How can I configure Fuseki so works in-memory with a reasoner on?
I have a ontology with ~5000 triplets and a few rules, with Fuselo 3.10.
But it’s really slow when doing something like this:
SELECT DISTINCT ?class ?prop ?nombre ?p ?cat
WHERE {
?class a owl:NamedIndividual .
?class su:tienePropiedad ?prop .
?prop su:categoria ?nombre .
?nombre ?p ?cat .
FILTER NOT EXISTS {
?nombre a ?other .
?other rdfs:subClassOf ?cat .
FILTER(?other != ?cat)
}
FILTER(isUri(?class) && STRSTARTS(STR(?class), STR(su:)))
}
LIMIT 25
I've been searching in the mailing list and I found that it's something
common: Slow query when getting rdf:type
<https://markmail.org/message/qnsfm3ynorxmlupx>
I found some examples of how to modified the config file. This is my
ssrsi.ttl (server config)
@prefix : <http://base/#> .
@prefix tdb: <http://jena.hpl.hp.com/2008/tdb#> .
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> .

] ;
But doesn't work the reasoner (I've been using this tutorial for making

)
So how do I configure the server to work as in-memory with the reasoner?

This will need to be a ja:RDFDataset.
An example:
