Template talk:Extension/LQT Archive 1

Hello, Is there any complaints if we add to this a link to where the extension can be seen in action? --Rick 03:28, 25 September 2006 (UTC)


 * No - that sounds sensible. --HappyDog 11:59, 25 September 2006 (UTC)
 * ditto -- :Bdk: 16:01, 25 September 2006 (UTC)

Formatting is weird
Take a look at Extension:OpenID. What's going on? --wikitravel:User:Evan


 * I'm not sure what you mean - please elaborate. --HappyDog 19:16, 21 October 2006 (UTC)

Here is?
Why the change from "This is a MediaWiki Extension" to "Here is a MediaWiki Extension"? I think it sounds frivolous. I propose it is reverted. If anyone is against reverting it, please speak up... --Fernando Correia 10:24, 1 February 2007 (UTC)


 * I agree, I reverted it.--Patrick 10:29, 1 February 2007 (UTC)

Tools
I propose that a new type is added to the list: "tool". This could be used to indicate modules that provide additional functionality to a MediaWiki installation. Examples would be Extension:AddPageService and Extension:Word2MediaWikiPlus. --Fernando Correia 13:52, 20 February 2007 (UTC)


 * Perhaps it would be even better to have a separate namespace for them. After all, they are not really extensions. -- Duesentrieb ⇌ 23:46, 22 February 2007 (UTC)

That may be a good way. Although they "extend" MediaWiki core functionality, they are really not extensions in the sense that they are called by MediaWiki code. Actually the call MediaWiki. They are similar to pywikipediabot and to the "maintenance" directory scripts. Anyway, I think a clarification on this would be helpful, because some tools used to be classified as extensions on Meta, and at the same time classified as Category:MediaWiki tools. --Fernando Correia 11:11, 23 February 2007 (UTC)


 * The namespace was originally designed to hold all 3rd party extensions relating to MediaWiki (including tools that are worked on in the MediaWiki SVN tree, but which are not distributed as part of a standard MW install). Therefore tools should be included in the extensions namespace.  Only include tools that are specifically MediaWiki related, e.g. a Notepad style text editor that happens to be usable as an external MW editor (via user preferences) should perhaps be listed on a page of compatible editors, but it doesn't deserve its own page as a 'MediaWiki tool'.  Ditto stuff like apache or MySQL.


 * If we find that there are a sufficiently large number of MW-related tools that they warrant their own namespace then it might be worth creating one, but I suspect not. A better solution might be to use a different infobox for tools.  Or at the very least, it should be expressed in this box very clearly... --HappyDog 01:43, 22 March 2007 (UTC)

I'm glad you think they belong in the Extensions namespace. So, I propose that a new type is added to the list of extension types: "tool". --Fernando Correia 20:36, 22 March 2007 (UTC)

Categorise by author
I tried to get the template to categorise into Category:Extensions by "author" but couldn't get it to work. --Nad 21:38, 22 February 2007 (UTC)


 * Personally, I don't think this is very useful. I would suggest a better approach would be to create a new category called something like Extension authors, which authors can add to their user page, which should list all extensions they have authored.  Aside from satisfying the OCDers desire to categorise, I have yet to see a useful application of listing extensions by author... --HappyDog 01:43, 22 March 2007 (UTC)

Extension of multiple types
type = parser, hook, special puts it in "Category to catch extensions with an unrecognised type". It should be in all three extension categories. -- [[User:Skierpage|Skierpage 05:22, 17 March 2007 (UTC)


 * I added that combination. More combinations may have to be added. An alternative would have been to have a boolean parameter for each type.--Patrick 07:18, 17 March 2007 (UTC)


