2010	Pull Requests	All	More topological relation equivalences (#532): TH implemented suggestions from Vladimir Alexiev; MP and NC to review.

Discussion on how to define default parameters in the specification. NC suggested reviewing OGC Features API conventions; group noted flexibility if conventions are clearly explained. Reference: https://docs.ogc.org/is/17-069r3/17-069r3.html NC questioned whether this was the only default parameter; TH confirmed it currently is. NC noted default parameters might have been used instead of defining metric variants; TH to review wider set of GeoSPARQL functions for applicability. Intersection Geometry Vocabulary (#535); closes #239. NC questioned need for a class for intersection geometries and suggested provenance could be used to indicate derivation. Including common non‑SFA functions (#536); TH added missing functions; requires review. Geocoding Vocabulary (#537); TH requested review and comments; NC noted contact with OGC Naming Authority.
