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.
