Time Item Who Notes
2043 Intro JA Call for Patents
  • None known
Roll Call
  • Attendees recorded in minutes
  • Attendees confirmed vocally
2044 Run through of Pull Requests JA
  • NC
    • adding a bunch of shapes [#173](https://github.com/opengeospatial/ogc-geosparql/pull/173)
    • Key questions:
      • How should we manage shapes that are not part of the standard i.e., look at the spatial data rather than just the structure.
    • Resolutions
      • We will create a folder for useful scripts, to enable people to continue working on things that are not part of the specification. This work can be maintained by a community group.
    • To Do:
      • MB to complete his additions
      • JA to raise the community group at Geosemantics DWG.
      • NC to change the domain of scalars to SpatialObject from Feature.
      • TH to create issue for discussion on Shape 1. Done: [#177](https://github.com/opengeospatial/ogc-geosparql/issues/177)
    • DISCUSSION:
      • Shape 1: Conflict relating to whether there should be only one serialization for a geometry. FK: looks like it goes beyond the scope of the ontology.
      • Should hasLength, hasArea, etc., have constraints on cardinality e.g., A Feature can have only one area? No. But we would like to shift the Domain of them to SpatialObject to enable Geometry’s to have hasLength, etc.,
    • TH
      • Modeled conformance classes [#176](https://github.com/opengeospatial/ogc-geosparql/pull/176)
      • To do: NC and FK to review the PR
    • FK
      • Update geo.ttl: redefine ontology terms for DGGS [#136](https://github.com/opengeospatial/ogc-geosparql/pull/136)
      • To do: NC to take a look and comment on this PR, re currency and relevance.
2154 GeoSPARQL Compliance Benchmark TH
  • Link: https://www.mdpi.com/2220-9964/10/7/487
  • Wikipedia article for GeoSPARQL was a bit outdated. TH has made some updates, but we should all take a look.
