Subject: Re: [xdi] XDI Querier update
apart from the implementation, maybe in the specification we should allow both forms. One question may arise about the usefulness of $$ if we allow the first form; well the answer may be a thing like this:
of course we could anyway use $$1 instead of $$ here, but I would prefer to have an explicit different form for the unbounded variable ($$) than the one used for the bounding ones ($$1, $$2, etc.) - I think this could be useful to optimize performances in implementations - what do you think?

Hmm no, right now the query engine only selects input statements that fully match a query statement. So if a query statement contains only a subject and a predicate, then it will only select input statements with only subject and predicate, not input statements with subject, predicate and something else.
So even if you just want to know everything about =giovanni, you would have to enter
instead of just
The latter will only work in my implementation of XDI messaging, but not in the XDI query engine.
But maybe it should work that way too?
