2011-12-31
<section begin=2011-12-31/>Ian Baker and Neil Kandalgaonkar completed the review of all the code, including the transcoding part. They started to plan a test plan and a deployment to Wikimedia Labs. Aaron Schulz merged the FileBackend branch into, and Tim Starling started to review the code. Aaron, Ben Hartshorne, Ariel Glenn discussed sharding the Swift containers at the MediaWiki level, and Aaron started to implement it.<section end=2011-12-31/>

2012-01-03
<section begin=2012-01-03/>FileBackend code has been merged, and has gone through preliminary review with Tim. Some fixes still being made in trunk. MediaWiki-level sharding of containers is currently being implemented by Aaron.<section end=2012-01-03/>

2012-01-05
<section begin=2012-01-05/>Container sharding added FileBackend class. Aaron has a testwiki running of the swift test cluster and SwiftFilebackend.<section end=2012-01-05/>

2012-01-19
<section begin=2012-01-19/>Aaron continues to make performance improvements and minor fixes to the Swift backend and FileOp classes.<section end=2012-01-19/>

2012-01-31
<section begin=2012-01-31/>The beginnings of a TimedMediaHandler test setup were put into place in Wikimedia Labs, including video transcoding infrastructure, at http://commons.wikimedia.beta.wmflabs.org. Work on this test setup will continue in February, with the goal to begin executing the test plan in preparation for deployment. Aaron Schulz added container sharding to FileBackend, and continued to make performance improvements and fixes. The Swift back-end now passes all unit tests; the code is being reviewed and cleaned up. Some of Aaron's code for purging thumbnails will be backported to MediaWiki 1.18. Ben Hartshorne has prepared interim hardware for production deployment, which will begin the week of February 6.<section end=2012-01-31/>

2012-02-29
<section begin=2012-02-29/>Michael Dale and Jan Gerber continued testing and improving the TimedMediaHandler extension setup in Wikimedia Labs (inside the Wikimedia Commons deployment-prep wiki). It will be tested there before it is prepared for deployment to production, with the required transcoding infrastructure. After more polish by Aaron Schulz and a February deployment of SwiftMedia and Swift, Swift is now serving 100% of thumbnails on Wikimedia Commons (engineering report).<section end=2012-02-29/>

2012-03-31
<section begin=2012-03-31/>Michael Dale and Jan Gerber have TimedMediaHandler set up on beta. It is running into issues related to the Labs beta setup that are preventing the test plan from being run. Labs and QA leads are working with them to get to the point where testing can be run. QA support has been lined up. Swift is deployed for thumbnails. There are still some corrupted thumbnails in the Squid cache, but all known issues with new thumbnail corruption have been resolved. Work is underway to test and deploy Swift for original images, with work scheduled to complete in late May.<section end=2012-03-31/>

2012-04-monthly
<section begin=2012-04-monthly/>Michael Dale and Jan Gerber are looking into transcoding bugs in TimedMediaHandler. A lot of issues on beta are hardware- or configuration-related (virtual instances are running out of resources) and more hardware will be going online soon. In the meantime, the client-side playback parts of the test plan are being run by Chris McMahon and Tauhida Parveen. Ben Hartshorne and Leslie Carr have been running a script to clean up corrupted thumbnails in Swift. Aaron Schulz has been fixing bugs, and is now focusing on adding concurrent file operation support to PHP cloudfiles (the PHP interface to Swift) and to MediaWiki's FileBackend code. This should help alleviate .<section end=2012-04-monthly/>

2012-05-02
<section begin=2012-05-02/> In QA: Tauhida is hacking through the test plan. Uploading (wizard) is taking a while but not timing out (~14 min/90MB). Bug List.<section end=2012-05-02/>

2012-05-23
<section begin=2012-05-23/>As of 5/18, Antoine updated beta config to closer track master branch (production) of Mediawiki via git/puppet. Video can be uploaded via UploadWizard and queued by TMH. Queue processing is blocking on the ffmpeg2theora missing from the configuration. <section end=2012-05-23/>