 * I guess the question is, why are we categorising and displaying this information? I would suggest it is so that people can find extensions, therefore 'special' is for extensions that are special pages (e.g. providing meta information), 'parser' is for extensions that add an extra piece of syntax.  If an extension is both, then it should be listed under it's main purpose.  E.g. a special page that uses a tag to gather its data (e.g. a special 'dump' page that provides a tarball of all pages that have the requested attribute in a &lt;dump&gt; tag) should be 'special'.  A tag that is supported by a special page (in the same way that the ISBN magic word works) should be 'parser'.  In cases where an extension is made up of all these different components, I feel that it should really be in a separate category, e.g. 'mixed'. --HappyDog 01:43, 22 March 2007 (UTC)


 * I'd rather have specific categories for each various extension type because it makes sorting/finding extensions easier and more intuitive. Special page extensions are not just extensions that are special pages but ones that manipulate/alter/edit/redisplay special pages, too. Multiple extension type support is badly needed in this template. It's too confusing to try and figure out which "mother" type extensions belong to, which is why I've been adding various categories for form, table, list, etc under category:extensions by category (nice redundant name, eh?). -Eep² 05:35, 29 July 2007 (UTC)
 * Support for up to 6 types in any order, added as of 2007-09-08, Egfrank 19:45, 8 September 2007 (UTC)

Extra info for template users
The template page could use some additional "noinclude" comments for extension users. In particular I am confused by some of the terms like hooks. Does this mean that the extension uses a hook or creates a hook? I assumed the former, but this and other items could use additional comments/instructions for newbies. --Sunergos 19:18, 22 April 2007 (UTC)


 * There is no 'hooks' parameter. 'hook' is one of the potential extension types, so if your extension creates a new parser tag then you should use this type. --HappyDog 22:59, 20 May 2007 (UTC)

Question about style object - css
Hi,

I'm interresting to use a similar extension into my wiki. I try to understand how it works but i don't understand where the class object are located (first line of your template: . I seen MediaWiki:Monobook.css but not found information about ext-infobox.

Thx, --Ouaibsky 13:48, 21 May 2007 (UTC)

extension by subcategory
I have created a duplicate template so that subcategorized extensions can reside within either category:extension or in their own category:subcategory, but not both. Bouncingmolar 01:07, 25 June 2007 (UTC)

Additional fields depends/suggests
Two additional fields could be added, one for extension dependancies (depends) and one for suggests which could be other extensions or third party code such as http://mootools.net or whatever --Zven 23:43, 25 June 2007 (UTC)

Extension Lang
I want to make Template:Extension/es in spanish

who agree?

--Hsilamot 00:27, 9 July 2007 (UTC)


 * I'm not sure how useful this would be. A Spanish version of the template would only be placed on Spanish versions of the extension page (e.g. Extension:MyExtension/es), and these pages will need to be translations of the English version to which they are connected.    Personally, I think attempting to translate the extension namespace is a bit of a lost cause, as it is written by the extension authors and changes so much that any translations will become out of date very quickly.  My recommendation would be that it is not worth creating this template unless there are a sufficient number of Spanish extension translations to make it worthwhile. --HappyDog 21:37, 11 July 2007 (UTC)

obsolete status
there are some extensions which may have become obsolete because of changes to mediawiki. should there be a special status for them? Extension:Email_notification - Bouncingmolar 02:29, 15 July 2007 (UTC)


 * Probably. I suggest 'obsolete' :-)  I will add that sometime soon and post here when it's done. --HappyDog 16:40, 24 July 2007 (UTC)


 * I have added it as historical, because retaining the pages is only for historical interest. I stole this idea from the enotif extension which the author used the template I have also added this template to the extension template conditionally for when the status is set to  historical. Bouncingmolar 23:26, 24 July 2007 (UTC)


 * 'obsolete' would probably be better, as that is what is used elsewhere on the site. The historical template was copied from meta in March because Extensions that had been copied here used it, but we should be working towards some kind of consistency here, I think.  That said, there may be a case for having both that I have not thought of... --HappyDog 23:48, 24 July 2007 (UTC)
 * ok i have changed historical to obsolete. I will just start tidying up a few loose ends Bouncingmolar 00:11, 25 July 2007 (UTC)


