Hi everyone,

At first, I'm completely new to the jena and the topic of triplestores at all.
I would like to  separate  my ontology (schema) and my instances/entities
  in Fuseki. So I have to load my owl/rdf file and mix it with the entities
  somehow.
This seem to be quite similar to that topic:

http://mail-archives.apache.org/mod_mbox/jena-users/201205.mbox/%3c938cdbec-6735-4e35-a3d6-5e88a4539...@rpi.edu%3E

<#rdfs_model> rdf:type ja:UnionModel ;
     ja:subModel <#document_dataset> ; <--- this I should substitute with my 
schema file?
     ja:rootModel <#tdb_dataset> ;

These have to be models (graphs), not datasets (collections of graphs).

Instead of <#document_dataset> could I use something like that:?

<#document_dataset>    rdf:type ja:RDFDataset ;  <-- Is RDFDataset useable for 
OWL in RDF-Syntax?
    rdfs:label "schema" ;
     ja:defaultGraph
       [ rdfs:label "schema.rdf" ;
         a ja:MemoryModel ;
         ja:content [ja:externalContent <file:Data/schema.rdf> ] ;
       ] ;
     .

If you want TDB-backed graphs:

<#graph> rdf:type tdb:GraphTDB ;  <--- use <#graph> above
    tdb:dataset <#dataset> .

<#dataset> rdf:type tdb:DatasetTDB ;
    tdb:location "DB" ;

Could someone be so kind as to give me a hint for that?

Thanks
Tom
