ok, wasn't entirely clear in which way, i.e. whether these should be in 
the default graph (wouldn't make sense to me), in a named graph (GRAPH, 
also limited sense only), or queryable by an explicit dataset clause 
(FROM). the latter would be the only one that makes sense to me, anyways.

If we rule out Option 5 entirely, we have no defined way of querying the 
service description directly over the very SPARQL endpoint, do we want 
that? I feel somehow this could be useful, but don't really have a 
strong opinion about it either. We could recommend some variant of 
Option 5 on top of one of the others informally and simply not enforce 
everybody to support it?
