Re: [Virtuoso-users] Multiple quad tables

at spawned this thread since it doesn't involve completely separate table namespaces. Maybe it could be done with the clustering, where data held in one node has the modify bits removed? Else solve it at the application level... Cheers, -w -- William Waites<mailto:w

Re: [Virtuoso-users] Support for Lines and Polygons in Virtuoso's Geospatial Extensions

2010-12-04 Thread William Waites
necessarily the best answer (in an ideal world we'd have proper 3 dimensional coordinates instead of 2.5) but it's enough to get started -- it would make Virtuoso a viable alternative to PostGIS or Oracle for geodata. Cheers, -w -- William Waites http://eris.okfn.org/ww/foaf#i 9C7E F636

rvices and couriers, the list goes on... One challenge is that we still have no consensus on how to express this type of data and these operations in RDF, but that's a separate issue from support in the database itself. Cheers, -w -- William Waites http://eris.okfn.org/ww/foaf#i 9C7E F636 52F6

Hi all, Following up on the previous thread [0] about getting literal values out of an ODBC connection for SPASQL queries, I've managed to make a preliminary patch for pyodbc that does this [1]. I noticed two issues when doing this. First, Virtuoso OS 6.1.2 seems to only give the proper datatype
