Time Item Who Notes
2005 Roll call and call for patents All Roll call completed. Call for patents held. Quorum confirmed.
2010 Pull Requests All
  • Ran through pull requests.
  • Issue raised regarding GeoSPARQL implementations performing geometry transformations across different CRSs (e.g. for distance calculations).
  • Noted that use of a bridging CRS (such as WGS84) can introduce artefacts.
  • Group agreed this behaviour should be left to implementers, but that end users should be made aware of the methodology used.
  • Discussed adding information to the service description to improve transparency.