 * the template:obsolete doesn't seem to apply to extensions that have been replaced by better extension versions (see Extension:Open Office Export). I have left the template:historical for the moment Bouncingmolar 00:14, 25 July 2007 (UTC)


 * Hmmm... You're right. I guess we need to think about that.  Why extensions 'no good'?
 * Broken - don't work. These should have status 'experimental', I think.
 * Replaced by built-in functionality - obsolete from version X (but still useful for people using older versions)
 * Replaced by a different extension that offers the same (or more) functionality. Note that 'similar' is not a good enough reason, as some people may prefer extension 1, while others prefer extension 2.
 * I don't know if you can think of any more scenarios...
 * For that last one, I would suggest that instead of a new status, we should have a field 'replacedby' that allows you to specify an alternative extension as a replacement. The status may be 'beta status' but never finished because someone got there first.  We lose this info if we replace 'beta' with 'historical'.
 * --HappyDog 00:23, 25 July 2007 (UTC)
 * True re: historical/beta. hmmm  if only we could have more than one status. Bouncingmolar 00:40, 25 July 2007 (UTC)
 * This has since been reverted without any discussion by user:Voice of All Can someone please explain this? Bouncingmolar 05:42, 30 July 2007 (UTC)

field for extension stored externally
There are many extensions I have noticed that have their main content located on another site (eg bluecortex). Perhaps there should be a field such as "main site" which allows authors to put their content there, that way we can include in the template a warning message saying that more up to date info can be found on eg:bluecortex Bouncingmolar 00:48, 25 July 2007 (UTC) I would prefer if all the content was on mediawiki.org, but many authors are already avoiding that.. Bouncingmolar 00:49, 25 July 2007 (UTC)


 * Well, take a look at my WikiDB extension. That has most content held off-site, but still has a page here with the basic information and links to the detail.  I don't think there is any need to flag up 'off-site' extensions, except to note it on the extension page itself. --HappyDog 13:03, 25 July 2007 (UTC)


 * I agree. That method has worked very well for your extension, but I have viewed many extension pages which do not do as you have done. Perhaps adding a field with a similar meaning to offsite storage, then it could be included in the template and a standardised message (similar to the one on your page) could be put to tell people to visit the offsite link. At the moment I have been doing what you have done on your extension page, and pysically visiting the offsite extension and copying some of the info back here and adding a custom message to visit the offiste page for a more up to date version. I made this suggestion after seeing a need for it. Bouncingmolar 05:27, 30 July 2007 (UTC)

Add type: authentication
There's quite a few extensions that deal with authentication, can we add a type for these?

See Extension:Shibboleth Authentication for an example. Djcapelis 21:47, 23 July 2007 (UTC)


 * No - that's not what the type is for. We are in the process of working out a way to include the purpose(s) of an extension in the template, and once that's done then functional groupings (e.g. "authentication extensions") will be created automatically based on these new template parameter(s). --HappyDog 16:43, 24 July 2007 (UTC)


 * Okay, what is the type for? I've written  Extension:BOINC Authentication.  My next best guess is to use type 'interface'.  Is that correct?  --Eric Myers 12:25, 6 September 2007 (UTC)


 * My sense is that type identifies the technical method(s) of implementation - types are intended primarily as an aid to programmers who need help finding examples of extensions that use different kinds of entry points and programming techniques. Egfrank 07:27, 7 September 2007 (UTC)


 * So I changed the type to 'interface' and now the page seems to be categorized correctly by whatever system does that. I also explicitly added the category 'Authentication and Login', which seems to be the practice for most other auth extensions.  --Eric Myers 14:58, 7 September 2007 (UTC)


 * And I made similar changes to the Shibbolith page. --Eric Myers 15:45, 7 September 2007 (UTC)

