Hi Andy,
I am running Fuseki as a service (i.e. with "fuseki start"), without any modifications to the configuration. I have added a dataset with multiple named graphs through the web interface, and I tried running the queries through the web interface as well, although I am later planning to query the SPARQL endpoint via Python. When I try the following minimal query in <http://www.sparql.org/sparql.html>, it also doesn't work: SELECT ?s ?p ?o FROM <http://id.loc.gov/vocabulary/iso639-2/deu.rdf> WHERE { ?s ?p ?o } Do I understand you correctly that this should work? If yes, any idea what I might be doing wrong? And how would I tell my own server to allow queries like that? Thanks for your help, Andreas ________________________________ Von: Andy Seaborne <[email protected]> Gesendet: Mittwoch, 13.

If the service is backed by a dataset it will use the graphs from the dataset but there is the "general" query service as well. It is --general in Fuseki.main and that is what http://www.sparql.org/sparql.html is using. Andreas - were you looking for it in the webapp version?
