Thanks for your answer. So that's a feature. The reason why I encountered this problem is that I wanted to remove a part of my model. So this query was supposed to return the statements to remove from my model. I have to do it another way. For information, since I have no experience yet of performing such an operation, what is your favorite way of removing part of your model when it contains blank nodes ? I mean, the less painful one, of cource :-) Regards, Maxence _______________________________________________ redland-dev mailing list [email protected] http://lists.librdf.org/mailman/listinfo/redland-dev
