ones that are used most for these properties first. Think of it as something very similar to the famous "people who bought x also bought y" systems.

3rd party client
Currently the Wikidata client is only set up to directly serve data to the Wikimedia projects. The goal of this project is to also allow 3rd party clients to consume Wikidata data in the same way. For example, it is missing propagation of changes to clients out of the Wikimedia cluster, so they would show up in the watchlist and recent changes of the 3rd party MediaWiki sites.

Mentors: Wikidata team available. Lydia Pintscher is provisionally acting as proxy.

Automatic category redirects
This is one of the oldest and most voted MediaWiki feature requests. MediaWiki has a feature called redirects where one page can redirect to another. However they do not work for categories. In the ideal system, if Category A redirects to B, and someone puts page foo in category A, then the page should show up in category B. If Someone changes Category A to redirect to Category C, all the pages put in category C have to have their links moved from Category A to Category B.

This project would involve several of the "core" components of core MediaWiki including the, the database schema, and class. However it is quite self contained. This project would also be quite beneficial to several wiki projects, especially multilingual projects like Wikimedia Commons.

Skills: PHP. SQL would be helpful.

Mentors: Brian Wolff.

Incremental data dumps
We offer data dumps of Wikipedia and other Wikimedia projects, allowing people to access to this knowledge where Internet connection is impractical, very costly or non-existent. The dumps for the larger projects are only getting larger i.e. 40GB for English Wikipedia. What is more, the update a month later will be another 40GB or more. In fact, only a small subset of that information is actually changed in the form of new pages, new revisions, or deleted revisions. Imagine if users of these files could download just the changes, plus a script that applied the changes. Imagine if the dumps could be written out using the previous month's dumps with such a scheme. Imagine running the German language Wikipedia dumps in 3 days instead of the current 16. This could be achieved by designing the right output format for the XML files containing text for all revisions.

Skills: XML, a scripting language such as Python or Perl

Mentors: ArielGlenn.

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.
