OGC Membership approves Common Query Language (CQL2) as an official OGC Standard
CQL2 is a filter grammar supporting both text and JSON encodings that can be easily integrated into software applications.
GeoSPARQL – A Geographic Query Language for RDF Data
Overview
The OGC GeoSPARQL standard supports representing and querying geospatial data on the Semantic Web. GeoSPARQL defines a vocabulary for representing geospatial data in RDF, and it defines an extension to the SPARQL query language for processing geospatial data. In addition, GeoSPARQL is designed to accommodate systems based on qualitative spatial reasoning and systems based on quantitative spatial computations.
The GeoSPARQL standard is actively maintained. To follow its progress, visit the public Github repository located here: https://github.com/opengeospatial/ogc-geosparql.
