fuseki

I want to use pellet reasoner with my Fuseki 2.3.1 First: I added Pellet reasoner to my config.ttl as this: ja:reasoner [ ja:reasonerClass "org.mindswap.pellet.jena.PelletReasonerFactory";] So now I have to add the jar for Pellet to fuseki This page explains how to add jars (not specificaly pellete) to fuseki https://jena.apache.org/documentation/permissions/example.html So I commet this line exec $JAVA $JVM_ARGS -jar "$JAR" "$@" and I uncommet this line java $JVM_ARGS -cp "$JAR:$APPJAR" org.apache.jena.fuseki.cmd.FusekiCmd "$@" and uncomment the line that starts with APPJAR= now I still need

I want to download two or more datasets on my machine and be able to start a SPARQL endpoint for each. I tried Fuseki which is part of the Jena project. However, it loads the whole dataset in memory, which is not very much desired if I'm intending to query large datasets like DBpedia given that I intend to do other stuff (starting multiple SPARQL endpoints and use a federated query system over them). Just to give you a heads up, I intend to link multiple datasets using SILK , querying them using a FEDX federated query system. If you recommend any change of the systems I'm using, or can give me

I mostly use SPARQL SELECT while working on a query for debugging purposes but in the end I want to use the final result it in a CONSTRUCT way; as I want to work with a graph and not key/value query results. What I don't get yet (and can't seem to find with search engines/docs) is if I can use functions as well that way. As an example, I use a property path to concatenate titles I get into a "superstring", which I later use for building a Lucene index to increase plain text search quality: PREFIX dc: <http://purl.org/dc/elements/1.1/> SELECT (group_concat(?title ; separator = " ") AS
