Meeting minutes

Prev minutes

Feb-9

Lagally: (goes through the minutes)

Lagally: any objections?

(none)

approved

Liaisons

Lagally: OPC-UA, etc.
… how to proceed?

OPC UA cooperation proposal

Lagally: wondering about this "purpose"

[[

The purpose is the development of an OPC UA Binding for the W3C Web of Things through an OPC UA Companion specification and mirrored as a W3C Recommendation/Note(?) document.

]]

McCool: this is a propose Charter for the OPC UA side, I thought

Kaz: also think we need to update the description
… we had discussion during the TD call as well
… we should concentrate on simple liaison on datamodel definition for binding and ontology reference for TD, etc.

Lagally: who would improve this?

Kaz: we should ask Sebastian

McCool: yeah, we should leave this to Sebastian
… if we have something normative on the W3C side, we need to think about how to handle that
… note that we can't change our own WoT Charter for the current period

(some more discussion)

Lagally: yeah, I agree we need to identify clear plan
… we should discuss this with Sebastian
… next Linked Building Data CG

Kaz: this is also handled mainly by Sebastian :)

McCool: yeah, need to follow it up with him
… interested in geological information inside buildings

Lagally: do we expect some more additional input?

McCool: use case description, you mean?
… we're talking about geolocation information model, etc., already
… e.g., for smart buildings

(Sebastian joins)

Lagally: (asks Sebastian about the OPC UA topic)
… maybe you can give some comments on your plan?
… how/who would create the target document mentioned here?

McCool: someone needs to take the lead

Sebastian: originally expecting a joint group but we had some discussion during the TD call
… about the expected collaboration
… the idea should be more OPC UA's taking lead for their work
… and we can follow their work
… we expect to hold a dedicated call on further discussion related to liaison

Lagally: think we should review their specs, etc.

Sebastian: my question is who would be actively working on the collaboration

Kaz: I'll create a doodle poll for further discussion quickly

Lagally: ok. let's move on then
… next ITU-T SG 20
… unfortunately, not available today
… plan to have a follow-up discussion during the vF2F in March
… the topic is gaps and next steps based our summary

ITU-T use case summary

McCool: agree

Lagally: btw, regarding the Linked Building Data CG
… any plan to create use case descriptions?
… would like to publish the first draft of the WoT Use Cases within a few weeks

Sebastian: unfortunately, not able to join the use cases call for a while
… so not really sure about the plan

Lagally: we had a joint call with them

Sebastian: will ping the CG guys

Lagally: great

Kaz: have been talking with the ECHONET guys
… will talk with them again on March 5
… will get back to you all
… possibly could have input for future use cases

MR 97 - add edge-computing.md into index.html

MR 97

Lagally: would merge this

(merged)

MR 86 - Update Smartcity Dashboard UC

MR 86

Philipp: added comments

Philip Tran's comments

Lagally: can make these changes

McCool: updates with missing references as well

diff

Philipp: what kind of references?

McCool: existing standards, etc.
… e.g., OGC's work

Lagally: why don't we merge this and McCool can make editorial changes

McCool: ok

(merged)

MR 94 - Focus AR/VR Guide use case on AR

Lagally: work on AR/VR originally proposed by Rob and Kaz
… updated by McCool

McCool: would suggest we merge this

Christine: the use case is actually AR guide. right?

McCool: VR might not require geolocation information though AR does
… that's why focus on AR here

Christine: ok

Lagally: (goes through Rob's comments)

Rob's comments

Rob: there is a guidance on responsible use case of spatial data by the SDW IG

The Responsible Use of Spatial Data

Rob: related security/privacy issues as well

McCool: will look at it

Rob: tx

Lagally: would make sense to extend the security/privacy section?

McCool: that's my plan :)

Rob: great

Lagally: can we merge this MR itself and then work on the comments?

McCool: that's fine

ka: I'm OK too

(merged)

MR 90 - Joint activity for a standardized OPC UA Binding

MR 90

Sebastian: this is the main README but not sure if it's still relevant
… should have the discussion during the separate call

Lagally: OK to keep it open then?

Sebastian: ok

Linked Building Data CG (revisited)

<sebastian> https://github.com/w3c-lbd-cg/wot-usecases/blob/feature_UpdateWithBim/USE-CASES/W3C-LBD-CG.md

<sebastian> https://github.com/w3c-lbd-cg/wot-usecases/blob/feature_UpdateWithBim/USE-CASES/W3C-LBD-CG.md

Sebastian: got response from the Linked Building guys
… they're working on a use case description

Lagally: great

WG Note planning

Lagally: basic timeline

[[

- consolidated draft in next call

- two week's review

- publication approval in vF2F

]]

Use Cases draft

Lagally: wondering about if we could have dedicated contributions from the co-Editors

McCool: we'll have the PlugFest next week
… should prioritize the work items
… how to bring it to the vF2F?

Lagally: would have email discussion

Kaz: given the tight schedule, would suggest we make the TF resolution today instead of the next UC call in 2 weeks
… and bring the draft to the main call tomorrow on Feb 24
… we can add some note mentioning there might be some minor changes

<Mizushima> +1

Lagally: asking the whole group for review asap is good
… but would like to confirm the draft is ready during the next call in 2 weeks

McCool: we need to think about when to have use case discussion during the vF2F

Lagally: ok

let's talk about that during the main call tomorrow
