Hi Chris,
thanks for your answer.

This means that LARQ assembler would need to be added to the current RDF Dataset
assemblers. For example, for TDB, see DatasetAssemblerTDB:
https://jena.svn.sourceforge.net/svnroot/jena/TDB/trunk/src/main/java/com/hp/hpl/jena/tdb/assembler/DatasetAssemblerTDB.java

We should check if the root resource has a larq:textIndex property and if LARQ
jar is in the classpath, if so: create the necessary LARQ specific objects and
attach them to the DatasetGraphTDB.

I'll try that.

Thanks,
Paolo
