Hi Andy,
n is illegal SPARQL, ok, but that does not means that can be used to
refer a outer variable? The symbol “” can appear
with sparql commands. To finish, I only need to define the
special char to make reference to outer variables (for now, and to develop the
engine, I'm using a non-valid char).

Hi all,
In a Sparql query, we can extract the query pattern ( q.getQueryPattern() ).
For instance, in the sparql command:
Select ?x ?p ?z where {?x ?p ?y . ?x eg:p ?z.}
we can extract:
{ ?x ?p ?y .
?x eg:p ?z
}
Is there anyway to extract as TriplePattern?
Hi All,
I couldn't implement the hook between a Sparql command and rules terms. In my
opinion, only make sense hook a Sparql command and rules terms if in the sparql
command we can invoke variables from rules terms. Something like:
(?x eg:p ?y),
(\\\sparql Select ?z where {y
. It is
possible but, as also mentioned, it might be better to start over with a
fresh engine in that case.
