Dear all, I could see the case for the tag line which could be used for annotation (inc. personal). As concerns the trailer, thumbnail and other related material, we have 'relation' defined as a pair relation-object. Technical metadata could make your list explode ;-) but we should try to think from a player perspective. What can a player do or not do without such metadata and would users base seach on such technical criteria?

We should discuss, whether we need the elements concerning technical metadata. These sound quiet interesting, but i´m not sure if they are in the scope of our "ontology v1.0" right now - and unfortunately they produce some kind of conflicts, as Werner pointed out. I´m looking forward to today´s telecon.
