OK, so this begs the question -

Is it already agreed upon that the TagCommons WG output is to be 
expressed as RDF?

I have no background in the use of RDF Schemas for such purposes, 
although I can read and understand, to some extent, the kind of subject 
matter discussed under the Annotea effort. But, and this needs to be 
said, if we want to interoperate with existing web apps in ways that 
draw in members of these
communties, then we have to be able to express the subject matter in 
multiple formalisms.

I looked at the Annotea web site and find the extended notion of an 
Annotation rather than just a tag, appealing and powerful.
But for people not in the Semantic Web area to use it, and many such 
people would want to use these ideas, we have to be able to express them 
in other ways than RDF.
If I have to swallow the RDF infrastructure kool-aid then I am less 
likely to get excited about it.

So I will put on my asbestos suit as I ask :-

Is there a way to express the Annotea relationships in ER diagrams?  Has 
this been done?
Are there fundamental reasons aside from performance why this is not a 
good idea?

Nitin.