Multiple authors
How to add multiple authors without the "author" parameter's auto link screwing up and combining multiple authors into a single author? -Eep² 02:08, 30 July 2007 (UTC)

hmmm. I've just been comma separating them and I have not been using the username field. I suppose that may cause problems for any future categories such as extension by author. Perhaps we need to add an author2 author3 field? Bouncingmolar 05:19, 30 July 2007 (UTC)


 * Yea. I tried doing something like that for extension type, but also transcluding (whatever) template:extensiontype into the switch function but it doesn't seem to work, so I undid it. Check it out if you can make it work right. -Eep² 08:53, 11 August 2007 (UTC)

Template page revision
I've added the ability to handle up to 6 types in any order and updated the documentation accordingly. In the course of this enhancement I've also made the following changes:


 * teased apart documentation and code: Documentation is now on a separate page: see Template:Extension/Doc. Hopefully this will make the code a bit easier to maintain as we go along.
 * This will also reduce the amount of material that has to be parsed when including a template and reduce the already small risk of a page with lots of transclusion being pushed over a pre-expand include limit.
 * added a "nocats" mode to the template. This lets up include it as an example on documentation pages without accidentally adding the host page to various categories. I've also used it to remove redundant listings of an extension where the author wanted the Extension template on each of his/her subpages (c.f. Extension:Google Maps)
 * added link to extension documentation when a type is unrecognized or deprecated
 * deprecated the comma delimited forms
 * fixed 3 bugs related to missing or empty attributes:
 * blank name fails to default to : now it does
 * blank types do not add extension to the unknown type category: they now do
 * blank download does not default to no link: now it does

I've run this through several tests - mostly involving alternate types and combinations of blank values. If I've missed some combos and you see a problem that isn't obvious to fix, please let me know. Egfrank 12:08, 8 September 2007 (UTC)

Proposal
As I've been spending some time recently trying to clean up the long list of extensions with invalid or missing types, I've begun to feel that there is some inconsistency in our list of types.


 * 1) I've been under the impression that "type" referred to an implementation strategy or pattern.  This works well for database/db, extended syntax, hook, link, parser function, parser, special, and variable.  Each of these has a well defined set of techniques and even articles dedicated to those techniques. I'm happy with these and categorizing articles based on these has been a relatively quick and objective process.
 * 2) Upon closer examination, there are other categories that seem to be purposes rather than patterns. I would group among these: category, data extraction, form, interface, list, media, namespace, and table.  These don't work as implementation categories because most, if not all of them, have multiple implementation patterns: at least seven of note: (i) skins and skin modifications (ii) various page action and processing hooks (iii) scripts and templates that assist in the setting of configuration variables (iv) patches to the core mediawiki code (v) wiki markup extensions of various sorts (vi) custom subclasses (vii) use of a cluster of hooks associated with one of mediawiki's classes or subsystems
 * 3) Even if we do want some element of purpose in our taxonomy, some types seem overbroad.  For example, both skin related extensions and permissions related extensions end up in type "interface".  However they serve very different purposes (work flow vs. look and feel) and are implemented using entirely different classes, hooks, and configuration variables.  An article that explained how to write permissions extensions would give little insight in how to develop a skin.
 * 4) If implementation is our focus, some important categories appear to be missing: bot toolkits and frameworks, and static maintenance/reporting scripts come to mind.  These involve very different programming patterns than parser extensions, skin extensions, or anything else involving hooks.  For one, they have the option of being run on a shut-down wiki and so don't have to be quite as careful about caching issues.
 * 5) hooks appears to suffer from diverse interpretations.  On the talk page of Extension hook registry, there seems to be some feeling that the "hook" type should be limited to functions that define their own hooks. On the other hand, a lot of people have categorized their extensions as hook exensions merely because they use hooks (defined elsewhere).
 * 6) * There is a significant difference between programming to use a hook and programming to create one. It really does seem to me that these should be separate categories
 * 7) * Hook users as a category is too broad to really have any meaning. Virtually any extension (other than a maintenance script or bot) directly or indirectly uses some sort of hook somewhere.
 * 8) the difference between database/db and data extraction' doesn't seem to be well defined.
 * 9) * Almost anything that extracts data, will, by definition be a database extension. Do we mean database/db to be something that maintains the data? Adds new database tables? It is my feeling that something that changes the database is going to raise very different administrative concerns that something that maintains or extracts data from the database and so these should be categorized separately.
 * 10) * By database/db/data extraction do we mean strictly the data stored in an SQl/Postgress database? If so, what do we do about the many extensions that provide a way to allow multi-sourcing of article content: from the dbms, the file system, even remote sources?

