Re: [Virtuoso-users] Access nonlocal Virtuoso instance

Hi Alexander, It is unclear to me as to what your problem is. I don't understand what you mean by "I have installed Virtuoso and set System DSN using state white ip address." What "System DSN" is this, for and ODBC connection ? Ultimately, it seems you are saying that remote connections to t

Re: [Virtuoso-users] Access nonlocal Virtuoso instance

Hello Alexander, 1. As a common rule there should be no masquerading routers between client and server, so if you're using an ISDN, ADSL or long-range wire modem then check that it is in some transparent mode (router only or IP-over-ppp or the like, but not a firewall with DMZ (demilitarized zone)

Hi Alexander, If you can point out an such incorrect examples in the documentation then we can fix them. Do we aware that "and" and "or" act as a logical operators in bif:contains and thus do not require the extra quoting in string searches, so you can have: bif:contains (?text, "hello and wor

Hi Hugh, Thank you, that helped. But there are a lot of examples at documentation that use just double quotes... Regards, Alexander 2010/3/4 Hugh Williams > Hi Alexander, > > Try the following: > > SELECT * WHERE { ?s ?p ?o . ?o bif:contains "'Some non english literal'" } > > Note the addition

Hi Alexander, Try the following: SELECT * WHERE { ?s ?p ?o . ?o bif:contains "'Some non english literal'" } Note the addition of single quotes within the double quotes which is how Virtuoso handles phrases in bif:contains. Best Regards Hugh Williams Professional Services OpenLink Soft

Re: [Virtuoso-users] Syncing a graph between two instances

Hello Aldo, I did not retest it for ages, but http://docs.openlinksw.com/virtuoso/rdfsparql.html reminds syntax [DML]* LoadAction ::= 'LOAD' PrecodeExpn ( ( 'IN' | 'INTO' ) 'GRAPH' ( 'IDENTIFIED' 'BY' )? PrecodeExpn )? Thus, on source site it's enough to have some redirect from some IRI to CONS

Hello Martin, Consider upgrade to some recent version. If that is impossible then I need an exact server version number to check if I can create a safe patch specifically for that version. Best Regards, Ivan Mikhailov OpenLink Software http://virtuoso.openlinksw.com On Thu, 2010-03-04 at 18:16

Re: [Virtuoso-users] Syncing a graph between two instances

Here are some thoughts: - Use remote SPARQL execution ( not in V6.1, right? ) - Issue SPARQL construct to remote instance's sparql endpoint via HTTP. Parse result and replace graph Of this does not scale as well as moving TTL files around. But for 90% of our use cases it should work just fine. T

[Virtuoso-users] SPARQL query returns blank nodes as literals in some cases

[Virtuoso-users] Syncing a graph between two instances

Hi, This is a common requirement that I usually solve in an ad-hoc manner. Say I have an instance V1 with graph A. And then I have a (remote) instance V2 with graph B. The requirement is: I want graph B to remain sync'ed to graph A over time. It needn't be automatic, but it should be cheap and ho
