It is possible. I can throw an RDF together to list all the fields available. I just don't think it makes much sense for metadata that is encapsulated in a binary file. And this includes other formats such as QuickTime, too. > Please Sylvia could you join the MAWG telecon tomorrow to discuss this > issue. Sorry, am busy and likely in the wrong timezone.

That is easily said for a text file format, but not so easy for a binary format. I'd have to write some code for some of the fields, because not all software uses all fields.