2012-05-monthly
<section begin="2012-05-monthly"/>Antoine Musso and the Labs team have unblocked the deployment prep issues; Labs is now closely tracking production MediaWiki. Most of the features (upload, play, full screen, etc.) are now in testing, and upload seems to be faster than before as well. Aaron Schulz and Ben Hartshorne deployed a new version of the thumbnail handler to Commons, test, test2, and mediawiki.org, that uses our Swift FileBackend code. It should provide us with useful production testing prior to using Swift FileBackend for handling original files. Cleanup of corrupted thumbnails is now finished. Aaron deployed a SiteStats fix that should make uploads much faster and fix some timeout problems. Ben and Aaron will also roll out the FileBackend-based thumbnail handler to the rest of the wikis.<section end="2012-05-monthly"/>

2012-06-22
<section begin="2012-06-22"/>Ben is installing SSDs for use in storing the object listing database, in hopes that having faster storage will result in faster purge times (fixing ). All work for deploying Swift for storage of originals is on hold until we fix the object listing performance problems.<section end="2012-06-22"/>

2012-06-monthly
<section begin="2012-06-monthly"/>Development on TimedMediaHandler has been put on pause until Jan Gerber comes into San Francisco late July for the final push. Ben Hartshorne is installing SSDs for use in storing the object listing database, in hopes that having faster storage will result in faster purge times (fixing ), which we hoped to complete in June, but which is stretching into July. All work for deploying Swift for storage of original images is on hold until we fix the object listing performance problems.<section end="2012-06-monthly"/>

2012-07-18
<section begin="2012-07-18"/>Jan Gerber is in San Francisco, currently working on fixing up the transcoding, and ensuring interoperability with SwiftMedia <section end="2012-07-18"/>

2012-07-27
<section begin="2012-07-27"/>Aaron has the process of migrating image originals into Swift well underway. Commons is done (barring a few minor problems to investigate in the logs). The rest of the wikis are in various stages of progress. Meanwhile, there's also a minor architectural change (MultiWrite backend) that will be deployed next week, which is a necessary prerequisite to serving/storing originals in Swift. Thumb handling changes may also be deployed next week during the scheduled window (currently slated for Wednesday, August 1)<section end="2012-07-27"/>

2012-07-monthly
<section begin="2012-07-monthly"/>Jan Gerber is in San Francisco, currently working on fixing up the transcoding, and ensuring interoperability with SwiftMedia, working with Michael Dale. On July 31, Aaron Schulz, Jan, and Michael deployed the TimedMediaHandler extension to test2. Aaron Schulz is in the process of migrating image originals into Swift. Commons is completed (barring a few minor problems to investigate in the logs), and the rest of the wikis are in various stages of progress. Meanwhile, there's also a minor architectural change (MultiWrite backend) that will be deployed soon, which is a necessary prerequisite to serving/storing originals in Swift.<section end="2012-07-monthly"/>

2012-08-30
<section begin="2012-08-30"/>All Wikis are using a multi-write backend to push writes to both Swift and NFS. This has been running for several weeks. All reads of upload originals are served from Swift, including upload.wikimedia.org. The Math and Timeline extensions will be migrated to Swift soon.<section end="2012-08-30"/>

2012-08-monthly
<section begin="2012-08-monthly"/>In August we concentrated on testing on the testwiki, and found some issues that need addressing. The project is on hold for now, but we expect to resume in September. All Wikimedia sites are now using Swift as the primary storage mechanism for multimedia files such as images (both original images as well as image thumbnails). We continue to write images to our old NFS server as well, though we plan to turn this off in September. Some specialized extensions still use the old NFS server, such as the Math and Timeline extensions. These will be migrated to Swift soon (tentatively in September).<section end="2012-08-monthly"/>

2012-09-monthly
<section begin="2012-09-monthly"/>The test deployment and testing are tracked in ; Michael Dale is following up and we are hoping to fix the last issues to deploy TMH to Wikimedia sites soon. The Math, EZTimeline, and ConfirmEdit extensions were updated to be able to use Swift-based storage, and all but ConfirmEdit are now using Swift in production. We weren't able to turn off the old NFS server (ms7) as we originally planned, due to hardware issues on our Swift nodes and unanticipated issues with Swift-based replication to our Ashburn data center. We are very nearly out of space on ms7, so our new plan is to back our media storage onto a newer NFS system.<section end="2012-09-monthly"/>

