Greetings, I just joined the list but have been working with jena and other semantic web tools and apps for awhile. I've been trying to get fuseki running and think I'm really close to what I want to do with it, but not quite here.
I'm working with a semantic web application called Vivo (vivoweb.org) which uses a SDB backed with MySQL. I've written a java web app which manages sparql queries, issues them against a joseki SPARQL endpoint and returns the results in multiple formats (basically similar to what elda is doing.) That's been running in production for over a year but because we've run into issues with joseki hanging up (we've got a restart script the runs periodically to restart the service) and elda is quite a bit more robust then the webapp I wrote I'm looking at a elda/fuseki/vivo configuration that will be used for a project that I am working on for a well known UN organization. I've got an elda/joseki/vivo implementation working and it serves up LOD datasets fine so far but I'm running into issues replacing joseki with fuseki. I built a fuseki instance from the 0.2.1-SNAPSHOT and added SDB support and MySQL libraries. It starts up without any errors, but when I access it from elda (or the s-query tool in the fuseki dist), fuseki is handling the query but returning no results. My test, using s-tools, looks like this: ./s-query --service http://localhost:3030/ds/sparql 'SELECT * {?s ?p ?o}' Which returns: { "head": { "vars": [ "s" , "p" , "o" ] } , "results": { "bindings": [ ] } } I can provide a copy of my fuseki "desc" file if necessary but thought I just check first to see if anyone has any ideas.
