Yep Done using the BuildingBlocks we will ensure such components can be integrated with other specifications using a common mechanism. BBs do many things - the ones that matter here are: 1. link the schema to the conceptual model (using an ontology versions of the CM) 2. provide transparency around the dependencies 3. Provide examples and validation tools for each component 4. Provide links to your normative schemas and other resources in a standardised way (every spec is different 🙁 ) So its not an either/or - its "let me help you realise this goal - heres some tools ready to go..." And a draft we can evolve to match your current spec: https://opengeospatial.github.io/geopose-bblocks/bblock I will run tutorial and editing sessions to get this up and running if its not 4am...

I believe that what you propose as the BBs is what the SWG is now calling the "GeoPose Components.” See these slides<https://docs.google.com/presentation/d/1e28blobnrG9zYl_8VyhjyWHs2ZqiW2z5MS94dxHMBSU/edit?slide=id.p1#slide=id.p1> and these slides.<https://docs.google.com/presentation/d/1YLFjEXiKAGo4_o4EymYXlsTnkf9VjTkSk6QL3eRTOlY/edit?slide=id.p1#slide=id.p1> As you will see on our GeoPose 1.x roadmap<https://geopose.org/CallForContributors.html> (and seek volunteers to contribute to) we are also separating the JSON encoding<https://github.com/opengeospatial/geopose-json-encoding> from the CM specification<https://github.com/opengeospatial/GeoPose-cm>.

Let me know if I can help further. Always willing to run training on this. There is now a tutorial, and will be creating videos to help this year as well.

Many thanks for these pointers and suggestions. @Rob A Any questions? 100% agreement that posting future GeoPose discussion issues directly to the SWG mailing list at geopose.swg@lists.ogc.org<mailto:geopose.swg@lists.ogc.org> will get the best visibility.

I notice that the OGC Building Block wrappers refer to the draft GeoPose spec. I recommend that you update these to reference the OGC GeoPose Standard document [1] instead. 2. WebVMT is a current work item in scope for SDW - as previously agreed in the rechartering discussion [2]. SDW published a W3C Group Note [3] (OGC 23-027) in September 2023. Development is ongoing in collaboration with several OGC SWGs and W3C WGs including GeoPose, Moving Features and WICG DataCue [4], though these disparate topics are drawn together in SDW. 3. On the subject of ‘alignments’, a new heading attribute was developed and prototyped in Testbed-19 [5] which is aligned with GeoPose. This is designed to integrate with HTML and includes features such as heading and missing data which are beyond the current scope of GeoPose 1.0. WebVMT heading data were published in the T19 Hillyfields Bubble repo [6] under an open licence and this feature was developed further in Testbed-20. 4. I recommend posting future GeoPose discussion issues directly to the SWG mailing list at geopose.swg@lists.ogc.org<mailto:geopose.swg@lists.ogc.org> for best visibility. Thanks. I’d welcome the opportunity to present recent WebVMT progress and future plans to help ensure that the Group is kept up to date. Please let me know when the next SDW Plenary meeting is scheduled, and I look forward to hearing from you soon.

Continued participation in OGC Testbed-20 GIMI [8] to ensure that proposed design for GIMI video timed metadata is aligned with existing formats. 2. Next Steps i. Create short video summary of OGC Testbed-20 GIMI maritime and aerial use case results for OGC YouTube channel [9]. ii. Continue participation in OGC Testbed-20 GIMI [8] to ensure that proposed design for GIMI video timed metadata is aligned with existing formats. iii.
