Sebastian: good to meet with JSON-LD WG
<kaz> [18]Issues related to JSON-LD
[18] https://github.com/w3c/wot-thing-description/labels/JSON-LD 1.1
got response from the JSON-LD group that they are open for a
joint meeting
ask Kaz to setup a doodle poll for find a good time slot for
the joint meeting
<scribe> ACTION: Kaz will setup a doodle poll for JSON-LD
shall we meet other groups?
Kaz: how about LBD Group?
Sebastian: we can possibly invite them to our usual calls or
could invite them to TPAC too
Kaz: the agenda for TPAC already quite full
Maybe we should invite them after TPAC
Daniel: there is also Spatial Data on the Web IG
are the active?
Kaz: yes
<dape> [19]https://www.w3.org/2017/sdwig/
[19] https://www.w3.org/2017/sdwig/
is this the group that defined SSN?
Daniel: yes
Kaz: to be strict, the SSN spec was generated by the former WG,
and now they're working on the SSN best practices
... note their charter gets expiered end of Sept, need to get
extended
<kaz> [20]Spatial Data on the Web IG Charter
[20] https://www.w3.org/2017/sdwig/charter.html
Collect topics for the vf2f
so far: dynamic TD, Thing Model, component approach for TD
Ege: I like to talk about the System Description
System Description provides opportunity to define the order and
logic which action as example has to executed
Ege: there are simple and complex versions
Kaz: is this similar to SCXML which handles state transition
with time synchronization?
<inserted> [21]SCXML standard
[21] https://www.w3.org/TR/scxml/
Ege: is quite similar to SCXML, but the System Description can
provide more dependencies
<Ege> [22]https://ieeexplore.ieee.org/abstract/document/9191677
[22] https://ieeexplore.ieee.org/abstract/document/9191677
Ege: similar what Victor has presented
<Ege> [23]https://ieeexplore.ieee.org/abstract/document/8524065
[23] https://ieeexplore.ieee.org/abstract/document/8524065
<Ege> For the second one, the publicly available pdf:
[24]http://egekorkan.com/assets/pdfs/2018-FDL-SequentialBehavio
ralModelingforScalableIoTDevicesandSystems.pdf
[24] http://egekorkan.com/assets/pdfs/2018-FDL-SequentialBehavioralModelingforScalableIoTDevicesandSystems.pdf
are there more topics?
lets talk this again next week
PR checks
[25]PR 951
[25] https://github.com/w3c/wot-thing-description/pull/951
PR cannot merged since McCool should check the changes
[26]PR 914
[26] https://github.com/w3c/wot-thing-description/pull/914
is merged
<kaz> [27]PR 924
[27] https://github.com/w3c/wot-thing-description/pull/924
<inserted> scribenick: kaz
Sebastian: would like to wait a bit and ask Victor to see the
possible impacts
[28]PR 937
[28] https://github.com/w3c/wot-thing-description/pull/937
<McCool> (note: I will join second half of TD call, and I hope
we can look again at the oauth-flow PR)
(Victor joins)
PR 937 revisited
[29]PR 937
[29] https://github.com/w3c/wot-thing-description/pull/937
[30]Issue 915
[30] https://github.com/w3c/wot-thing-description/issues/915
Victor: will add necessary updates directly to the branch of PR
937
[31]PR 945
[31] https://github.com/w3c/wot-thing-description/pull/945
Sebastian: mentions PR 945 within PR 937
PR 951 revisited
[32]PR 951
[32] https://github.com/w3c/wot-thing-description/pull/951
McCool: OK with merging this PR but probably need some more
updates
Victor: would like McCool to review this PR again...
McCool: can review it but swamped today, so maybe tomorrow
... another related point is OAuth
... index.html has much content on OAuth updates
Victor: think that is the only possible conflict from my
viewpoint
Sebastian: McCool, please review this PR 951 again then
McCool: ok
... if no problem, I myself can merge this PR
Sebastian: ok
... any objections?
(none)
PR 961
[33]PR 961
[33] https://github.com/w3c/wot-thing-description/pull/961
Sebastian: how to handle geolocation metadata?
... adding several resources by this PR
McCool: here you're saying the name itself is defined by
schema.org?
... this example doesn't really capture the need by the use
cases
Victor: might be make sense to think about a Note?
Sebastian: would propose restructuring the sementic annotation
section
McCool: what semantic search good for is the question
... have discussion during the PlugFest calls as well
... collecting use cases and examples is needed
... we need to look into some concrete examples
Kaz: +1
McCool: and then clarify some guidelines
Victor: when would be the upcoming PlugFest?
McCool: during the week of September 28
Sebastian: note that this was originally from Michael Lagally
... for location-based services
... would suggest we wait until the PlugFest is done
McCool: OK with merging this PR itself but need to continue the
discussion
Kaz: also OK with multiple iterations for this point
... so we can merge this PR itself but we need to continue the
discussion based on some concrete examples based on some
concrete use cases
Victor: thought there was some example
Sebastian: would merge this PR 961 itself and add an Editor's
note
Ege: need some example on the interaction level
... also position level
<McCool> +1
Ege: IoT longitude, etc.
Cristiano: +1
... also agree with Michael to have some good use case
<victor> untile I describe the dataset further on the
PlugFest's readme, here is a link to it:
[34]https://www.vcharpenay.link/talks/td-sem-interop.html
[34] https://www.vcharpenay.link/talks/td-sem-interop.html
Sebastian: adding some property to get geolocation information
Kaz: and we should continue the discussion on that kind of
detail based on some concrete use case :)
Sebastian: (summarizes the points within a comment for PR 961)
[35]Sebastian's comment
[35] https://github.com/w3c/wot-thing-description/pull/961#issuecomment-693490745
PR 960
[36]PR 960
[36] https://github.com/w3c/wot-thing-description/pull/961
Daniel: (explains)
... add unsubscribeevent to the default list and notes
Cristiano: added a comment
[37]Cristiano's comment
[37] https://github.com/w3c/wot-thing-description/pull/960/files#r488430572
Cristiano: An implementation might infer that to
unobserveproperty it needs to unsubscribe from
mqtt://wot.example.com/levelevent topic.
... example of MQTT there
Koster: only information needed is location here
Cristiano: yes
Koster: this is sort of simplification
... if you have multiple forms for subscibe, would be more
complicated
... need to see the use cases
Kaz: yeah, we need some concrete use case about that
... might want to have a smarter mechanism to handle system
integration like Ege's mentioned System Description
Daniel: any possible impacts?
... not sure if this is a breaking change
Cristiano: the note it self is ok but need to think about the
detail
Sebastian: should postpone till next week?
Daniel: ok
Cristiano: ok
Remaining security PRs
Sebastian: depending on the rendering PR (951)?
McCool: yes
Sebastian: should postpone till next week then?
McCool: yes
PR 938
[38]PR 938
[38] https://github.com/w3c/wot-thing-description/pull/938
Sebastian: examples are already using this...
... "Thing Template" is used within the TD spec
[39]TD spec
[39] https://www.w3.org/TR/2020/REC-wot-thing-description-20200409/
McCool: have you fixed all the "TD Template" to "TD Model"?
Sebastian: this is the REC version
... and this PR updates all the "TD Template" within the
Editor's draft
... we might want to think about the possibility of making the
"Thing Model" as a separate spec in the long term
McCool: would object at least in short term
... would use the same content type as TD?
Sebastian: not sure at the moment
... what framework would we use?
... it's still unclear
McCool: possibly similar to link type?
Sebastian: would everybody to review this PR 938
... maybe we can make a decision next week
