PROV-ISSUE-145 (Tlebo): qualified identifiers may not work well with named graphs [Data Model]

http://www.w3.org/2011/prov/track/issues/145

Raised by: Timothy Lebo
On product: Data Model

There is a note in prov-dm:

"We are going to introduce a notion of qualified identifier, which allows us to refer to an identifier in the scope of a given account. Given that accounts may be nested, a qualifier identifier will be prefixed by a sequence of account identifiers, and then followed by an identifier, local to the innermost account."

This non-global scoping mechanism will prevent the many nice uses of out-of-the-box named graphs, and instead require an entire extra level of implementation that is not currently supported in triple stores.

I propose that we require the asserters to define appropriately-scoped URIs for their identifiers. Letting them be lazy up front will cause headaches when actually trying to use it.
