Dear Jean-Pierre,
While looking at the MA ontology examples, I recognized some issues in the examples you provided:
In the iptc example [1], there is no data type information attached for duration (<ma-ont:duration>209</ma-ont:duration>).
In the tva example [2], the property hasRelatedMediaResource is used which is not part of the MA ontology spec. Instead hasRelatedResource can be used.
Can you please address these issues?!
