I looked - there are a couple of problem bocking its use which need fixing:

Andreas,I'll take a look - one of the problems of running that service has been (unsurprisingly) it getting trashed. A public endpoint reading files from the web is a DOS vector. People trying to load DBpedia etc. (no, that does not work!).(The VM it runs on is also quite locked down which may be the issue as well).If you are using the apache-jena-fuseki dwn and service scripts, that is the webapp server. The standalone form is Jetty+Fuseki as webapp.It will be better to run the general query endpoint in a separate server - that isolates it from the handling of the datasets.Andy On 13/02/2019 10:51, Walker, Andreas wrote: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 <a...@apache.org> 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?

The only thing I have come up with so far - as an idea, not tested - isloading the RDF file into a named graph, querying it and then dropping itagain. What I am asking is whether there is a simpler way of instructingFuseki to temporarily load that graph just for the purposes of one query.Best, Andreas ________________________________ Von: ajs6f <aj...@apache.org> Gesendet: Dienstag, 12.
