GeoSPARQL
GeoSPARQL is a model for representing and querying geospatial linked data for the Semantic Web. It is standardized by the Open Geospatial Consortium as OGC GeoSPARQL. As of version 1.1, published in 2024, a validator for RDF data to meet GeoSPARQL patterns is also supplied, using SHACL as well as a Simple Features hierarchy of geometry classes and a vocabulary of GeoSPARQL rules and functions.
