| Description | The File Ontology for Geometry formats (FOG) provides geometry schema specific relations between things (e.g. building objects) and their geometry descriptions. These geometry descriptions can be (1) RDF-based (e.g. using specific ontologies such as GEOM, OntoBREP, etc.), (2) RDF literals containing embedded geometry of existing geometry formats and (3) RDF literals containing a reference to an external geometry file. |
