using:
DB.DBA.TTLP_MT (file_to_string_output
('/home/virtuoso/share/virtuoso/vad/spatialTest.nq'), '',
'<http://localhost:8890/DAV/dbpedia>',512);
After which I ran the following query:
SQL> sparql select ?place ?nplace (( bif:st_distance( ?long,?nlong) )
AS ?distance) WHERE {graph ?g1{?place
<http://www.opengis.net/ont/geosparql#asWKT> ?long} graph ?g4{?nplace
<http://www.opengis.net/ont/geosparql#asWKT> ?nlong}};
Which gave me the following error:
*** Error 22032: [Virtuoso Driver][Virtuoso Server]GEO..: Function
st_distance() expects a geometry as argument 0
Can someone please guide me as to where am I going wrong and how I run
spatial join queries in Virtuoso?
