Hi Marco,
The cookie header warnings are just warnings.
The query as written has the LIMIT is outside the SERVICE clause. This means it
fetches *all* labels from the remote endpoint, and then discards all but the
first ten on the client. On my machine, TBC actually runs out of memory before
the query can complete.
The query works for me if I rewrite it to do the LIMIT on the remote server:
SELECT ?label WHERE {
SERVICE <http://query.wikidata.org/sparql> {
SELECT ?label {
?uri rdfs:label ?label
}
LIMIT 10
}
}
Hope that helps,
Richard
