Re: [Virtuoso-users] Conversion to RDF issue.

2017-02-27 Thread Lorenz B.
Protege is designed for OWL ontologies, not for plain RDF. If your RDF dataset does not declare the type of the properties w.r.t. OWL syntax, i.e. either owl:ObjectProperty or owl:DatatypeProperty, they're considered annotation properties. > Hello! > Today I tried to export an rdf file that was cr

Dear Virtuoso team, I've got a small question which came up during the discussion here [1]. Which kind of REGEX engine/flavor does Virtuoso (7.x) implement? I couldn't find anything in the documentation but probably I overlooked the relevant part :D [1] http://stackoverflow.com/questions/4043760

Hello Jerven, good catch. Now, I'm wondering whether BIND has to be evaluated after the FILTER or if this isn't specified in the SPARQL standard. Or does the order in the SPARQL query matters in that case like it does for OPTIONAL clauses? Kind regards, Lorenz > Hi All, > > I think it is an is

Hello Jindřich, to my understanding, the assumption is that any SPARQL update will be executed completely, otherwise it fails with some error messages or the like. Cheers, Lorenz > Hi Hugh, > > thanks, that supports my assumption. Are you aware of any other > mechanism to tell if a SPARQL upda

Hello Maria, I'm not a Virtuoso developer, so I can't help you and the query is rather simple. Probably depends on your settings and the size of the dataset. It's also not clear what "long" means in your case. Off-topic, but: please don't use predefined namespaces like RDF, RDFS or OWL for your
