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

[<tob...@we...>]

Hi Markus,
thank you for your bug report. The problem is in method 
findInNamedGraphs($graphnode,$subject,$predicate,$object) of DatasetMem 
and DatasetDb. The method of DatasetMem returns an iterator over all 
matched triples OR quads depending on the value of $graphnode. The 
method of DatasetDb returns always an iterator over all matched quads.
I fixed it and put it in our CVS.

Regards,
Tobias
