--------------------------------------
Hi [~andy]
{quote}Is your interest for large data or for large ontology?
{quote}
I'm interested in small ontologies and medium size data. Besides RDFS it's
mostly property chain axioms. I need to be able to change the ontology during
runtime.
{quote}There's no specific support for RL or QL or the OWL2 features.
Contributions welcome!
It can be added as a custom rule to a rule set.
{quote}
I'll try to find out how to create custom rulesets and use them in Fuseki.
{quote}The general inference engine is per-graph. You can set it up to
inference over the union of all named graphs but as inference on each graph
without enumerating the named graphs.
{quote}
Is it possible to inference over the union of all named graphs AND at the same
time query individual named graphs? Something like
{{SELECT ?x ?g WHERE { }}{{{}?x a :Thing . #inferred triple{}}}{{{}graph ?g \{
?x :name "asddf" } # imported triple{}}}{{{}}{}}}
Then I would know from which graph some specific data came from and still get
the inference results from the default graph.

> Project: Apache Jena
> Issue Type: Question
> Components: Fuseki
> Affects Versions: Jena 4.6.0
> Reporter: Stefan Bischof
> 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
