Here the corrected IPTC Eurovision NML-G2 example - the durationUnit attribute was missing and the duration is expressed in seconds, which converts in decimal for the ma-ont instance file.

The zip archive attached contains both the  corrected xml and owl files.

Hi Jean-Pierre,

since the unit of property ma:duration is seconds, the range of this property is xsd:decimal.
However in your example no data type information (xsd:decimal) is provided.

Hi Martin,

Thanks for the feedback. The TVA stuff is of course ultra obvious. Eurovision Newml-G2 file use editUnits as time format -> isn't there an attribute saying that?

Deadline? I am willing to do it when I am terribly busy right now. (I don't know why people are so excited about metadata right -> we did a good job so far to keep it out of reach :) but it seems this time is gone)

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?!
