Hi! Thanks for this big open project. I need help with the next problem:
I use https://librdf.org/query for test my Wikidata queries, but I have problems related to the URI, the Wikidata endpoint is https://query.wikidata.org/sparql, and the query is: SELECT (COUNT(?var3) as ?count) WHERE { ?var3 <http://www.wikidata.org/prop/direct/P31> ?tmp1 . ?tmp1 <http://www.wikidata.org/prop/direct/P279> ?var1 . ?var3 <http://www.wikidata.org/prop/direct/P31> ?tmp2 . ?tmp2 <http://www.wikidata.org/prop/direct/P279> < http://www.wikidata.org/entity/Q879050> . } And it results: Results *SPARQL warnings:* 0:Ignored non-ftp/http URI https://query.wikidata.org/sparql 1:Variable var1 was bound but is unused in the query 1:Variable var1 was bound but is unused in the query 1:Variable $$agg$$0 was used but is not bound in the query Variable bindings result format Found 0 results If I test with Wikidata endpoint with http (this is redirected by default to https), it results: Results *Loading URI http://query.wikidata.org/sparql <http://query.wikidata.org/sparql> failed with errors:* Resolving URI failed with HTTP status 403 My question is: could you please tell me if the problem is http/https (I'm new in this)? is it exist a way to make the query without problems for Wikidata using Redland or Rasqal? Thanks for help! Hugo Sepúlveda
