[Rdfapi-php-interest] Re: dataset->sparqlQuery() Bug?

[Markus S. <m.s...@hi...>]

Hi again,

i fixed the problem in ../rap/api/sparql/SparqlEngine.php in method 
_buildResultSet(). The problem was, that the value of $triple in the 
foreach loop is a Statement object if queried against the default graph 
and otherwise the value is a Quad object if queried against a named 
graph. I hope this fits to your needs and is a real bugfix without 
following a new bug!

regards, markus
