Re: [xdi] XDI Querier update

["Markus Sabadello" <markus.sabadello@xdi.org>]

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

=giovanni
    $$
        $$

instead of just

=giovanni

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?

Hello Markus,

thanks for this update. It has been great to see the querier at work yesterday!
Simple question regarding this query:

($$2/+nationality)

is it the same to ask

$$2
  +nationality

instead of

$$2
  +nationality
       $$

?
