Hi Veronique,

I think this use case is very interesting.

Felix is right when he says that the information management issue, i.e.
the recording of the metadata which might occur in the processes, has to
be mainly solved in that area.

But I also agree to Veronique, that a great problem is, that different
tools which are used in the media production lifecycle use different
metadata formats. Which means as soon as a media item is imported into
an application, the metadata might be lost. And I also see a
contribution from our media ontology there, i.e. to provide the means to
transform between the formats. We experienced this problem in one of the
projects I worked in.
