Meeting minutes
Agenda
conexxus could not join today, further discussion deferred to a future meeting
Publication plan
Lagally: orchestration has come up in several topics, we should probably gather requirements for it
… would be good also to finalize the retail/ECLASS use case
… and we need to look at the Industry 4.0 use case
… and housekeeping, we should see what we can publish by the end of the year
… there are a number of new contributions lately that would be worth including
McCool: propose we stop taking new things end of nov and spend dec cleaning up
… any publication moratoria?
Kaz: dec 21 is deadline for this year
<kaz> December 20, 1200Z: Deadline for publication requests before moratorium
<kaz> December 21: Last publications before moratorium
Kaz: need to send request one day earlier, so dec 20
Lagally: ok, and probably aiming for one week before
… next week's call is still in nov, then we have dec 7 and 14, next would be after deadline
… so just two calls for cleanup and approval
Kaz: although note can be published without worrying the deadline
McCool: although getting things done by the 14th would be a good idea because holidays
McCool: think it makes sense to consolidate conexxus
… regarding gaps, time series data has also come up now and them
McCool: I think in general we need better support for "client" things for various reasons: security, power savings, etc.
… and that leads to needs for shadows (e.g. a service caching state for a thing), and that leads naturally to a service that holds historical data
<kaz> https://
Kaz: media and entertainment (w3c workshop on media production) has some use cases for IoT as well
… many topics, synchronization for instance; also metadata.
McCool: think we should ask NHK for some broader use cases
Kaz: expect some new use case from web-based media production
McCool: I also want to point out that smart tvs are natural iot hubs, already include web browsers, and would be a good way to engage Samsung, Sony, LG, etc.
Lagally: wonder if we have expertise in this group for media
McCool: think we should look into recruitment efforts, starting with a few more joint calls with MEIG
Kaz: have been looking at playback, but lately looking at production
McCool: and home entertainment is perhaps another one
Kaz: but home production is also a thing now
Lagally: but we can start by looking at indoor retail camera
… would be a good step forward
… video streams
McCool: agree that video streams are an important use case we should look at; applies to surveillance, but also home teleconferencing, etc.
Lagally: generic question; specific things like playback, or more general "media handling" goal in charter
Kaz: media handling is really a horizontal use case
McCool: also connects to edge computing and analytics
McCool: suggest we consolidate what we have over the next three weeks, but start an issue to capture thoughts about gaps, requirements, etc
Issues for next publication
Issues marked with "publication-2.0"
Lagally: some discussion during the Editors call as well

PR 140 - Retail use case with ECLASS semantics
Lagally: would merge this
McCool: wondering if the Dataset Exchange WG is still active
Kaz: yes
McCool: maybe we need some clean-up

Lagally: merge this and add clean-up later

Lagally: agree
(merged)
Lagally: let's look at the contributions directory; seems the digital twins uc we just merged might be in the wrong place
