Environmental Data Retrieval API SWG Meeting 104

(Meeting postponed from 2023-08-10 because of holidays)

14:00 UTC (08:00 MDT, 10:00 EDT, 15:00 BST, 16:00 CEST, 22:00 CST, Friday 01:00 AET)

Agenda

• Agree Agenda and IPR Call
• Minutes/Notes of previous meetings

Status: EDR

Progress in the last month:

• EDR API Specification:
  • Progress on V1.1 Text and Schemas in publishing, all issues closed.
  • Progress on V1.2 (PubSub)
    • V1.2 Master branch aligned with V1.1.0
    • PubSub SWG revised Charter agreed, to be formally voted. Good represention of Charter members from across OGC
    • EDR API SWG pursuing faster deadline
    • Several other topics identified and in GitHub projects: V1.2 improvements, Part 3: Summary stats and aggregation
• Outstanding Issues:
  • V1.2 PR needs updating for Part 2 rather than optional Core Conformance Class
• Outstanding Pull Requests:
  • Only V1.2 or V1.0.2 branches outstanding - should be deleted
• Compliance Test Suite: V1.1 delayed until at least 3Q2023
• API coordination:
  • Sprint Oct/Nov 2023, London
  • On-going with Connected Systems and Coverages
  • Need to engage with GeoDataCube
• Update other Documentation on GitHub:
  • Wiki pages, Readme to outline PubSub, mock-up demos, draft standard pages, etc

Plans for next month:

• Progress PubSub (Part 2)
• Progress V1.2
• Start work on Summary Stats and Aggregation (Part 3)

Outreach:

• Dates for regular telcos
• Consider review of Testbed 19 Engineering Reports ('geospatial in space')
  • https://docs.ogc.org/per/23-011r1.pdf
  • https://docs.ogc.org/per/22-038r2.pdf

Longer Term Plans:

• Non-breaking changes and enhancements: Tentative Version 1.3: Streaming response, maybe replaced by PubSub
• Version 2.x: Not envisaged, unless large scale re-alignments of all APIs planned. Certainly later than V1.3

Risks:

• Divergence of PubSub SWG Spec and EDR Part 2 spec
• Revamp and retro-fitting of schemas etc from API-COverages might necessitate V2.0 with breaking changes

Any Other Business:

Date of Next Meeting: Thursday, 7 September 2023, 14:00 - 15:00 UTC (08:00 MDT, 10:00 EDT, 15:00 BST, 16:00 CEST, 22:00 CST, Friday 01:00 AET)
