Paolo Castagna commented on JENA-164:
-------------------------------------
> And I've suggested LARQ could create a DatasetGraph and catch every
> add(quad)/delete(quad).
>
> A LARQ assember could simply name the dataset description it wraps.
> Assemble the LARQ assember assembles the inner dataset. Fuseki service
> points to LARQ.
>
> Seems quite practical to try to me.

> LARQ used not to update the Lucene index as RDF statements were added/removed
> from a Jena Model.
> LARQ is currently extending StatementListener [1] to keep a Lucene index in
> sync with a Jena Model, however this notification mechanism is not applicable
> in the case of SPARQL Update requests.
> LARQ needs to update the Lucene index when a SPARQL Update request is
> received.
