Hi Christopher,
The query reported as failing in the DBpdia bug report:
SELECT ?label WHERE {
?it <http://www.w3.org/2000/01/rdf-schema#label> ?label
FILTER regex(str(?label), "^align", "i")
}
LIMIT 1
Works for me against the DBpedia SPARQL endpoint:
http://dbpedia.org/sparql
Although I did have to increase the query timeout on the page as initially is
was timing out:
http://dbpedia.org/sparql?default-graph-uri=http%3A%2F%2Fdbpedia.org&should-sponge=&query=SELECT+%3Flabel+WHERE+{%0D%0A%3Fit+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23label%3E+%3Flabel%0D%0AFILTER+regex%28str%28%3Flabel%29%2C+%22^align%22%2C+%22i%22%29%0D%0A}%0D%0ALIMIT+1&format=text%2Fhtml&debug=on&timeout=50000
How is the reporter of the DBpedia bug report running the query, is it also
directly against the SPARQL endpoint or via some other means ?
Best Regards
Hugh Williams
