Hi!
I'm curious about how the SPARQL endpoint is quite up to date with live editing. So far I've found only the RDF dump generator via Wikidata Toolkit [1] and seems to me a too heavy process for this.
There are others way to extract triples from wikibase? New edits on Wikidata are loaded on its SPARQL endpoint via SPARUL?
We have a custom software (see https://github.com/wikimedia/wikidata-query-rdf/) that uses Wikidata recent changes API and Wikidata export (e.g. https://www.wikidata.org/wiki/Special:EntityData/Q42.ttl?flavor=dump) to syncronize the data between Wikidata and SPARQL database/
