With the W3C WGS84 vocabulary you can write: @prefix geo: <http://www.w3.org/2003/01/geo/wgs84_pos#> . @prefix : <#> . :bob a geo:SpatialThing ; geo:lat "52.5196143" ; geo:long "13.4065603" . So the resource with the URI :bob is both the "feature" and the "geometry". In other representations (NeoGeo, GeoSPARQL), you would identify two separate resources: @prefix geo: <http://www.w3.org/2003/01/geo/wgs84_pos#> . @prefix : <#> . :bob a :Feature ; :geometry _:bnode . _:bnode a :Geometry , geo:Point ; geo:lat "52.5196143" ; geo:long "13.4065603" . The URI :bob now represents the "feature" resource, and the blank node _:bnode represents the "geometry" resource. I wouldn't know how to write OWL axioms to map the two modeling choices though. Best regards, Andreas.
