How do other people use Wikidata dumps if they are not using the "official" (with sparql or so) way of querying it? I have done some pretty raw extraction from it (e.g. download the already pretty large zipped json dump, then unzip it on the fly and parse the json, and extract triples and entities). Not sure if that is really quite efficient, but the dumps are hard to work with, and I really just needed the entities in one language and the triples/graph of them.
