sesame

I've created an application, which works with openrdf sesame and owlim module. Recently, I needed to update licence key to owlim (I received a key for the newest owlim version), so I was forced to update sesame as well. Application was build with sesame 2.6.0 and owlim 4.3, now updated to sesame 2.6.8 and owlim 5.2 There are issues with delete sparql queries, which works in older version, so I got a hunch, that update is the problem. Here is one such query: PREFIX oporg: <http://sesame.company.org/OPropertiesOrg#> WITH <users:> DELETE { ?userID oporg:sessionID ?sessionID } INSERT { ?userID

Add just this one quad to an empty store: <http://x.com/s> <http://x.com/p> 2 <http://x.com/g> . Then execute this SPARQL query (taken from per Bob DuCharme's book 'Learning SPARQL', so this must be standard SPARQL for retrieving all quads across the dataset, regardless of implementation, right!?): SELECT ?g ?s ?p ?o WHERE { { ?s ?p ?o } UNION { GRAPH ?g { ?s ?p ?o } } } But Jena and Sesame reply with different answers!!? Here's what I see: Jena Fuseki console on Tomcat 6.0.37 (version 2.10.0 - out-of-the-box, no configuration changes!) - (the correct answer as I understand things): ----------

I'd like to copy all the data from an existing Sesame repository into a new one. I need the migration so that I use OWL-inferencing on my triplestore which is not possible using OWLIM in an In Memory repository (the type of my existing repository). What is the most efficient way to copy all triples from a repository into a new one? UPDATE 1: I'm curious to understand why using SPARQL INSERT cannot be a valid approach. I tried this code under the SPARQL Update section of a new repository: PREFIX : <http://dbpedia.org/resource/> INSERT{?s ?p ?o} WHERE { SERVICE <http://my.ip.ad.here:8080/openrdf

My team is implementing a variation of Ceusters's Referent Tracking . In our implementation, the original URI for an entity can be changed (to something containing a UUID), although a link to the original URI is always kept. For example: :Joey rdf:type :person . :New_York_City rdf:type :locality . :Joey :hometown :New_York_City . might become: :Joey :replacedWith :ABC123 . :ABC123 rdf:type :person . :New_York_City :replacedWith :FFF555 . :FFF555 rdf:type :locality . :ABC123 :hometown :FFF555 . I am writing some Scala integration tests to see if our software does the referent tracking correctly

I have an RDF file and I need to extract some information from it and write it to a file. I understood how it basically works, but I'm stuck with this: String queryString = "select ?person ?children where { ?person ?hasChildren ?children}"; TupleQuery tupleQuery = conn.prepareTupleQuery(QueryLanguage.SPARQL, queryString); TupleQueryResult result = tupleQuery.evaluate(); while (result.hasNext()) { BindingSet bindingSet = result.next(); Value p1 = bindingSet.getValue("person"); Value p2 = bindingSet.getValue("child"); println(p1 + " has children " + p2 +""); } result.close(); The output I get is

I'm using booth Sesame .wars in Tomcat 7 on OS X 10.8, but now it doesn't work any more. I set up a new Tomcat with two new Sesame .war but now it uses the old repository. Where are these stored? (Couldn't add a new Repo or delete the old one). Sesame Server by default stores its configuration data and database files in %APPDATA%\Aduna on Windows, $HOME/.aduna on Linux, and $HOME/Library/Application Support/Aduna on Mac OS X. If you want a completely new install, simply delete this directory. See the Sesame manual for more info. Update you can check where your Sesame server installation stores
