ok last one for today,

I found my last test wasn't really "unit testing", because i did not 
start from an empty V7 db !
I suspect I mixed a V6 conductor (present in virtuoso.db copy) my V7 RDF 
instance !


So I've done another test importing from a graph dump V6 in a clean, 
empty V7 and this time things change a bit as we do not have spurious 
chars at the beginning of the strings when querying ! (but still problem 
with the return of DATATYPE() function anyway) :


select ?graph ?titre (DATATYPE(?titre ))from 
 where {

 GRAPH ?graph {
 
 ?titre

}
}

graph   titre   callret-2

this time I tried with the dump_one_graph_nt procedure from V6

Re: [Virtuoso-users] Fwd: Re: Fwd: Re: Problems using +backup-dump from Virtuoso 6 to Virtuoso 7 with +restore-crash-dump

2015-12-09 Thread Thomas Michaux 

so far I can state two problems :

1/ in a fresh empty V7 build Version 7.2.2-rc1.3215-pthreads as of Nov 
23 2015,

using bulkloader,

ld_dir('/LN_Hupe', '*.nt', 
'http://www.hub.abes.fr/springer/ebooksLN2011/SPR_EBOOK_642_19NOV');

rdf_loader_run();

on a simple file :

 
 "Part III: a sharp result on the 
lack of uniform 
stabilization"^^


will store the object part of the triple as a 
http://www.w3.org/2001/XMLSchema#string literal instead of
http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral (but the string is 
displayed in a correct manner)




2/ something in my virtuoso.db V6 Version 6.1.6.3127-pthreads as of Oct 
19 2012  is causing the same problem when i try to use it as the 
starting point of my V7 installation,
+ it adds misinterpretation of the literal string and decodes it with 
spurious chars.

[Virtuoso-users] Send SPARQL queries via C# ?

2015-12-09 Thread Eng.Bassam 
Hi
I want to query my graphs in virtuoso via C# .Net, I note vi google there
is a dotnet dll to do that, any body has experience to query virtuoso via
C# -send sqprql to virtuoso and iterate query result data set- ???

thanks

Yes, the virtuoso open source version contains a OpenLink.Data.Virtuoso.dll 
which works with Mono.

You can execute any sparql query via the Virtuoso .NET Adapter by prefixing the 
query with the SPARQL keyword as shown here:

http://docs.openlinksw.com/virtuoso/rdfsparql.html#rdfsparqlinline

The resultset is returned as a set of rows which can be iterated over.
