Hello! I'm trying to use virtuoso storage for Redland, but creating a new storage with "librdf_new_storage" fails:
storage = librdf_new_storage(rdf_world, "virtuoso", "db1", "dsn='VOS',user='cordawyn',password='secret'"); ... librdf error - storage 'db1' not found I have Virtuoso Open-Source 6.1 running at a local machine (checked it via the web interface), unixodbc-2.2.14 and librdf0-1.0.14 (all running on Ubuntu 12.04, x64). "VOS" DSN is available, as reported by "odbcinst -q -s", the user credentials are correct. What am I doing wrong? Could it be that librdf is not compiled with odbc support? "ldd" does not report any dependencies on *odbc*, but perhaps there shouldn't be any in that list? <rant> I'm new to Virtuoso and don't understand what "storage name" (3rd argument of librdf_new_storage) means. The descriptions at librdf.org and virtuoso.openlinksw.com (which seem to be just slightly modified copies) don't help much, sorry ;-) And those extra options (that are never used in the examples, as far as I can see) just add to the confusion: I mean "database" and "host". Okay, they are sort of intuitive, but they're never used in the examples, and the examples still "work". Also, the example at virtuoso.openlinksw.com says: storage=librdf_new_storage(world, "virtuoso", "http://red3";, "dsn='Remote Virtuoso',user='demo',password='demo'"); so... storage name is "http://red3";? What would be the "host" option then? </rant> On a somewhat related note, samples at virtuoso.openlinksw.com don't work: rdfproc -r xml -t "user='dba',password='dba',dsn='VOS'" gr query sparql - "SELECT * WHERE { ?s ?p ?o }" rdfproc: invalid argument `xml' for `-r / --results' Try 'rdfproc -r / --results help' for a list of valid query result formats Try `rdfproc -h / --help' for more information. rdfproc -r help rdfproc: Valid query result formats are: xml SPARQL XML Query Results json SPARQL JSON Query Results table Table csv Comma Separated Values (CSV) tsv Tab Separated Values (TSV) html HTML Table turtle Turtle Query Results rdfxml RDF/XML Query Results Could anyone help?