I don't like to raise concerns without at least offering some ideas of a solution. My response to the above is as follows:
 * 1) I do think it is helpful to have a categorization of extensions based on implementaiton techniques.  Lots of people learn by example and this makes examples easy to find.
 * 2) We now have an easy way to add multiple anythings (see type1...typeN and hook1...hookN, and Template:Foreach, so there is no reason we can't have both a purpose/usecase (usecase1...usecaseN) and type list for each extension.
 * 3) Based on the above two points, I would recommend that we:
 * 4) * deprecate category, form, interface, list, media, namespace, and table as types. If we still want the convenience of a shorthand way of specifying those purposes, we add usecase1..usecaseN parameters to the templates and use these depreciated types as part of the value set to those parameters
 * 5) * Add the interface, system, and data types needed to produce the type hierarchy below. Each type should have both a corresponding category and article describing how that type of extension is implemented and documented in our extension registry (proposed new types in red).

Egfrank 00:44, 9 September 2007 (UTC) (revised Egfrank 09:08, 9 September 2007 (UTC))
 * access - catchall for extensions that create, authenticate, grant or revoke permissions to users
 * user identity - extensions that create and delete users, and/or verify the identity of a user
 * user rights - extensions to the rights management system, e.g. changes to the way rights are assigned, apis, maintenance tools (does not include extensions that merely name rights needed to use the features of that extension).
 * interface - catchall for uncategorized extensions involving end-user interaction (exclusive of access)
 * special - extensions that define one or more special pages, i.e. extensions that subclass SpecialPage or employ older techniques of hooking into it. Note: Some special pages seem to be intended for behind-the-scenes use. Is this true? If so, does this belong under system? under both system and interface?
 * skin - extensions adding css, js, or implementing hook functions to change the look and feel of mediawiki via the skins framework.
 * page action - extensions modifying page actions via implementation of one or more non-skin hooks. Page actions would include anything that implements the action (not the permissions) for the query parameter, as well as dicussion and rating of articles.
 * mywiki - extensions that personalize mediawiki via one or more non-skin hook.
 * notify - extensions that email users, broadcast messages and provide other forms of community notification
 * locale - extension to mediawiki language/internationalization system via one or more non-skin hooks
 * parser - catchall for uncategorized parser extensions
 * tag - custom XML tag markup
 * parser function - custom parameterized markup
 * variable - custom unparameterized markup
 * link - customized ... markup
 * extended syntax - miscellaneous other types of markup
 * data - catchall for uncategorized back-end data extensions:
 * import - the back-end portion of extensions that upload various kinds of data, i.e. the filters and transformers, not the special pages and wiki markup that use them.
 * export - the back-end portion of extensions that export data from wikis in various formats.
 * include - the back-end portion of extensions that select and embed article content in non-special pages based on query parameters, e.g. Extension:DynamicPageList or Extension:LabeledSectionTransclusion and various rss extensions
 *  database/db dbschema - the back-end portion of extensions that add tables or columns to the database
 * source - extensions that support storage of articles and included content in alternate data sources - version control systems, file systems, GIS's
 * dbadmin - the back-end portion of tools for refreshing or recalculating derived data, fixing indexes, and other sorts of administrative activities.
 * system - catch all for uncategorized system extensions:
 * hook - extension that define one or more new hooks, i.e. they expand the systems customizability
 * bot - bots written for mediawiki
 * framework - api, library, or other toolkit targeted at MediaWiki extension developers
 * flavor - a bundled package of extensions meant to serve a philosophical approach to a wiki, e.g. Extension:SemanticMediaWiki or Extension:XmlWiki
 * stats - extensions that collect statistics about page or site usage or performance, e.g. Extension:FireStats
 * script - off-line administrative, data cleanup, and configuration scripts (does not include scripts dedicated solely to data or access)
 * patch - extension requiring core changes to one or more mediawiki version
 * host - integration with host - e.g. various patches to URLs, virtual host detection scripts, etc

