WoT Use Cases - Pre-meeting on ME joint meeting + ITU-T liaison

Guests

Kaz: all of the guests, Chris, Rob and Gyu Myoung, should be aware of the W3C Patent Policy
... we can just confirm that to make sure

all: ok

Rob: I confirm I'm aware of W3C Patent Policy

Chris: yes

Gyu_Myoung: yes

vF2F planning

WoT vF2F wiki

Lagally: still draft, though

<mlagally> https://w3c.github.io/wot-usecases/

Lagally: we WoT WG/IG are generating a Use Cases document
... still need editorial cleanup, though
... working with the other W3C groups and SDOs
... we're the entry point to identify what kind of functionalities would make sense and needed
... so we're collecting use cases based on a template on GitHub

Use Case repo

template for use case description

Lagally: requirements analysis is also ongoing
... we review the proposed use cases and then put them into the HTML document above
... on Wednesday, October 7, we'll have use case session during the WoT vF2F meeting

Oct 7 agenda

Lagally: important topics on liaison with SDOs and collaboration with W3C groups
... we have to talk about who to invite and what to discuss

draft agenda as GitHub issue

Kaz: Rob is thinking of a use case about AR imaging
... would like to generate use case description collaboratively

Rob: using web video map track
... metadata on geolocation as well
... moving images based on the sensors
... use case described on the tutorial
... firstly proof of action
... secondly recording format
... not for AR specifically but can use for video overlay in general
... useful for debugging as well

Lagally: very interesting
... can you do some presentation on Oct 7?
... how long would it take?

Rob: depends on your need :)
... but can provide resources

Lagally: would say 10 mins ;)

Kaz: great

McCool: we're working on geolocation for PlugFest (PoC for interoperability check)
... both static and dynamic geolocation metadata management
... need to think about how to deal with that

Kaz: right, so I invited Rob :)

McCool: what about geospacial work?

Rob: working for the Geospacial group as well

McCool: geolocation metadata is horizontal for various use cases
... we're also talking with the Publishing BG as well
... they're interested in content right management as well
... how to manage privacy for video services is also interesting
... probably relationship there

Kaz: right
... there were several breakout sessions about those points in Lyon, etc.

Lagally: btw, I've added Publishing BG as well to the agenda wiki

PBG agenda as GitHub issue

Kaz: put the URL for the PBG agenda above

Lagally: we'll have the detailed discussion for PBG later during the WoT Architecture call

Rob: I'm also interested in privacy and security
... and search use cases
... metadata within video files
... so interested in blockchain as well
... best practice document on geo is also ongoing
... planning to have a breakout session during TPAC

McCool: we have another WoT TF on Discovery
... searching for geolocation metadata
... talking with some people, e.g., about DNS-based services
... also geo-based metadata
... and security/privacy TF as well
... how to protect the query is important

Lagally: wondering if it would be useful to show use cases from the WoT TFs

<RobSmith> TPAC breakout session: https://www.w3.org/wiki/TPAC/2020/SessionIdeas#Video_Metadata_For_Moving_Objects_.26_Sensors_On_The_Web_.28WebVMT.29

McCool: e.g., NHK is working on media integration use case
... we need to have discussion
... online systems available for PlugFest this week

Lagally: (added geolocation data AR to the new use cases session)

<RobSmith> I'm also interested in discovery for WebVMT

Lagally: what about metadata discovery?
... any other use cases to be ddes?

McCool: feedback from the Scripting API TF and the TD TF?

<RobSmith> WebVMT Golden Tutorial use case: https://w3c.github.io/sdw/proposals/geotagging/webvmt/#goldentutorial

Kaz: possibly some use case based on the recursive Thing Model discussion yesterday?

McCool: some special requirement for privacy management, etc.

Lagally: based on the existing media-related use cases
... we've not created actual requirements yet
... (shows the use cases draft)
... would like to have media experts who could review the proposed use cases

<RobSmith> OGC Testbed-16 Full Motion Video to Moving Features: https://portal.ogc.org/files/?artifact_id=91644#PartFMV

Lagally: would like to capture the discussion today as use cases

Kaz: actually, that's why I'm volunteering to work with Rob to generate a use case based on the template :)

<RobSmith> @kaz Ok. Let's discuss AR use case offline

Kaz: +1 to ask ME guys to review the use cases
... should handle requirements as well within the UC doc

Lagally: let's talk about that during the arch call

Chris: we have little response so far from media companies
... should get real use cases in people's mind
... media companies and CE companies
... would make the media part more concrete
... next
... I'm not sure about the relevance of the things I posted to WoT
... there is work happening on trust
... presentation from Adobe, etc. on Credible Web
... Related to trusted and verified media content: Adobe & the Content Authenticity Initiative presentation from Credible Web CG, https://credweb.org/. And Project Origin https://www.bbc.co.uk/mediacentre/latestnews/2020/trusted-news-initiative

Lagally: we should think about that

McCool: proof based on DID, etc.
... would like to mention a use case for retail
... also multimodal interaction use cases may relevant
... and also smart city ... have real users and applications, also

Kaz: +1

ITU-T

Gyu_Myoung: my questions related to WoT
... discussion on use cases will be in October later
... you can receive some document
... in December, there'll another plenary meeting
... you should be going to get a document from ITU-T, and can respond to that

Lagally: what is the date?
... collaborative discussion next week on Oct 7 would be a good input for that meeting too

Gyu_Myoung: ITU-T meeting in November for our Working Party

Lagally: sounds good
... conversation about what kind of scope you'd think relevant
... suggestion on reasonable topics

McCool: we neet to think about timeline too
... review the ITU-T document and identify the gaps, etc.
... we have a number of ITU-T documents

PR 51 on ITU-T doc

Lagally: you need some more time for this?
... what about liaison doc?
... their Working Party meeting may be going to have more high-level discussions

McCool: the goal should be closing the gaps

Lagally: right

Gyu_Myoung: fine

Lagally: let's use 20mins for ITU-T liaison on Oct 7

Other liaisons

Lagally: we have OneDM and Open Digital Twins
... will talk with Koster for OneDM
... would like to contact Open Digital Twins

McCool: also Hexagon
... smart city geolocation topics
... OneDM is related to CE companies too

<RobSmith> Hexagon are participating on OGC Testbed with me, assuming it's the same company

McCool: believe so

Lagally: McCool, can you take an action to contact them?
... to invite then to the upcoming use cases calls

McCool: would be better to invite them after TPAC

Lagally: ok
... AOB for today?

(none)

McCool: thanks for joining the call today, all!
