scribebick: kaz
Lagally: (goes through the agenda on
the wiki)
... anything else to be added?
(none)
Lagally: link to the home network use
cases added here
... anything to be updated about that?
Chris: no changes
Lagally: ok
Lagally: no objections so far
... (goes through the minutes)
... joint discussion with the Singapore Govtech guys
... then discussed use cases from the first WoT Charter
period
... anything to prevent us from publishing the minutes?
(none)
Lagally: then approved
<mlagally> https://www.w3.org/WoT/IG/wiki/F2F_meeting,_16-19_March_2020,_Online
Lagally: (goes through the virtual f2f
wiki)
... a couple of goals here
... potentially we need some more additional slots
... at the moment, we have 20 use cases on GitHub
... would choose some of them based on a criteria
Lagally: we should clarify the
viewpoints like business-oriented, etc.
... should send the proposal to the whole group
beforehand
... whole work to be evaluated by contributions
... let's go back to the virtual f2f agenda
scribe: lifecycle (including
privacy considerations)
... one more thing I want to revisit is cross-protocol
interaction
... related to the discussion on WoT Profile
... would like to have one additional hour for that
... will talk with McCool and Sebastian about that
<scribe> ACTION: Lagally to send the roadmap to the group and ask the Chairs to put the WoT Profile topic to the virtual f2f agenda
Lagally: the question is how to deal with the topic, what would be the realistic goal :)
<scribe> ACTION: Lagally to propose we make the Architecture call 1 time one hour later
Lagally: let's do a doodle poll for that
Lagally: improve integration of use case section and structure of normative sections
Kaz: AC review results are Member-only, so we should not put the exact quote from their review but would be better to put the summary point here
Lagally: good point
... (fixed his comment for issue 446)
Lagally: we're discussing possible use cases for retail business
Lagally: Toumura-san kindly took action to improve the diagram
Lagally: would reflect this diagram to
the press release as well
... the other PRs are deferred to the next call when Govtech
guys and Connexus guys are available
Chris: although we invited Members,
not many have responded so far
... I know NHK are working actively within the WoT IG/WG
already
... maybe you've got some input from them
Lagally: yeah, PlugFest demo during TPAC 2019
Kaz: I think this is a "Chicken and Eggs" problem, we would like input from MEIG guys to generate a use cae description but they would like our proposal before joining the discussion
... maybe as a Team Contact of both the WoT WG/IG and the MEIG, who have been participating in both the group's discussions, I can generate some initial ideas as a starting point
Lagally: how about starting with the home network use cases?
Lagally: Use case for TD to describe media streaming protocols
Chris: media distribution across multiple devices
Lagally: also had been working on media distribution, e.g., at DVB
Chris: having use cases which
people actively work on
... all I can do is reviewing the use cases and see if there is
still gap
... there are several use cases which are still
unsatisfied
... we would have a joint call about an interoperability
layer
... to describe the capability of mapping
... maybe some of the use cases include exchanged information
via multiple protocols
... need to see if we need higher mechanism than the existing
protocols
... e.g., for synchronization
... but we've not been doing interoperability discussion
... not sure about the desire for vendor-neutral
synchronization
... think we should reach out the Member a bit more to see the
need
... to develop systems using WoT
Lagally: got some interesting points
Chris: the other things we discuss
offline is about smartspeaker devices
... would face issues for home automation integration
... voice interaction is another interesting area
Lagally: are those vendors participating in the MEIG?
Chris: yes, though not regularly
participate in the calls
... note that the divisions are different
... we're interested in providing content via those devices
Lagally: there is a common format for
interoperability like blu-ray
... on the broadcaster side, they also work on common format
for contents
... interoperable media format and hardware format
... would be nice to have some common format for smartspeakers
from multi-vendor as well
Chris: that's true
... difficult to support interoperability based on different
formats
... can speak only based on my organization but
... there is an area of production technology within studio
environment
... everything is moving to the Internet-based technology
... how to discover media source available, etc.
... also how to consume it
... you would have different vendors
... so an interoperable layer is required
... happy to follow up with my colleagues
Kaz: regarding "voice interaction", we had a breakout session during the TPAC 2019 in Fukuoka
... based on that discussion, I've been working with the W3C Strategy Team to prepare for a possible W3C workshop on voice interaction
... will put the initial ideas on the Strategy Funnel GitHub repo
Lagally: ok
... one question would be how to proceed
... we have BBC and NHK as possible attendees
... what other broadcasters to be involved?
Chris: IRT from Germany?
Lagally: interesting :)
Chris: their AC rep is Andreas Tai
Lagally: ok
... let's go back to NHK
... we should generate an initial use case
... thought they also provided some presentation during
TPAC
... we could elaborate what is in their mind
Chris: the other organization in my
mind is Comcast
... they're active within MEIG
... we didn't have enough time today but we should look into
the existing standards on discovery, e.g., DLNA
... specific protocol included there
... capability discovery and metadata stuff
... that's an area to be explored
Kaz: +1
Chris: anything you expect from
me?
