* License metadata validation web application.
* License claim embedding specifications for more file types.
* APIs for Creative Commons license metadata.
* GUI for embedding license claims in files and generating claim verification RDF.
* Build Creative Commons licensing into more content creation applications.
* Browser toolbar or plugin that extracts and displays license metadata embedded in a page.
* Media player and file sharing applications that read, verify, and display license claims embedded in files.
* Add license search to a major commercial search engine.
