Re: Strawman DAML+OIL Query Language Proposal

From: Mike Dean (mdean@bbn.com)

One use of a query language could be to return a subgraph,
e.g. all of the AirportCode instances at [1] along with
their latitude and longitude properties where country =
"USA".  With the current proposal, the client would have to
reconstruct the subgraph based on the variable bindings.  We
might want to have some option to also return the matching
statements directly as DAML content.

Also, I assume the conjunctive nature of the proposal means
the client couldn't ask for country = "USA" or country =
"Canada" in a single query.
