obVerify
January 27th, 2008Motivated by a need to verify creative commons meta-data embedded in mp3’s I wrote a php script to do just that. An explanation of how creative commons meta-data verification can be found here. Basically there is an ID3 tag that you put the location of the license and another verification URL ID3 tag. On the verification webpage there should be some RDF data embedded in the HTML that identifies the licensing terms of the mp3 file. obVerify parses the ID3 tags from the file then checks the verification URL to make sure the information both exists and is consistent.
I plan on using this as part of a site that allows users to upload music. To avoid copyright issues the site will only allow creative commons licensed music and so this script will verify that I can indeed include the uploaded mp3 in my site.
