I modified rdfbox.c to take out the two (!) checks that object to literals of type geo:wktLiteral with coordinate system URIs. Currently I'm loading a wikidata dump into virtuoso and nothing is complaining (so far). I expect that working with this data will produce query-time errors when trying

So when you implied that wd:Q24227 a wikibase:Item ; wdt:P625 " Point(351.83 -14.47)"^^geo:wktLiteral . had an invalid triple you didn't really mean that. peter On 11/10/2016 10:24 AM, Kingsley Idehen wrote: > On 11/10/16 12:13 PM, Peter F. Patel-Schneider

Is the problem that there is <> around the URI in Point(351.83 -14.47) Otherwise this is in the lexical space for geo:wktLiteral. Although the spec for geo:wktLiteral says that the lexical space consists of an optional URI followed by a geometric value, the

Dear Kingsley, I imagine that Peter is referring to Req 10  All RDFS Literals of type geo:wktLiteral shall consist of an optional URI identifying the coordinate reference system followed by Simple Features Well Known Text (WKT) describing a geometric value. Valid geo:wktLiterals are formed by

Through a process of bisection I found the datum that is not handled by virtuoso. It is wd:Q24227 a wikibase:Item ; wdt:P625 " Point(351.83 -14.47)"^^geo:wktLiteral . i.e., a point on Mars. Is virtuoso supposed to be able to handle other coordinate

Hi: I'm trying to get virtuoso to work with geometry data types. I noticed that the version of virtuoso that I am using requires that the data type names be in ALL CAPS (e.g., POINT). Has this been fixed in the current version of virtuoso? peter
