> Status of OWL 2 support
> -----------------------
>
> Key: JENA-2346
> URL: https://issues.apache.org/jira/browse/JENA-2346
> Project: Apache Jena
> Issue Type: Question
> Components: Fuseki
> Affects Versions: Jena 4.6.0
> Reporter: Stefan Bischof
> Assignee: Andy Seaborne
> Priority: Major
>
> What is the status of OWL 2 (OWL 2 RL or OWL 2 QL) inference support in Jena?
> Particularly, is there a way to configure Fuseki to support property chain axioms?
> Additional question: Is there a way to configure Fuseki with inference AND named graphs? The configuration I came up with, only contains the default graph:
> {code:java}
> <#service> rdf:type fuseki:Service ;
> fuseki:name "ds" ; # http://host:port/ds
> fuseki:serviceQuery "sparql" ; # SPARQL query service
> fuseki:serviceUpdate "update" ; # SPARQL update service
> fuseki:serviceReadWriteGraphStore "data" ; # SPARQL Graph store protocol
> fuseki:dataset <#dataset> ;
> .
> <#dataset> rdf:type ja:RDFDataset;
> ja:defaultGraph <#inferenceModel>
> .
> <#inferenceModel> rdf:type ja:InfModel;
> ja:reasoner [ ja:reasonerURL <http://jena.hpl.hp.com/2003/OWLFBRuleReasoner> ];
> ja:baseModel <#baseModel>;
> .
> tdb:GraphTDB rdfs:subClassOf ja:Model .
> <#baseModel> rdf:type tdb:GraphTDB; # for example.
> tdb:location "/fuseki-base/databases/tdb";
> # etc
> .
> {code}
