I'm getting a lot of errors querying against:
http://www4.wiwiss.fu-berlin.de/factbook/sparql
while some queries work, e.g.
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT ?s WHERE {
?s rdfs:label ?label .
FILTER REGEX(?label, "libya", "i")
}
many others fail, e.g.
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
SELECT DISTINCT * WHERE {
<http://www4.wiwiss.fu-berlin.de/factbook/resource/Libya> ?p ?o
}
