The draft Abstract Conceptual Model for Time (OGC23-049) was approved for public release for comment by the OAB earlier in the day, pending corrections from Chuck Heazel and an improved diagram from Greg Buehler.

There was a request to indicate the relationship with W3C OWL Time in any press release.

Simon Cox (OGC Fellow 2023-2024) suggested more figures and examples would make the document easier to understand.

There were some editorial corrections from Carl Reed (OGC Staff).

Ron Tse suggested that the Timeline / Timescale distinction could be considered for incorporation into the next verson of ISO DIS34000 Vocabulary.

Chuck had tried mapping the concepts to ISO19111, ISO 19108, ISO DIS34000 and the W3C OWL Time with very encouraging results.

The only Best Practice identified was to use IETF RFC 3339, using UTC (Z time) rather than any other timezone or daylight saving corrections to timestamp resources. This has been adopted in some recent OGC standards.

Date of Next Meeting: in about two weeks, probably 11 Oct 2023.
