See:

http://nl.dbpedia.org/sparql?default-graph-uri==define+sql%3Adescribe-mode+%22CBD%22%0D%0Adescribe+%3Chttp%3A%2F%2Fnl.dbpedia.org%2Fresource%2F2_Broke_Girls%3E=text%2Fhtml=3=on

DESCRIBE is sparsely specified in the SPARQL specs so you need to use a
pragma. In this case I used:

define sql:describe-moe "CBD"

Where CBD is for Concise Bound Description.

Also, if you open a resource in the classic interface (Pubby the extra
triple is shown, i.e foaf:depiction), but when you open the same
resource in the new interface no extra triples is shown.

That works fine, as stated before; when the graph is specified in the
sparql query the results are as expected.

But take f.i. a resource out of these results and ask a DESCRIBE the
foaf depiction triple is not presented for the resource:

What happens when you try:

If that's fine, this its down do you not using: GRAPH ?g in the dataset
modifier (body) of your sparql query.

Re: [Virtuoso-users] loaded data doesn't bind to graph specified

2017-01-26 Thread Roland Cornelissen

Hi Hugh,

I think the load method used for nl.dbpedia is TTL_MT() in a script of
Dimitris. I think that is different from ld_dir(), but I tried ttl_mt()
also later with the same results.

I just updated the VOS instance to the latest version from Github and
tried again to load the data. Again the same results...

Re: [Virtuoso-users] Running to VOS with one virtuoso.db

2017-01-26 Thread Hugh Williams

Hi Pasquale,

What is the purpose of running two Virtuoso instances, is this for setup access 
for SPARQL or SQL storage ?

The easiest way to start multiple Virtuoso database instances on the same 
machine is to create two separate databases with a “virtuoso.ini” file on each 
set to use unique SQL & HTTP ports and then start each in the separate 
directories with a lock file for each …

Re: [Virtuoso-users] loaded data doesn't bind to graph specified

2017-01-26 Thread Hugh Williams

Hi Roland,

Is this not the same method you have loaded DBpedia NL datasets in the past ? 
In which case what is different with this new dataset load ?

What other graphs are in the Quad Store:

SPARQL SELECT ?g COUNT(*) { GRAPH ?g {?s ?p ?o.} } GROUP BY ?g ORDER BY 
DESC 2;

and can you query and of the other graphs with the name specified in the 
“Default Data Set Name” field (from)

Also, does the following return results when run from the isql command line 
tool:

sparql select * from   { ?s foaf:depiction ?pic 
} limit 100;

[Virtuoso-users] Running to VOS with one virtuoso.db

2017-01-26 Thread Pasquale Di Donato

Hi all

I wanted to run 2 Virtuoso Open Source instances on one virtuoso.db, but it
seems not possible since when the first instances is run then a lock file
is created for the DB.

Any hint here or is this not possible with the Open Source Edition?
