Hi Sylvia

Providing an RDF file was decided back at the MAWG F2F in Lyon.
And it is mentioned in our exit Criteria for CR.

Therefore if providing an RDF file is not possible for OGG we should 
etheir change our exit criterie, else formats not providing an RDF would 
be removed from the spec.

Please Sylvia could you join the MAWG telecon tomorrow to discuss this 
issue.
Joakim could you add it to the agenda ?

Now about your OGG example, you should provide *all* the properties 
mapping to the properties core set (see ogg mapping table)




like :
identifier, title, language, locator, contributor, location, description 
, etc.

Best,

thierry
