 * Student: Jeroen De Dauw
 * Mentor: Brion Vibber
 * Outcome: Extensions took longer than expected, and remained uncompleted at the end of the term. The WMF decided not to fund additional development on these extensions, but there is still interest within the WMF to get this functionality working.

Improve metadata support
Improve metadata support for uploaded media in MediaWiki by displaying embedded IPTC and XMP metadata.


 * Student: Brian Wolff
 * Mentor: Chad Horohoe

"Improve and extend the Javascript for Semantic MediaWiki and some of its spinoff extensions, most notably Semantic Forms - this would include transferring over much of the Javascript to use the jQuery library, which is now becoming a MediaWiki standard."


 * Student: Sanyam Goyal
 * Mentor: Yaron Koren
 * Outcome: Work was completed as specified, and five extensions (Semantic MediaWiki, Semantic Forms, Semantic Forms Inputs, Semantic Drilldown, Semantic Result Formats) had their Javascript improved, and modified to use jQuery where appropriate.

 * Mentor: Siebrand Mazeland
 * Outcome: In active use on translatewiki.net and dozens other wikis. Niklas Laxström was active in the community before and after this project, and currently works for the Wikimedia Foundation.

Image rendering daemon
Was written in Python and designed to handle asynchronous image rendering requests.
 * "This is a proposal to fix the MediaWiki bug #4854, implementing a daemon program to render and resize images uploaded by Wikipedia users. Separating the image manipulating work from the MediaWiki application will greatly alleviate application server's load, thus improve the overall performance. The API will be designed as general as possible to accommodate the needs of other applications that also render and resize images in large quantity."


 * Student: Zhe Wu
 * Mentor: Aryeh Gregor (Simetrical)
 * Notes: Proposal was very well written, programmer obviously knew what he was doing. Major issues:
 * Was being developed on another repository. Should have been in SVN with everything else.
 * Mentored by an accomplished developer, but someone who had little interest in the subject matter
 * While the proposal was very well written, it wasn't developed with Wikimedia operations in mind. Their wants/needs should've been solicited and probably consulted during the process as well.


 * Outcome: Final status email. Since it was developed off-site, it never really received much input. It appears that none of the code was ever looked at by anyone in operations for potential deployment on WMF.

WebDAV
"I am working on an extension which provides a WebDAV / DeltaV / Subversion interface to MediaWiki articles: WebDAV"

"The extension enables articles to be browsed and edited with WebDAV or Subversion clients. When complete, it will support editing articles offline, using for example the Subclipse Eclipse IDE plugin or Emacs VC mode."


 * Student: Jack Bates
 * Mentor: ?
 * Outcome: WebDAV extension exists, but appears to be unusable.

Visual Diff
Visual diffs/2008 project - A system to provide more visually intuitive diffs, rather than lines added/removed.


 * Student: Guy Van den Broeck
 * Mentor: Brion Vibber
 * Notes: Brion was always busy, so Guy asked a lot of questions in #mediawiki.
 * Outcome: Had lots of outstanding issues - i18n, style, etc. Was a part of two releases, 1.14 and 1.15, in which it was disabled by default. Removed from trunk in r58267, and was not in 1.16 or subsequent releases. The code was used, however, as the basis for htmldiff, a non-MediaWiki PHP library that displays diffs of HTML snippets.

Special mention should also be made of another MediaWiki-related project done in 2008, but by Creative Commons and not the Wikimedia Foundation: a project to add RDFa support to Semantic MediaWiki. David McCabe was the student and Nathan Kinkade was the mentor. The code created is no longer in use.

Audio/video file recoding
The proposal: "Audio and video can instruct and inform in ways unattainable by words and still images. Currently, audio and video have only limited support and are often cumbersome to access in MediaWiki and the various projects of the Wikimedia Foundation. This project seeks to allow Wikimedia's sites to more effectively leverage the power of audio and video resources. To achieve this, a reliable and expandable system is proposed to automatically recode contributions from numerous digital a/v formats to a single, royalty and patent free compression standard. With the ability to generate such a library, Wikimedia would be poised to easily present a vast range of audio and video to their visitors using an in-browser streaming player."

 * Student: Mike Baynton
 * Mentor: Brion Vibber
 * Outcome: Code appears to have been unused by the WMF.

LiquidThreads
"Add support for structured discussion pages. Option for discussion pages to be more like message boards with threads.  Current discussion format is less than ideal (can modify others' comments, cluttered editing window, etc).  This could also include support for embedding polls in discussion pages, voting on proposals, etc.  Basically, create a minimal message board system that is tailored for use in a wiki environment (see LiquidThreads [this is a link to the page as it existed then] for some ideas in that direction)."


 * Student: David McCabe
 * Mentor: Erik Möller (?)
 * Notes: This project created the LiquidThreads extension, which had previously been only a proposal written by Erik Möller and others. David was later temporarily re-hired by the WMF in 2008 to maintain and improve the extension. See also David's GSoC project blog.


 * Outcome: Andrew Garrett, working on contract from the Foundation, spent several months in 2010 overhauling LiquidThreads entirely; almost none of the old code was kept. A project to overhaul it again was begun in 2011. Still, this could be considered a successful project: it worked, and it developed some concrete ideas that were later expanded upon in the overhaul.

Video display
No-install, in-browser display of video (and audio?) clips for Wikimedia Commons, using reasonably common Java and/or Flash components. Needs to be able to 1) play or transparently pre-convert Ogg Theora videos, 2) avoid use of patent-encumbered formats. Consider integration of Fluendo's Cortado player applet as a starting point.

Brion's talk suggested that this project would also involve creating thumbnails for video clips.


 * Student: Michael Dale
 * Mentor: Brion Vibber
 * Outcome: Michael Dale went on to work on other MediaWiki video efforts (metavid, which eventually turned into mwEmbed and finally into TimedMediaHandler, which is in testing and review before WMF deployment). Tim Starling did the final integration of the Cortado applet and Ogg parsing as part of the OggHandler extension, which currently supports video functionality on Wikimedia Commons. Michael Dale came back to work with the Foundation in late 2008 on a few different projects with support from Kaltura, mentored a student in 2009, and is still active in developing Wikimedia technologies.
