RIF testcases API (non-normative)

Proposal:

I suggest for the testcase for BLD based dialects...
to use the SPARQL API (i.e. SPROT, see [1])
with a slight variation of the SPARQL interface:

The standard format for SPARQL queries, a bit abstracted is:

SELECT Vars
FROM dataset
WHERE { graph pattern }
OFFSET integer
LIMIT integer

which we extend as follows:

SELECT Vars
FROM dataset | FROM ruleset
WHERE { graph pattern } | WHERE { rif_condition_w_free_variables_Vars }

rif_condition_w_free_variables_Vars is a RIF condition with
the free variables Vars being a superset of Vars.
and the query should return bindings which if
applied to the condition make the
entailed by the RIF-RDF combination given by the
ruleset and RDF merge of all RDF datasets in FROM clauses.

The good thing is that we can use the input and output format of the 
SPARQL enpoint API as-is in this simple proposal and we should publish 
this as a simple API for RIF testcases at the moment.

The description of this non-normative API should go in the testcases 
document... maybe some more details needed, but I think it is fairly simple.


Axel
