Hello, i am working about inferences on Jena. I would test that a property is a particular string. I have an ontology about servers, an individuals like this:
<owl:NamedIndividualrdf:about="&data;serveur-106216"><heberge rdf:resource="&data;applications-105049"/><rdf:type rdf:resource="&data;serveur"/><identifiant-reseau rdf:datatype="&xsd;string">SRVLINMAGZ06</identifiant-reseau><status rdf:datatype="&xsd;string">Enservice</status><svr-numero-serie rdf:datatype="&xsd;string">-</svr-numero-serie></owl:NamedIndividual> i would add a new information (new property) to the servers that have a property identifiant-reseau="POLO" so, for this i have written a Jena rule like this: [rule:(?S rdf:type data:serveur),(?S data:identifiant-reseau "POLO")->(?S data:newproperty "TEST")] But obviously, the test (?S data:identifiant-reseau "POLO") don't work. Please, Have you an idea? Thank you.
