Hi, I am trying to get alternative names of given names in WikiData with the following simple query: PREFIX ps: <http://www.wikidata.org/prop/direct/> PREFIX wd: <http://www.wikidata.org/entity/> PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#> CONSTRUCT {?s rdfs:label ?o} WHERE { ?s ps:P31 wd:Q202444. ?s rdfs:label ?o} LIMIT 1000 Initially, the query was much more complex, but I was getting time-outs on the public WikiData SPARQL endpoint. I decided to use Linked Data Fragments to offload some filtering from the server to the client. comunica-sparql "https://query.wikidata.org/bigdata/ldf" -f query > given_names.n3 (where "query" is a file with the SPARQL query shown above). Unfortunately, the client tries to get output from the 3rd page, I am getting the following error: Could not retrieve https://query.wikidata.org/bigdata/ldf?subject=http%3A%2F%2Fwww.wikidata.or… (500: unknown error) Following the link in fact returns HTTP 500 error with Error details java.lang.IllegalStateException The link points to the 3rd page. It works if you try to go the second page: https://query.wikidata.org/bigdata/ldf?subject=http%3A%2F%2Fwww.wikidata.or… Is this a bug or a limitation of a service? With kind regards, Maciej Gawinecki
