Pull Requests |
All |
- Extend hasGeometry to allow for GeometryCollections (#525).
- Union expressions in range expressions are forbidden in OWL2 RL; need for a concrete superclass identified.
- NC suggested
:Geometry :havePart :Geometry with an intermediate Geometry instance. - Alternative proposed: make GeometryCollection a subclass of Geometry.
- NC to work on writing up a subclass proposal.
- Latitude and Longitude Functions (#526): function defined only for points.
- TH updated specification to state the function applies only to points.
- Discussion on projected CRSs, axis order differences, and limitations of getX/getY.
- JA suggested easting and northing as applicable to both projected and geodetic systems.
- [Alignments] Isolating alignments from main specification (#527): waiting for input from OGC.

Other Business |
All |
- NC and TH reported on a talk given to the Building Group.
- Group expressed interest in specific handling of 3D and potential validation of a candidate scheme.
- Request for geometries referencing external files due to large 3D geometry literals.
- NC to look at formalising geometry literals stored in external files.
- Discussion on ISO Group on Ontology Maintenance and possible ISO serialisation of ontologies.
- Example referenced: https://github.com/ISO-TC211/GOM/tree/master/isotc211_GOM_harmonizedOntology/iso19111/2019
