Quite; we have not.

We have a pending objective including...

"It must be possible for the query language and protocol to allow an RDF
repository to expose the source from which a query server collected a
triple or subgraph."
http://www.w3.org/2001/sw/DataAccess/UseCases#d4.2

and an issue

http://www.w3.org/2001/sw/DataAccess/rq23/#i_sourceImplExp

I notice the design doc says "Is this still a requirement?"

  $Revision: 1.39 $ of $Date: 2004/08/24 13:35:32 $

as if it were a requirement at some point. I don't believe it
ever was. Please drop the "Is this still a requirement?"
bullet.

The lack of a requirement only means that the design
is *unconstrained* in this respect.

WG members are free to propose all sorts of designs, including
those that omit SOURCE altogether... though to do that would
be to take a position on the pending objective too.

As of our last telcon discussion[24Aug]
DaveB is still the issue owner, so he owes us another
proposal. That's not an exclusive lock or anything, though
everybody's always welcome to propose ways to address open
issues -- especially the editors.

Hmm... that reminds me... I've got an action on this
issue too...

 EricP, where are the minutes?