Discussion

 * Hi. I haven't had a chance to read all of the above, but here are some points that spring to mind.  Apologies if you've already covered them or if you already know this stuff - I'll be back to look at this in more detail soon (things are a bit busy for me at the moment...)
 * You are right about the 'type' field being rubbish. It was intended to refer to implementation strategy as you suggest, but people who have not understood it have added other items to the list, and people who have understood it have not corrected (myself included).  This is partly because there was ongoing discussion and a lot of general confusion too.  See most of Category talk:Extensions for details.
 * The point of categorising extensions via the template is to help people browsing through the category tree (predominantly). There is little point in over-categorising.  That is why (for example) we removed the categorisations by author.  If we don't want to add items to a category then free text is better than structured items.
 * Your proposed categorisation scheme seems to highly specified at this point (as I say - based on quick glance).
 * In general, my thoughts are as follows:
 * Remove 'type' altogether. Introduce a new parameter 'implementation' which will largely be a 1 to 1 mapping of the current 'type' parameter but a bit clearer about what it's for.
 * Add a new parameter, 'subject' or 'function' or 'purpose' or 'feature' (all of these have been discussed and no consensus reached - the person who implements it therefore gets to choose - though my current preference is 'feature'). This should not be prescriptive.  It should be a free-form field (possibly several fields, as only one item per entry) that allows for expansion.  This will cover most of the values that you recommend removing.
 * That's my thoughts for now, but as I said I need to look at this in more detail when I get a bit more time. --HappyDog 00:27, 11 September 2007 (UTC)

