Hi,
I am currently finishing the work of someone else which also includes a
QueryEngine and a Rewrite of queries (basicly adding a FILTER-statement). The
adding-part works fine and does exactly as expected. When I rewrite the query
SELECT ?x ?y ?z WHERE {?x ?y ?z} I get SELECT ?x ?y ?z WHERE {?x ?y ?z . FILTER
restOfFilter}
However, when I take this query and send the same request for rewriting I get
an alteration of the FILTER that is in the original Query send. Here is the
beginning of the original Filter (first one) and the correct FILTER, that has
been added :
FILTER ( ( ( isLiteral(?x) || ( ( ( ! isBlank(?x) ) && isIRI(?x) )
FILTER ( ( ( isLiteral(?x) || ( ( ! isBlank(?x) ) && ( isIRI(?x)
But it should really be the same FILTER statement twice. If tracked down the
problem to the line:
_query = QueryFactory.parse(_query, _queryQurrent, null, null);
This is, where the alteration occurs. Another weird thing is, that it does not
occur with other queries, that went through the same process.
I have no clue, why this happens, so I hope someone can help me with this.
Thanks in advance.
Sincerely
Christian Pechhold
