I lead platform work
<https://github.com/creativecommons/platform-initiative> at Creative
Commons. As part of that work, we are exploring the potential of a standard
field in EXIF that could make attribution and license info more sticky
across the web. We are currently in the research phase -- talking to major
image hosting platforms (and platforms that read and ingest images) about
what kinds of image metadata they read and retain. Zhou and his engineering
team at Wikimedia directed me to this list as I am seeking feedback from
the Wikimedia community.
Ultimately, we want to make it easier for platforms to display provenance
and license info -- increase the likelihood that when a user lands on an
image, they know who created it and what license to use it under. For
example, images from Wikimedia Commons may get tweeted, but the image
metadata is not retained in tweets. How can we work with platforms to use
the same metadata standard so that info can be retained across them?
Since we are just in the research phase now, I welcome your thoughts on
Wikimedia Commons' and Wikipedia's own uses of image metadata. Specifically:
1. The most common image metadata standards we know about are EXIF and
XMP. Which does Wikimedia primarily read and retain? Are there others that
are more widely used?
2. Which standard does Wikimedia prefer? What would be easiest to
implement? for Wikimedia, but also for the platforms that Wikimedia
interfaces with. Aka, what are the pros and cons of each?
Lastly, welcome any general thoughts about the feasibility and need for
such a project.

Observations on the upload and playback of
1. I'm impressed by how much the video compressed, down to 1.97 Mbps on
2. I had multiple problems when uploading this file in WebM/VP9 format.
Firefox crashed every time I tried to use the upload wizard with chunked
uploads enabled. IE was successful after I changed my chunked upload
setting to 1 simultaneous upload.
3. The upload progress bar was very inaccurate on Firefox. On IE, the bar
seemed to indicate the upload progress of the 5MB chunks rather than the
progress of the whole video.
4. The automated transcoding process to multiple formats on Commons is
nice, although there was a notable decrease in audio quality on the OGV
file that I downloaded.
5. On playback of the video in ENWP by clicking the thumbnail which results
in the video popup window, I think it would be good to make the option to
fullscreen the video more obvious to the viewer inside of the popup window.
* Do you have small, self-contained, "easy" bugs you'd love to get fixed?
(Also see https://www.mediawiki.org/wiki/Annoying_little_bugs )
* Does your documentation need improvements?
* Do your old bugs welcome some testing?
* Does your user interface have some small design issues?
* Does the Outreachy/GSoC project you finished welcome small tweaks?
* Would you enjoy helping someone port your template to Lua?
* Does your gadget use some deprecated API calls?
* Do you have some tasks that welcome some research?
Google Code-In (GCI) will take place again in Dec+Jan: a contest for
13-17 year old students to provide small contributions to free
Wikimedia will apply again to take part in GCI. The more tasks we can
offer the likelier the changes Wikimedia will get accepted.
Unsure about quality of contributions and effort?
Read about tgr's post about Multimedia achievements in GCI 2014:
* Add the project "GCI2015" + a comment to Phabricator tasks you'd mentor.
* Tasks are welcome in five areas: Code; Outreach/Research;
Documentation/Training; Quality Assurance; User Interface.
* Make sure the task description provides pointers to help the student.
* Add yourself to the table of mentors on the wikipage.
* "Beginner tasks" (<30 min for an experienced contributor) also welcome.
* "Generic" tasks also welcome (e.g. "Fix two user interface messages from
the "Blocked By" list in https://phabricator.wikimedia.org/T40638 ").
For all information, check
"Easy" Multimedia tasks (are they still valid? are there more?):
Can you imagine providing a helping hand to someone fixing tasks?
Please ask if you have questions!