2012-10-monthly
<section begin="2012-10-monthly"/>The last of the blocking bugs have been resolved, so we now plan to deploy TimedMediaHandler to English Wikipedia on October 31 at 16:00 UTC. Further deployments will follow, tentatively the week of November 5. At the beginning of October, we had our new Swift distributed file storage cluster in production, with copies of all original media also being made to an NFS server (ms7) that was destined to fill up in the month of October. Our original plan was to shut off copying to ms7 and rely solely on the Swift cluster. Because of hardware issues with the Swift cluster, we decided we couldn't afford to switch off the copying of files to an NFS backup. We migrated the contents of ms7 over to a much larger NFS server (nas1), and configured nas1 to be the new live backup for images. We plan to remain in this configuration for the foreseeable future as we stabilize our distributed file store.<section end="2012-10-monthly"/>

2012-11-01
<section begin="2012-11-01"/>We have now deployed TimedMediaHandler to English Wikipedia (see some examples of videos). We plan to deploy to all other wikis but commons on Monday, November 5 at 18:00 UTC, and then deploy to Commons on Wednesday, November 7 at 17:00 UTC.<section end="2012-11-01"/>

2012-11-07
<section begin="2012-11-07"/>We have now deployed TimedMediaHandler to all wikis. We deployed to most wikis Monday, November 5, and then most recently to Commons on Wednesday, November 7 at 17:05 UTC.<section end="2012-11-07"/>

2012-11-28
<section begin="2012-11-28"/>Thumnails (and math/timeline files) are now written to nas1 and swift. More improvements have been made to FileBackend to avoid extra HEAD requests for 404s. Webm thumbnails use temp swift URLs to support range requests. Feature requests and bugs reports are filed against ceph as MW takes advantage of other swift features.<section end="2012-11-28"/>

2012-11-monthly
<section begin="2012-11-monthly"/>We have deployed TimedMediaHandler to all wikis. Jan Gerber and Michael Dale continue to fix bugs. Jan Gerber and Aaron Schulz are working on an improved file upload mechanism in UploadWizard to make larger file uploads more practical. Thumbnails (and math/timeline files) are now written to nas1 and Swift. More improvements have been made to FileBackend to avoid extra HEAD requests for 404 errors. Webm thumbnails use temporary Swift URLs to support range requests. Feature requests and bugs reports are filed against Ceph as MediaWiki takes advantage of other Swift features.<section end="2012-11-monthly"/>

2012-12-monthly
<section begin="2012-12-monthly"/>Jan Gerber continued to refine the TimedMediaHandler extension, making the transcoding steps more robust. Captchas are ready to be served from Swift. They previously were for several days, but the configuration had to be reverted to due random errors from Swift. A new set of captchas are being tweaked for readability and are served from Swift on the test wikis. Captchas are one of the last NFS dependencies.<section end="2012-12-monthly"/>

2013-01-monthly
<section begin="2013-01-monthly"/>Jan Gerber continues bugfixing and refining TimedMediaHandler, mainly focusing on operational improvements to make more efficient use of our server infrastructure. NFS for uploads/thumbnails has been unmounted from all Apache servers and the NFS back-end configuration was removed from MediaWiki; all files now only use Swift. A workaround has been added for the Swift back-end class when used with Ceph, so that temporary URLs can be used (for making video thumbnails for example). A Python script to copy files into Ceph has been run and is being worked on. Various issues have been reported in Ceph's bug tracker and are being looked at by the developers.<section end="2013-01-monthly"/>

2013-02-monthly
<section begin="2013-02-monthly"/>Jan Gerber continues to work part-time for the WMF to fix multimedia bugs. Fixes include better support for FLAC files and better support for metadata display in small embedded players. Nearly all files have been copied from Swift (in Tampa) to Ceph (in Ashburn). Further scripts will be run to synchronize the Ceph files to account for deletions and updates to files. The Varnish configuration to handle URL rewriting (to take the place of rewrite.py in swift) is already coded, though not yet in use.<section end="2013-02-monthly"/>

