On October 6 we posted a list of technology challenges that we hoped would inspire developers.

It did inspire one: Nathan Yergler has already created and made a few rounds of improvements to a web app that validates and extracts license metadata, just as called for.

As an example of what Nathan’s application can do, see what it says about the metadata in the web page about our new Copy Me/Remix Me compact disc. Hint — the metadata serves to verify license claims embedded in MP3s of the songs on the disc, per our MP3 license embedding strategy.
