Cher Frédéric, You just have to use the basic RDF API : http://jena.apache.org/tutorials/rdf_api.html
with the TDB API : http://jena.apache.org/documentation/tdb/java_api.html Note that "update nodes" is not the right wording for what happens. An RDF model is bascally a collection of triples. So adding <a> <p> <o2> . to a model that contains already: <a> <p> <o1> . will not "update" <a> ; there is just one more triples having <a> as subject. 2014-01-29 Frederic Toublanc <frederic.toubl...@telemis.com> > Hello there, > > Here is my question. > > I have an existing TDB containing triples. > I have a RDF file and i want to update the existing TDB with the data > contained in the RDF file. > If nodes already exist they should be updated and new data added. > > Is it possible to do it with the Jena API ? > -- Jean-Marc Vanel Déductions SARL - Consulting, services, training, Rule-based programming, Semantic Web http://deductions-software.com/ +33 (0)6 89 16 29 52 Twitter: @jmvanel , @jmvanel_fr ; chat: irc://irc.freenode.net#eulergui
