Hello everyone,
I'm writing on behalf of a Wikidata Research Project
<https://meta.wikimedia.org/wiki/Research:Understanding_Wikidata_Queries>
into
SPARQL-Queries.
I was wondering if anybody could help me understand why (and how) this
query:
SELECT DISTINCT ?item
WHERE
{ ?tree0 wdt:P31 ?item . BIND (wd:Q146 AS ?tree0) }
is being accepted by
query.wikidata.org.
The reason I'm asking is that we are trying to parse the queries from
the wikidata logs and analyze them for different features. At the moment
we are parsing them using OpenRDF, which fails (as far as I can see
understandably) at parsing this query.
Greetings,
Adrian
