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."

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?
