But getting such an ontology developed may be a research effort... If I recall correctly you mentioned that kinds of efforts as "(a) relate all media annotation systems by means of a firm semantic background, so that a machine translator can do the best it can ('the tag called title is the formal_name of the work', 'the tag called author is the formal_name of the person who created the words of the work')" and also mentioned your preference for "(b) have a small set of tags which we encourage should be implemented in any standard." in http://lists.w3.org/Archives/Public/public-media-annotation/2008Sep/0045.html Hence I am wondering: Do you think that the mapping table is a useful contribution to b), or rather to a)? What value and purpose do you see in the mapping table in general? Felix
