Hello Lora, To view and query existing relational data as RDF triples, use D2RQ: http://www4.wiwiss.fu-berlin.de/bizer/d2rq/ To add more axioms or otherwise change your ontology, either make a copy of the OWL source and edit it, or create a new ontology which owl:imports the existing ontology and adds your new class and property definitions. Jena doesn't require you to "integrate" an ontology, you just read it into an OntModel and start processing. To ask particular Jena support questions, please post to the Jena list: http://tech.groups.yahoo.com/group/jena-dev It generally helps if your questions are as specific and detailed as possible. Do read the tutorial and other documentation first. Hope that helps, Ian ____________________________________________________________ Ian Dickinson http://www.hpl.hp.com/personal/Ian_Dickinson HP Laboratories Bristol mailto:ian.dickinson@hp.com Hewlett-Packard Limited Registered No: 690597 England Registered Office: Cain Road, Bracknell, Berks RG12 1HNReceived on Thursday, 21 February 2008 10:23:09 GMT
