2036 Run through of Pull Requests JA
  • TH
    • [#176](https://github.com/opengeospatial/ogc-geosparql/pull/176)
    • Key questions:
      • URIs for requirements. Should we be publishing with new URIs, or reuse the existing ones, or both.
    • Resolutions
      • URIs reflect the head i.e., the latest, a combination of 1.0, 1.1, and beyond.
      • We want to reuse existing URIs
      • We don’t want to needlessly create new URIs
  • MB
    • [#173](https://github.com/opengeospatial/ogc-geosparql/pull/173)
    • DISCUSSION:
      • Shape 1: Conflict relating to whether there should be only one serialization for a geometry.
      • Shape 2: Some people are storing Geometries with no incoming links. It’s not a problem as we can deactivate this shape if it is an issue. The bigger issue is the limit on the max constraint. Keeping this does not promote the reuse of Geometries that we’re keen to see more of. Discussion landed on removing the constraint.
      • Shapes 16-20: Simplified regular expressions for WKT, GeoJSON, KML, DGGS, GML are preferred to anything that delves into the shape in too much detail. Main goal is to ensure that the serialization property matches the data (i.e., gmlLiteral doesn’t have a KML serialization).
      • Shapes 31: geo:hasSerialization should never be asserted - to be removed.
    • Expecting more work to be done by the next meeting, but not until the second week.
  • NC:
    • DGGS still needs an example. Auspix example was removed, but will be readded to the spec and not to the ontology.
2100 Run through Issues All
  • Issues completed were moved to Done
  • Two In Progress Pull Requests were added to In Progress