2013-03-06
<section begin="2013-03-06"/>Transcoded videos have been moved to there own container so the file backend and caching layer can make improvements specific to videos. Improvements for smaller embeds and getting rid of any gM call for messages.<section end="2013-03-06"/>

2013-03-12
<section begin="2013-03-12"/>An API to rotate images was merged into core <section end="2013-03-12"/>

2013-03-monthly
<section begin="2013-03-monthly"/>Mostly bugfixing this month, as well as hiring for the two multimedia positions. Jan Gerber finished work on an API to rotate images, which needs a little site configuration work to get deployed. Transcoded videos have been moved to their own container in the Swift filesystem in anticipation of video-specific optimizations. Jan also improved the user interface in cases where an embedded media player is too small to display credits and player controls. TimedMediaHandler was extended so that other MediaWiki extensions can render player elements using PHP. The Score extension can now use TimedMediaHandler or OggHandler to render the audio player (see ), which puts the Score extension one step closer to deployment and music staves one step closer to generation and display in wiki pages (see ).<section end="2013-03-monthly"/>

2013-03-29
<section begin="2013-03-29"/>TimedMediaHandler was extended so that other extensions can render player elements from PHP. The Score extension can now use TimedMediaHandler or OggHandler to render the audio player. <section end="2013-03-29"/>

2013-04-17
<section begin="2013-04-17"/>Score extension is now working on test2 and is ready for deployment. Some videos that were uploaded as Ogg Theora had problems being transcoded into WebM, so we upgraded our transcoder (libvpx) and that has been deployed; failed transcoddes need to be queued again, which will happen soon. VipsScaler will be deployed after a new version of vips library is upgraded on our image scalers .<section end="2013-04-17"/>

2013-04-monthly
<section begin="2013-04-monthly"/>Differently-sized video thumbnails now only require one reference thumbnail (for the time position) to be generated. This helps to avoid expensive decoding to derive thumbnails. The Score extension was deployed on April 22nd. It allows users to create and document musical scores on Wikimedia sites.<section end="2013-04-monthly"/>

2013-05-monthly
<section begin="2013-05-monthly"/>After deploying Score in April, various performance improvements and fixes were merged in May. To improve scaling of large images, the VipsScaler extension was prepared on the cluster and is ready for deployment in the next weeks. TimedMediaHandler had various bug fixes and the libraries used to encode WebM videos were updated to improve quality and address encoding issues.<section end="2013-05-monthly"/>

2013-06-monthly
<section begin="2013-06-monthly"/>In June, we started expanding our multimedia team: Fabrice Florin joined as product manager, and Brian Wolff began a summer contract as software engineer. We started work on improving the display of images in galleries and are now planning our next development steps in consultation with community members. Some of the first features under consideration include file curation and feedback tools, as well as media viewers, new video formats and other platform improvements, to be prioritized based on user feedback and technical feasibility. We are also recruiting for two more positions: a multimedia systems engineer and a senior software engineer. Please spread the word about this unique opportunity to create a richer multimedia experience for Wikipedia and MediaWiki sites!<section end="2013-06-monthly"/>

2013-07-monthly
<section begin="2013-07-monthly"/>In July, we continued to expand our multimedia team: Mark Holmquist joined as front-end software developer, working with product manager Fabrice Florin and engineering director Rob Lanphier, as well as contractors Brian Wolff and Jan Gerber. We prepared a first multimedia plan for the coming year and discussed our goals with community members in two separate events: a multimedia roundtable and an IRC chat. Based on community feedback, we identified five main areas of activity 2013-2014: improving the viewing experience and upload pipeline in the first half of the year, then focusing on file curation, discovery and placement in articles for the second half of the year. Our overall goals for this year are to increase both the number of contributions and files used in Wikipedia articles. For now, we have started work on a new media viewer to display images in larger size when you click on a thumbnail, as well as display file information and a full-screen viewing option, right on the same page. We plan to have a first version of that feature next month, and will be testing it as part of a beta experiment on a few pilot sites. We will also be hosting more community planning discussions, such as this multimedia roundtable at Wikimania 2013. To participate in these discussions and keep up with our work, we invite you to join this new multimedia mailing list. Last but not least, we are also recruiting for two more positions for our team: a multimedia systems engineer and a senior software engineer. Please spread the word about this unique opportunity to create a richer multimedia experience for Wikipedia and MediaWiki sites! <section end="2013-07-monthly"/>

