I think it is a good idea to start from the work done by the incubator 
rather than starting from scratch.
So, I agree with Olaf's idea.

In the case that this is accepted by other members, I would like to draw 
the attention to the following point.
The focus in Section 6 [1] seems to be on how the representation of a 
web resource obtained via HTTP can be enriched with provenance 
information about that resource.
While useful, I was wondering whether other kind of queries, that are 
about provenance, could be supported, or whether they are outside the 
scope of the PAQ TF.
An example query could be, "did resource r1 contribute to the content of 
resource r2?"

Thanks, khalid
