Embedding Specifications

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 cctools project for existing implementations.

  • CC Command Line Tools

TODO

• (DONE) Make specs/implementations a top-level category, with each format it's own challenge.
• Upon completion of a spec, issue a challenge for implementations in different languages and addition of support to existing libraries.
