I want to configure Fuseki with an inference model supported by TDB.
I have been able to configure it with a Memory Model, but not with a TDB Model
where I could update triples.
I am using the following assembler description:
@prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .
@prefix rdfs: <http://www.w3.org/2000/01/rdf-schema#> .
@prefix ja: <http://jena.hpl.hp.com/2005/11/Assembler#> .
@prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> . [] ja:loadClass
"com.hp.hpl.jena.tdb.TDB" .
tdb:DatasetTDB rdfs:subClassOf ja:RDFDataset .
tdb:GraphTDB rdfs:subClassOf ja:Model . <#dataset> rdf:type ja:RDFDataset ;
ja:defaultGraph <#infModel> . <#infModel> a ja:InfModel ; ja:baseModel
<#tdbGraph>; ja:reasoner [ja:reasonerURL
<http://jena.hpl.hp.com/2003/RDFSExptRuleReasoner>]. <#tdbGraph> rdf:type
tdb:GraphTDB ; tdb:location "DB" ;
.
It works fine and it is able to do RDFS inference and even to insert new
triples. However, once I stop and restart the server, it raises the following
exception:
Error 500: Invalid id node for subject (null node): ([000000000000001D],
[00000000000000AF], [000000000000003D])
After that, I can do a "CLEAR ALL" and insert triples again...however, once I
restart the server, I obtain the same exception...
Best regards, Jose Labra
