I am very interested in the way used for to do this. Other colleagues and I, we are studying some approaches developed for incremental update of RDF graphs in linked data context, more specifically, RDF graphs updated from a legacy relational database.

We do not use incremental updates currently.

The application changes the data in the triple store by doing DROP/INSERT on
single named graphs. The SPARQL endpoint with triples is completely regenerated
once per day with a federated query to the named graph SPARQL endpoint:
"DROP ALL\nINSERT { ?s ?p ?o } WHERE { SERVICE <..". We can probably go a long
way before this gets impractical.