Thanks so much for the feedback, especially seeing as you are busy. You seem pretty frustrated with the type parameter. In reference to your comments:
 * Overlap between implementation type and purpose: No matter what we do there will be some overlap between the values in these two fields. Not every reason for use has multiple implementation strategies and not every implementation strategy has multiple reasons for use. None the less, they are still two questions, with two different answers, addressing two different perspectives (needs requirements vs. implementation). Technically, the overlap isn't really a problem since the template is setting up the categories.  Worst case: [Category:XXX] gets added twice to the wiki text.  The main point is: we get people to ask themselves the two questions and understand that they are two questions.
 * Implementation type: many people learn best by example - a categorization by implementation type is essential for that learning strategy to work. Its current definition may be a mess, but it isn't IMHO "rubbish".
 * A better name? The idea of renaming the parameter to implementation is a good one: perhaps we should change the label. Changing the parameter name itself is a bit problematic. In MediaWiki global change is pretty much a human process and we have 200+ extensions using a parameter named "type" in their wiki code.
 * I think 'type' should be deprecated completely. However, we can do this gracefully.  Initially, we add an 'implementation' parameter to the template, literally replacing the 'type' parameter.  Then, we make the default value for 'implementation' be the otherwise unused 'type' parameter (e.g.  ) and then we add pages to Category:Extensions still using the deprecated 'type' parameter if the 'type' field is filled in.  This way, all existing pages will continue to work as before, but will be flagged as needing work (and could be listed here).  Once the cat is empty the template logic involving 'type', along with the cat, can be removed. --HappyDog 13:46, 14 September 2007 (UTC)
 * Category tree: I think the type field needs to function as more than a roadmap through the category tree. In fact, I'm not sure that's its purpose at all. People don't come to MediaWiki implicitly knowing its specific architecture (even when software architecture/development is their profession) and many people don't even have programming experience nor are they software architects - they just want to help by publishing their idea.  We need to help them back by showing them how it fits into the larger whole. This is, I think, the real purpose of the field.
 * Sure - that's the purpose of the field, but the purpose of categorising on this field is partly to make information findable via the tree, and partly to find other extensions that use similar techniques. If we don't need to the categories (which I think we do) then it should just be free text. --HappyDog 13:46, 14 September 2007 (UTC)
 * Freeform: Because some implementation patterns are specific to MediaWiki, anything that purports to capture implementation patterns needs to have clear usage guidelines. A freeform field wouldn't accomplish that at all. A prescriptive type code functions essentially as a table of contents saying "here's what's out there".  That's why each type needs to correspond (and be autolinked) to an article on that implementation pattern and we need to make sure that the template gives feedback when users use a non-standard type and links them quickly to help. Note: this feedback has already been implemented.
 * Agreed. 'implementation' should have a rigid definition (similar to 'status').  The suggestion was for the 'purpose'/'use'/'feature' field to be free-form, so if you set   it gets put in Category:Google extensions without first requiring that you lobby an admin to get 'google' added as a valid parameter value in the template. --HappyDog 13:46, 14 September 2007 (UTC)
 * Highly specified: The number of types is reflective of the complexity of MediaWiki - there are a lot of ways to customize this software. But I don't think it is overly specific. Each type corresponds to a distinct skill set and design pattern and really does need an article on its behalf discussing strategies and gotchas.  A corresponding category is not unreasonable.  The taxonomy is the end product of having gone through 200+ MediaWiki extensions and pondering their various implementation strategies (yes and even their source code).
 * Purpose/Use case field: I like the idea of a purpose/use case field, but I'm not sure what it being free-form would buy us - the description already handles the need for totally free-form input.
 * I think a mix would be better - define some purposes that are linked to well established categories and leave the rest unlinked to a category (easy to do with a parser function).  This would also help keep down over categorization by privileging the more important ones.
 * As for the name of this fields parameters/labels, my own preference is "purpose" or "usecases". Its more likely to get people focused on the question of "why do I need this?" as opposed to "how does one do this?"
 * I don't think feature will accomplish that: We already have an idea of how people are going to percieve "feature" because several extensions include feature lists - it tends to be a mix of "we're easy to install", "we use non-invasive implementation strategies", a list of implementation strategies, and sometimes purpose. Egfrank 09:24, 11 September 2007 (UTC)

Gday, I read all of the above discussion. Your proposal and category tree seems logical and well thought out, I think it would help programmers by categorising the extension architecture. I'm not a programmer, so I'm sorry if i missed the point, but it does seem exteremely specific and besides being a lot of work to implement, Who would be qualified enough to look at each extension to determine what categories they fall under. would that mean reading the code to extract the methods the authors have used?
 * Is the Purpose/Use case field, the one which categorizes the extensions by what they add to mediawiki? ie google extensions, editing extensions etc? I am very interested.. (or was) in making a category tree for the extensions to make the functions easily findable for people who maintain wikis and just want to add functionality. - Bouncingmolar 08:04, 13 September 2007 (UTC)


 * Thinking about the above - what is the point of the 'feature'/'usecase'/'subject'/'whatever' field? As far as I understand it, the point was to show the purpose of the extension in the infobox, with a link to a category containing other similar extensions.  However, if we remove the need for having this in the infobox, then using standard category links will do the same thing.  So maybe this field isn't needed at all?  Removing it from the template and using cat links instead would certainly make everyone's lives a bit easier.  Are we losing any (current, or potential future) functionality by doing this? --HappyDog 13:46, 14 September 2007 (UTC)
