Geometry^c

IRI	`http://www.opengis.net/ont/geosparql#Geometry`
Is Defined By	http://www.opengis.net/ont/geosparql#
Description	The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types. GeoSPARQL is Copyright (c) 2012 Open Geospatial Consortium, Inc. All Rights Reserved. http://www.opengeospatial.org/ogc/document.