2013-08-monthly
<section begin="2013-08-monthly"/>In August, we continued to expand our multimedia team: Bryan Davis joined us as senior platform engineer, working with product manager Fabrice Florin, front-end engineer Mark Holmquist and engineering director Rob Lanphier. We discussed multimedia plans and new feature ideas with community members in two separate events: a multimedia roundtable at Wikimania 2013 and an IRC chat, and updated our multimedia plan for the coming year based on their feedback (see slides). Summer contractor Brian Wolff completed the development of new gallery tags to support more appealing layouts for thumbnails, while Jan Gerber made improvements to the Score and TimeMediaHandler extensions. Mark Holmquist started development on the Media Viewer, based on designs by May Tee-Galloway and Jared Zimmerman; this new tool will display images in larger size when clicking on article thumbnails, as well as display file information and a full-screen viewing option, right on the same page. We aim to test a first version of this tool as part of a beta experiment on a few pilot sites in coming weeks. To discuss these features and keep up with our work, we invite you to join this new multimedia mailing list.

2013-09-monthly
<section begin="2013-09-monthly"/>In September, we continued to expand our multimedia team and updated our multimedia plan for the coming year (see slides). Mark Holmquist continued development on the Media Viewer to improve the image viewing experience, based on designs by May Tee-Galloway and Jared Zimmerman. We also made good progress on the Beta Features project, which will invite users to test, give feedback, and use a range of new features in real-world settings. We aim to have first beta versions of both products ready by the end of the October. New employee Bryan Davis started work on several multimedia platform bugs, and Summer contractor Jan Gerber completed his work on the TimedMediaHandler extension.

Last but not least, we are also recruiting for a senior software engineer position on our team.<section end="2013-09-monthly"/>

2013-10-monthly
<section begin="2013-10-monthly"/>In October, we continued to expand our multimedia team and hired Gergő Tisza as software engineer. Mark Holmquist worked with Gergő to develop a first beta version of the Media Viewer, which displays images in larger size or full screen; this work was based on designs by Pau Giner, May Tee-Galloway and Jared Zimmerman. We also completed development on the Beta Features program, which invites users to try out new features before they are released for everyone. A first version of both products is now ready for testing by logged in users on MediaWiki.org (to try new features, click on the small 'Beta' link next to your 'Preferences'). We plan to release the Beta Features program in coming days to Wikimedia Commons and Meta-Wiki, then to all wikis worldwide at the end of November. Fabrice Florin managed the development of both projects, and updated our multimedia plans to prepare for roundtable discussions with community members next month. Bryan Davis started work on improving the thumbnail pipeline and guided the development of an upcoming GLAM Toolset for batch uploads by museum curators. To discuss these features and keep up with our work, we invite you to join the new multimedia mailing list. We are also recruiting for a senior software engineer position on our team.<section end="2013-10-monthly"/>

2013-11-monthly
<section begin="2013-11-monthly"/>In November, Mark Holmquist and Gergő Tisza developed a second beta version of the Media Viewer, based on new designs by Pau Giner. For a more immersive experience, this next version displays larger images, as shown in the demo. We also released Beta Features on all Wikimedia wikis, where it is already used by thousands of users. This experimental program invites users to try out new features before they are released widely, then give feedback to developers. To use Beta Features, click on the small 'Beta' link next to your 'Preferences' on your site, or test the latest version on MediaWiki.org. Fabrice Florin managed product development, led the creation of the Multimedia Vision 2016 (with Pau Giner), hosted roundtable discussions and updated the team's multimedia plans, based on community and team feedback. Bryan Davis, Aaron Schulz and Chris Steipp reviewed new code for the upcoming GLAM Toolset for batch uploads by museum curators.

