Squebi hides too much the error in the query evaluation, right. But if it's a public instance, you can see the error response either accessing the http console of your browser or sending directly the query to the endpoint:
curl 'http://marmotta.tno.nl:8080/marmotta/sparql/select' -H 'Content-Type: application/sparql-query;charset=UTF-8' -H 'Accept: application/sparql-results+json' --data-binary $'PREFIX rdf: < http://www.w3.org/1999/02/22-rdf-syntax-ns#>\nPREFIX xsd: < http://www/w3/org/2001/XMLSchema#>\nPREFIX odysseus: < http://marmotta.tno.nl:8080/marmotta/context/>\nPREFIX cmo: < http://www.modelservers.org/public/ontologies/cmo/cmo.ttl#>\nPREFIX depc: < http://www.modelservers.org/public/ontologies/odysseus/depc.ttl#>\nPREFIX rome: <http://www.modelservers.org/public/ontologies/odysseus/rome.ttl#>\n \nSELECT ?Profile ?TimeStamp ?Quantity\nWHERE\n{\n GRAPH odysseus:romedata\n{\n {\n ?Profile depc:measuredBy rome:1824 ;\n depc:hasTimePointProperty ?TimePoint .\n ?TimePoint depc:timeStamp ?TimeStamp .\n ?TimePoint cmo:quantity ?Quantity . \n FILTER (xsd:dateTime(?TimeStamp) > xsd:dateTime(\'2015-09-01T00:00:00\')) .\n FILTER (xsd:dateTime(?TimeStamp) < xsd:dateTime(\'2015-09-01T02:00:00\')) .\n}\n}\n}' And see the stacktrace: org.apache.marmotta.platform.core.exception.MarmottaException: error while evaluating query at org.apache.marmotta.platform.sparql.services.sparql.SparqlServiceImpl$5.call(SparqlServiceImpl.java:311) at org.apache.marmotta.platform.sparql.services.sparql.SparqlServiceImpl$5.call(SparqlServiceImpl.java:279) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) Caused by: org.openrdf.query.QueryEvaluationException: Unknown function ' http://www/w3/org/2001/XMLSchema#dateTime' at org.openrdf.query.algebra.evaluation.impl.EvaluationStrategyImpl.evaluate(EvaluationStrategyImpl.java:1529) ... Which basically says that xsd:dateTime() is not a valid function. So it looks there is an issue with the cast functions. Please, report the details to Jira and we'll see how to address it. Apologize for that problem. Cheers, On Wed, Sep 23, 2015 at 2:07 PM, Bohms, H.M.
