We currently publish license claim embedding recommendations for [[MP3]] and [[OGG]] files. We want to publish similar recommendations for every popular "media" file format including Quicktime, Windows Media, PDF, GIF, JPEG, PNG, Flash... Can you research a file format and suggest a specification? We also need people to provide implementations of our recommendations in various languages, e.g., a Java library that embeds, reads, and verifies license claims. See the [http://cctools.sourceforge.net/ cctools] project for existing implementations.<br />

<br />
* Creative Commons' [http://cctools.sourceforge.net/ cctools] has some reference implementations<br />
** [[Command Line Tools|CC Command Line Tools]]<br />
** [[CcPublisher]] is a tool for generating license information for a file and optionally uploading it to the [http://www.archive.org Internet Archive] for free hosting (forever)<br />
<br />
== TODO ==<br />
<br />
* (DONE) Make specs/implementations a top-level category, with each format it's own challenge.<br />
* Upon completion of a spec, issue a challenge for implementations in different languages and addition of support to existing libraries.</div>Chrismollis
