Hugh,

I agree with Juan that these are questions for step 9:-)

However, one data point: as far as I can see and understand, the Property Graph model does not put the kind of emphasis RDF does on the usage of URI-s for the nodes and links. You can, of course, use a URI for the identification of nodes, but I would expect that the practice is to add a URL as 'label' to a node or a link.

The discussions on PG<->RDF at the workshop concentrated on ways to add such labels to RDF predicates, but you are right that the role of URL-s must be looked at as well…

Cheers

Ivan
