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.

Sorry, am busy and likely in the wrong timezone. I would appreciate
feedback on this though.

You want an example file that has all the fields filled that have been
defined and are possible to be filled? 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.

Silvia.