... can reach out the MEIG guys
Lagally: please do so
... also you can introduce me to IRT :)
... regarding NHK, Kaz is the main contact
... how about asking them to see their slides for TPAC
... and see what could be extracted for possible use cases
Kaz: ok
... will talk with NHK to ask them to see possible use cases
based on their slides at TPAC
... and also would create an issue (or issues) for possible use cases
Lagally: please do so
... including the voice agent as well
... let's put it on the next week's agenda to revisit this
topic
... would be great to get input from expected stakeholders
Chris: sounds good
Lagally: we've covered a lot of stuff
today
... call 2 would focus on the other topics
... thanks a lot!
... aob?
(none)
[call 1 ends]
Lagally: (goes through the agenda)
... need to shuffle some of the topics given today's participation
Lagally: approved
McCool: ok
Lagally: talked about the virtual f2f
agenda during call 1
... would see opinions/ideas from Singapore Govtech, NHK,
etc.
... to identify right requirements
... sent a message to the group about that
... and lifecycle discussion
McCool: we have onboarding during the
security session
... we would be able to use Thursday as well because we won't
travel for the IETF meeting
... we could use some time for lifecycle discussion
(some more discussion on when to have lifecycle discussion)
McCool: if you don't attend the onboarding session, would be problematic
Lagally: discovery as well?
McCool: what is your conflict?
... and what topics require your participation?
Lagally: we should not occupy the entire week
McCool: if some of the sessions are very important for you, we could move them
Kaz: so you're interested in architecture, discovery and onboarding
Lagally: right
... and 4pm CET would be the latest for JP people
McCool: note Taki and Koster are on PST
Kaz: btw, we need to use PDT and EDT, though the time itself is correct
McCool: right
Lagally: let's discuss lifecycle together for TFs
McCool: ok
Lagally: maybe we could move Scripting session?
McCool: let me talk with Zoltan
Lagally: Profile discussion to be 1h
McCool: possible new slot on
Thursday
... why don't you post your conflict to the Members list
... and discuss the necessary changes
... we can fix the schedule next Wednesday
Lagally: takeaway from the virtual
meeting should include use cases to identify gaps
... btw, the current time for call 1 seems to be too early for
some of the European attendees
... so sent a message on a Doodle poll to see possible new
slots
... let's see the results
Kaz: please note that next week
US Daylight Saving Time will start
... so making the call one hour later would be the same time
for Japan, Singapore, etc.
Lagally: it's confusing within the
upcoming a few weeks
... let's see the Doodle poll results first
Lagally: talked about use cases
... related to media streaming
... voice interaction is another example
... talked about several media companies as possible
stakeholders to be contacted
McCool: talking with David Ezell
about retail use cases
... media interaction to be included there as well
... interactive media and media control
... some of the media-related companies are also interested
Lagally: device control and media handling for home network use cases as well
McCool: need for control media
playback
... and orchestration within home network
Lagally: Chris Needham has volunteered
to contact some of the stakeholders
... would like to contact NHK as well
... that was the discussion from call 1
Lagally: need to ask Toumura-san to regenerate the SVG
McCool: yes
Lagally: would like to merge PR 449 itself
McCool: ok
Lagally: merged
Lagally: Govtech use case to be done next week with the Singapore guys
Lagally: retail use case also to be discussed with David Ezell
McCool: OK with merging PR 448 but need to review PR 447
Lagally: let's review it quickly then
Lagally: (goes through the changes)
McCool: not mentioned here is edge
computing
... variant is including AI in the workflow
... much interest there
Lagally: ok
... why don't we merge this PR itself, and you can create an
additional PR for that
McCool: ok
Lagally: merged
Lagally: cross-protocol
interworking
... would like to keep it open for further discussion on
profile during the virtual f2f
... cross-protocol interoperability should be considered
... would suggest we keep it open
Lagally: comment on use case description
McCool: let's say we agree that we should have more structured/detailed use case description, and we're working on that
Kaz: agree
... and we can mention the use case repo URL as well
McCool: yeah
Lagally: (updates the comment on Issue 446)
Lagally: the other issues are also
identified with labels
... most of them have stakeholders and owners
McCool: we can make up something
about discovery use cases
... should have some more brainstorming, and then would
generate some use case description on the discovery repo
McCool: we could generate some use case on data streaming based on the need from Singapore and ME guys
Lagally: need concrete owners who would generate use case descriptions
Kaz: regarding Singapore Govtech
and NHK, I think we should help them generate initial use case
descriptions
... and then ask them to help us improve them
McCool: exactly
... would make sense?
Lagally: ok
... anything else for today?
(none)
