[ANN] Experimental Wikimedia Commons RDF extraction with DBpedia

Hi everybody,

We are happy to announce an experimental RDF dump of the Wikimedia Commons. A complete first draft is now
available online at http://nl.dbpedia.org/downloads/commonswiki/20140705/, and will be
eventually accesible from http://commons.dbpedia.org. A small sample dataset, which may be easier to
browse, is available on Github at https://github.com/gaurav/commons-extraction/tree/master/commonswiki/20140101

The following datasets showcases some of the improvements that we’ve been working on over the last two months:
 - File information (*-file-information.*) is a completely new dataset that contains information on the
files in the Commons, including file and thumbnail URLs, file extensions, file type classes and MIME types.
 - DBpedia’s Mappings Extractor (*-mappingbased-properties.*) uses templates stored on the Mapping
server (http://mappings.dbpedia.org/) to create RDF for information-rich templates. This system
still has some important limitations, such as not being able to process process embedded templates (e.g.
license templates inside {{Information}}), but top-level templates are completely configurable. The
existing mappings are available at http://mappings.dbpedia.org/index.php/Mapping_commons
 - This includes 363 license templates that indicate licensing for Commons files under public domain,
Creative Commons and other open access licenses. These were created by bots and still require
verification before use. They are listed at http://mappings.dbpedia.org/index.php/Category:Commons_media_license
 - The DBpedia Geoextractor (*-geo-coordinates.*) now extracts geographical coordinates from Commons
files using the {{Location}} template.
 - The DBpedia SKOS Extractor (*-skos-categories.*) now identifies relationships between Commons
categories, building a SKOS-based description of the entire Commons category tree.

Please have a look and let us know what you think. We’ll be working on a number of open tasks over the next
three weeks, listed at https://github.com/gaurav/extraction-framework/issues?state=open -- if
you see something wrong with what we’ve done above, or have an issue you’d particularly like us to
tackle, please report it there or drop me an e-mail!

This work is sponsored by the Google Summer of Code program

Preliminary work on install-free audio/video playback in Safari and IE

Commons uses the freely-licensed Ogg and WebM formats for media files; unfortunately these are not supported by default in Safari and Internet Explorer, as Apple and Microsoft favor a competing format. Manual codec installation goes against modern user expectations, and isn't possible in some environments.

I've spent some research time working on ogv.js, which uses Mozilla's emscripten and Adobe's CrossBridge to cross-compile the Ogg Vorbis and Theora codecs to JavaScript and Flash. This allows decoding and playing Ogg media in the browser without additional software installation.


Here's a live demo wiki with ogv.js embedded into the player widget:
http://ogvjs-testing.wmflabs.org/wiki/Demo

On Firefox, Chrome, or Opera you'll continue to get native Ogg or WebM playback; on Safari 6.1/7 and iOS 7 Mobile Safari you get the JavaScript Ogg player, and on IE 9/10/11 you get the Flash Ogg player. (Microsoft lists Web Audio as "in development" for future IE versions, which will enable use of the pure JS version there as well.)


This is very much a work in progress, but I'm pretty confident this is something we can deploy later this year to get basic A/V playback to "just work" for another chunk of our users.

I'll be presenting some further status updates & related topics at my Wikimania talk.

Note that the Flash code used for IE is entirely open-source and uses none of the proprietary multimedia codecs built into Flash. I consider this a delightfully subversive use of Flash, and it would please me no end to get it deployed on Wikimedia. :)

People not able to attend Wikimania

Hoi.
I am very sorry to have learned that Amir Ladsgroup may not enter the United Kingdom for Wikimania. As you may know, Amir is crucial to the development of the Pywikibot software.

Not having him present is awful. Obviously other people can present but it is not the same as Amir presenting.. It may be possible to have him present by Skype or Hangout.

Would this be an option ?

For your information the amount of effort that has gone in acquiring a visa for Amir has been huge. A big thank you to all the people involved. It is sad that all the effort did not produce the result we all wished for.
Thanks,
      GerardM

New new photo page design on Flickr

Yesterday a number of yahoo.uservoice.com highly voted requests were
closed on the basis that a redesign of the redesign has fixed them. It
seems the update is only available in English and I don't find a way to
change interface language (!), can someone who sees it please give some
insight?

Dear Flickr members,

We recently launched a new photo page towards the end of June. Because
of the feedback from you, we’re moving the photo page in a direction
that more closely resembles previous iterations of the product, but with
contemporary design and the new framework that delivers photos so much
faster than before.

These are the advantages of the new photo page:
*Moved the photo information back, so now it appears below the photo.
*The comments have been moved back below the photo as well.
*The text is now black on a white background.

If you have any feedback regarding the new photo page, positive or
negative, please feel free to submit it using a new thread.

Please be aware that we are actively listening to feedback from our
users to improve Flickr and your user experience.

Support for Chemical table files

As of now, images of structural formulas have to be created using third
party software and converting the output to SVG or PNG. With MolHandler
we aim for a solution capable accepting and rendering chemical markup
files and providing a web-interface for easily creating, modifying and
re-mixing formula files. This does not only make re-using existing
structures easier and simplifies creation of structures, moreover it
allows Wikis to adopt a unified style for rendering these structures,
makes structures searchable (sub-structure search) allows pulling,
pushing and verifying data from big databases like ChemSpider and
PubChem. In the future we plan to enable support for spectra and more
sophisticated file formats to have at least some minimum support for
chemistry-related Wiki-works.

I am currently looking for features you would find helpful as well as
your opinion of what is needed to deploy MolHandler to Wikimedia Commons
and therefore created a test wiki[1] at which you can create user
accounts. A non-exhaustive list of features is available for raking by
drag&drop. Or just write here what you at least want, what you would
like to see soon and what is less important to you.

Fwd: One Hundred Million Creative Commons Flickr Images for Research

12 GB of metadata and 50 TB of files released by Yahoo!. «Plus about 49
million of the photos are geotagged!»
http://yahoolabs.tumblr.com/post/89783581601/one-hundred-million-creative-commons-flickr-images-for

Can this dataset help linking projects' articles and Wikidata items to
the images we miss? I can imagine
* a FIST expansion querying the data in some way to find flickr images
"nearby" a geocoded page of ours,
* a bot mapping photo IDs from geolocated Wikidata entries and then a
bot importing on Commons those we lack,
* a Wikidata Game to aid automation in some of the above.
Where an image is in a non-free Creative Commons license, we can
flickrmail the author to relicense it, the success rate is typically
high (we could also do this by bot, if we're able to automatically write
a message mentioning the specific files and the pages where we'd use them).

THIS is the crux of the issue. You are insisting on statue or caselaw to 
prove that these files are Free beyond ALL conceivable doubt because the 
copyright outside Israel is legally ambiguous but in practice any 
copyright that may or may not exist is extremely unlikely to be enforced.

The Wikimedia Foundation lawyers have said that it is OK to host, and the 
majority of people complaining about Commons want Commons to host, files 
that are free beyond reasonable doubt unless and until a _valid_ takedown 
request is received that removes the doubt.

In the Israeli example, the positions can be summed up as:
Israeli government: We don't hold copyright on these images
Commons admins: You haven't explicitly disclaimed copyright outside 
Israel, we demand that you do.
Reasonable people: Only the copyright holder can disclaim copyright, the 
Israeli government say they do not hold copyright and so cannot disclaim 
it.
Commons admins: You're wrong, now go away and get teh Israli government to 
disclaim the copyright they say they don't have.
Reasonable people: But they can't!
Commons admins: We say they can, so they must be able to.
*Repeat*
