Hi: I'm trying to use librdf to execute SPARQL queries over Virtuoso. But, after getting errors trying to use some functions such as fn:substring (having the fn prefix declared inside the query) I've decided to take a look at Virtuoso's log (after enabling Virtuoso log features using trace_on())
To my surprise, although I successfully retrieve results, some of the queries I perform are not logged at all, and other queries are similar to the ones I intend to pose but are not the same. Moreover, I've tested my queries using Virtuoso Conductor web client and they run as expected. So, my questions are the following: is librdf doing some parsing or re-writing on my queries? Is it somehow "loading" the model from Virtuoso and using its own querying capabilities to execute my queries? If so, how can I skip this step in order to force Virtuoso to process the queries? thanks in advance Lorena -- Lorena Etcheverry _______________________________________________ redland-dev mailing list [email protected] http://lists.librdf.org/mailman/listinfo/redland-dev
