[Virtuoso-users] Virtuoso and spatial extensions / spatial support

After Postgresql, the Mysql database server has support for spatial extensions since version 5.1 [1], by implementing a subset of the SQL with Geometry Types environment proposed by OGC. [2] Information about spatial features within Virtuoso could not be found at openlinksw.com, that why th

Bob, There should be a graph with IRI: http://localhost:8890/DAV/home/user3/rdf_sink/ in the Quad Store. Thus you can get the data from the uploaded file with the following query: select distinct * from where {?s ?p ?o} You can execute it fro

Re: [Virtuoso-users] inference context error

Rumi, Seeing an explicit ":80" flying around makes me wonder if there is a configuration step missing during installation, or perhaps further clarification ( for example, make sure to set A, B, C ). Specially if this results in unexpected behavior further down the road. We have not done anything

I tried again with "Allow DAV Logins" checked, and for good measure I added SPARQL_SELECT, SPARQL_UPDATE, and SPARQL_SPONGE to the list of Selected Account Roles. (Whenever I add "SPARQL_SPONGE it tells me that SPARQL_SPONGE is already assigned, even when I don't see it in the list of assigned

Hi Bob, For point 2 when you created the new user account was this a DAV enabled account which is required for the data insertion. Their is an option in the conductor to enable DAV logins when you create a new account. Best Regards Hugh Williams Professional Services OpenLink Software Web

Hi Cristian, Could you please check: 1. in virtuoso ini file what is the value of the URIQA - DefaultHost * if the htttp is on port 80, then this port you must not use in the default host, as cname in this case is without the port. 2. You can check what returns this: sparql select count(*)

I'm not having much luck with the RDF insertion methods that I've tried from at http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtRDFInsert. I'm using Windows XP. 1. In the "SPARQL Insert via /sparql endpoint" section, the INSERT query in step 1 did not work at http://localhost:8890/
