Issues |
All |
- Issue discussed: https://github.com/opengeospatial/ogc-geosparql/issues/608.
- Consensus that expressing full geometry contents as pure RDF would be extremely verbose and difficult to work with.
- Agreement to discuss approach further with Peter at the Geonovum meeting.
- General agreement that more geometry types could be useful, but concerns remain about encoding full geometry components in RDF.
- Example referenced: https://rdf.bg/geometry.ttl.
