We have loaded Wikidata into a Virtuoso instance
accessible via SPARQL [1]. One benefit is helping to understand Wikidata using our Faceted
Browsing Interface for Entity Relationship Types [2][3].
That's great news, thanks!
Feedback always welcome too :)
So, I've eagerly tried a very simple SPARQL query with a huge result
set, the complete version of which¹ I've known for several years to
timeout in both the official Blazegraph instance and a personal
Blazegraph instance with supposedly all time limits removed:
PREFIX wd: <http://www.wikidata.org/entity/>
PREFIX wdt: <http://www.wikidata.org/prop/direct/>
SELECT ?person WHERE {
?person wdt:P31 wd:Q5
}
… and while the Virtuoso instance manages to answer pretty quickly, it
seems that it's cutting the result set at 100k triples. Is it the
expected behavior? If so, I suggest you show that in the UI because
apart from the improbable round number of triples, it's not obvious
that the result set is incomplete (in this case, the LDF endpoint
tells us that there should be around 5,4M triples²).
Thanks again!