To discuss these features and keep up with our work, we invite you to join the multimedia mailing list. We are also recruiting for a senior software engineer position on our team.<section end="2013-11-monthly"/>

2013-12-monthly
<section begin="2013-12-monthly"/>In December, Mark Holmquist and Gergő Tisza updated the beta version of the Media Viewer, based on new designs by Pau Giner. This new version now features next and previous arrows, as well as faster image load and an enhanced metadata panel, as shown on this demo page. Fabrice Florin managed product development, spearheaded the team's Multimedia Quarterly Review meeting, hosted more roundtable discussions and presented a Multimedia Vision 2016 to get more community feedback about our goals, with help from volunteer Aaron Arcos. Bryan Davis, Aaron Schulz and other team members helped Dan Entous and David Haskiya release a first version of the GLAM Toolset for batch uploads by museum curators. We also started work on fixing bugs for the Upload Wizard, which we'll aim to improve as our primary focus this quarter. Last but not least, we are delighted to welcome Gilles Dubuc, who is joining our multimedia team as senior software engineer. To discuss these features and keep up with our work, we invite you to join the multimedia mailing list.<section end="2013-12-monthly"/>

2014-01-monthly
<section begin="2014-01-monthly"/>In January, the multimedia team focused on developing the Media Viewer and planning our next projects for the year. Gilles Dubuc, Mark Holmquist, Gergo Tisza and volunteer Aaron Arcos implemented a number of improvements to the beta version of the Media Viewer. Some of the features we created or improved include: faster image load, a full-screen mode, better navigation between files, an expanded meta-data panel with caption, location, categories and other information. We invite you to test the new UI features on this beta site; faster image load can be tested on this MediaWiki.org page (In both cases, you need to create an account, then click on 'Beta' in your personal menu and enable Media Viewer.) Pau Giner also designed in the upcoming v0.3 version of Media Viewer, based on team recommendations. Fabrice Florin started a community discussion of our team's Multimedia Vision for 2016, which proposes a range of improvements to help engage users and support productive collaborations in coming years (more comments welcome). We also planned our work for this quarter's release, which focuses on Media Viewer through the end of March, and started planning our next big priorities for the rest of the year: UploadWizard and Structured Data on Commons. Lastly, we started a Request for Comments about possible support for the MP4 video standard: we invite you to participate in this discussion, which is due to end in mid-February; we will plan our next steps for video based on community feedback for this RfC. To discuss these projects and keep up with our work, we invite you to join the multimedia mailing list. <section end="2014-01-monthly"/>

2014-02-monthly
<section begin="2014-02-monthly"/> In February, the multimedia team continued to focus on Media Viewer v0.2, getting it ready for a wider release next quarter. Gilles Dubuc, Mark Holmquist, Gergő Tisza and Aaron Arcos released a variety of new features, such as: permissions, file usage, pre-loading of images, previews during load and an improved full-screen experience. We also started development on a better 'Use this file' panel, including share, embed and download features. Pau Giner designed this panel, as well as a new Zoom feature for a future version v0.3 of Media Viewer. We invite you to test the latest version (see the testing tips) and share your feedback. Fabrice Florin managed product development for Media Viewer and prepared the release plan for a gradual deployment of Media Viewer out of beta in coming months, based on the team's latest development goals. We also hosted an IRC chat to discuss Media Viewer with the rest of the community and plan our next steps together. Lastly, the video RfC we started last month was closed with a community recommendation to not support the proprietary MP4 video format on our sites; as a result, we will only support open video formats like WebM and Ogg in the next version (v0.3) of Media Viewer. For more updates, we invite you to join the multimedia mailing list.<section end="2014-02-monthly"/>

2014-03-monthly
<section begin="2014-03-monthly"/> In March, the multimedia team’s main project was Media Viewer v0.2, as we completed final features for the tool's upcoming release next quarter. Gilles Dubuc, Mark Holmquist, Gergő Tisza and Aaron Arcos developed a number of new features, including: share, embed, download, opt-out preference,file page link and feedback link, based on designs by Pau Giner. We invite you to test the latest version (see the testing tips) and share your feedback. Fabrice Florin coached the multimedia team as product manager and hosted several planning and review meetings, including a cycle planning meeting (leading to the next cycle plan) and the Multimedia Quarterly Review Meeting for the first quarter of 2014, which summarizes our progress and next steps for coming work (see slides). He also worked with Keegan Peterzell to engage community members for the gradual release of Media Viewer, to be enabled by default on a number of pilot sites next month, then deployed widely to all wikis a few weeks later.

