I'm also spamming, I suppose ...

The problems with this, the ones that makes me nervous and want to put
this up as a work item for the syntax group are that

1. People like Dan and Eric seem to implement creator roles using
sub-classing of a basic underlying class, creator say. Although much more
elegant, this does not lend itself to putting in schemes and using a
literal as creator role with an rdf:value.

2. The dcq:creatorRole (or is it dcq:creatorEQ? -- please refer to graph
11 [2]) doesn't even appear in the schema definition in appendix 2 [3] in
that document. Not even the infrastructure is there :(

So, while I agree with Stu on the functional requirements, I still think
that this is extremely difficult area which is poorly understood (at
least by me).

PS

By year 2000 we need to be able to say 

Winnie the Pooh was _created_ by AA Milne (rdf:value) who is the _person_
that _authored_ the text