2014-04-monthly
<section begin="2014-04-monthly"/> In April, the multimedia team released Media Viewer v0.2 on 14 pilot sites, in preparation for a wider deployment next month: overall response has been favorable so far, and a growing majority of survey respondents are finding this new multimedia browser useful. Gilles Dubuc, Mark Holmquist, Gergő Tisza and Aaron Arcos developed final features for this release, as described on this release's wall, based on designs by Pau Giner. We also developed a set of metrics dashboards to track global activity, image load and network performance, as well as local metrics dashboards for selected sites: first results show a decline in image load time, and suggest that Media Viewer loads faster than file description pages. We invite you to test the latest version of Media Viewer (see these testing tips) and share your feedback. Fabrice Florin led product planning and management, hosting a planning meeting for our next development cycle (leading to a wall of tasks): for the next six weeks, we plan to divide our time between Media Viewer (e.g. serious bugs, basic zoom feature), Technical Debt (e.g. image scalers) and Upload Wizard. Keegan Peterzell and Fabrice announced the gradual release of Media Viewer on dozens of wiki sites, starting new discussions in collaboration with our community partners, as well as launching surveys in multiple languages to get reader feedback about this tool.

2014-05-monthly
<section begin="2014-05-monthly"/> In May, the multimedia team released Media Viewer v0.2 on more large wikis (Dutch, French, Italian, Japanese, Portuguese, Spanish and Russian Wikipedias), with over 10 million image views daily. This multimedia browser has been well received: 70% of survey respondents find this tool useful; based on this favorable feedback, we plan to deploy Media Viewer on all wikis in June. Gilles Dubuc, Mark Holmquist, and Gergő Tisza fixed more bugs and features during this development cycle, with design help from Pau Giner.

The team has switched its focus to new projects, starting with the UploadWizard, our main user-facing feature this year: this month, we collected metrics, reviewed user feedback, created new designs, fixed bugs and refactored code as part of a major upgrade of this important contribution tool. We also allocated a third of our time to technical debt and bug fixes for other multimedia tools, with an initial focus on improving image scalers, GWToolset and TimedMediaHandler.

Fabrice Florin managed product development, hosting an annual planning meeting to define our goals for 2014−15: this year, we aim to engage more users to contribute media to our sites through tools like UploadWizard, while implementing structured data on Commons and continuing to address our technical debt and fix critical bugs. Keegan Peterzell and Fabrice also continued to engage our community partners throughout the release of Media Viewer. We are planning new discussions in coming weeks to improve our plans together. For join these conversations and keep up with our work, we invite you to subscribe to the multimedia mailing list.<section end="2014-05-monthly"/>

2014-06-monthly
<section begin="2014-06-monthly"/>In June, the multimedia team released Media Viewer v0.2 on all wikis hosted by WMF, with over 20 million image views per day on sites we track. Global feedback was generally positive and helped surface a range of issues, many of which were addressed quickly. Based on this feedback, Gilles Dubuc, Mark Holmquist, and Gergő Tisza developed a number of new features, with designs by Pau Giner: view images in full resolution, view images in different sizes, show more image information, edit image file pages, as well as easy disable tools for anons and editors.

This month, we started working on the Structured Data project with the Wikidata team, to implement machine-readable data on Wikimedia Commons. We are now in a planning phase and aim to start development in the fall. We ramped up our work on UploadWizard, reviewed user feedback, collected metrics, fixed bugs and started code refactoring, with the help of contract engineer Neil Kandalgaonkar. We also kept working on technical debt and bug fixes for other multimedia tools, such as image scalers, GWToolset and TimedMediaHandler, with the help of summer contractor Brian Wolff.

As product manager, Fabrice Florin helped plan our next steps, hosting this planning meeting and other discussions of our development goals -- and led an extensive review of user feedback for Media Viewer and Upload Wizard with new researcher Abbey Ripstra. Community liaison Keegan Peterzell introduced Media Viewer and responded to user comments throughout the product's worldwide release.
