Meeting minutes
Minutes
Lagally: (goes through the minutes)
… will follow up Conexxus
McCool: btw, there was some information on industry cases of WoT during the Marketing call
Lagally: minutes approved
McCool: (gives summary)
Lagally: this use case itself is quite simple on smart homes
Kaz: right
… we should handle geofencing, etc., separately from this use case
… and can generate another separate use case about that as a horizontal use case
Lagally: ok
… btw, what's the status on the liaison with OGC?
McCool: talking with Christine
… it seems there is an IEEE WG on geospatial data as well
Kaz: we should have a joint session with them during TPAC
McCool: yeah
… another question is how to manage the geolocation data
… along with time-series data
Kaz: we can start with some basic discussion based on use cases
McCool: yeah
Lagally: for concrete extensions, we should be careful about our Charter
… current Charter or the next one
… e.g., clustering things
McCool: thinking about orchestration
… are we just concern about grouping the status?
… or what do we want to achieve?
Lagally: seems various topics there
… including permission management
McCool: we have things like OAuth now
… but no standard to manage orchestration
… e.g., a visitor visiting my home would like to get connected with the network at my home
Kaz: let's approve the minutes first :)
McCool: yes, the minutes are fine :)
… regarding the next steps, we have several advanced use cases in the pipe
Lagally: so we added "gaps" to the use case template to clarify the gaps
… what was the conclusion about ECHONET use case description itself?
<sebastian> sorry I have to go
Kaz: was quickly skimming it again today with Michael Lagally ;)
Lagally: ok. the minutes themselves are approved
ECHONET use case
(discussion on the "Gaps" section specifically)
[[
controlling multiple devices in an orchestrated manner is dependent on the implementation of a client application in the current WoT specification
]]
McCool: so there is a gap for multi-vendor orchestration
Lagally: what level of orchestration is expected?
… how the ECHONET spec handles orchestration?
Matsuda: ECHONET Lite Web API spec itself doesn't have orchestration capability
Kaz: ECHONET doesn't have multi-vendor/multi-standard orchestration capability, and so they would like to use WoT for that purpose
Matsuda: right. we just wanted to show you that there is a use case which can't be implemented with existing standards
Lagally: what kind of "orchestration" is expected here?
Matsuda: multiple devices which use multiple data models
McCool: "orchestration" here is not just operation
… but also include data
… so need to maintain the data somewhere
… btw, ECHONET Lite Web API spec has the device spec and the device description
… more than one access point may be involved
Kaz: I'm OK with accepting this use case description itself, but we should clarify our expectation for "orchestration"
… based on some concrete scenario, e.g., the conductor work with the pianist, violinist, drummer, etc. :)
McCool: right. and "orchestration" should include "configuration management"
Matsuda: for the moment, we can avoid using the term of "orchestration" within our use case
Kaz: ECHONET is planning to join the Plugfest during TPAC
… so we can think about actual "orchestration" during the Plugfest and its planning
… note that their spec document is written in Japanese
… but the most important definition is done by tables which include English as well as Japanese
… so we can refer to part of their spec document
McCool: right
Lagally: ok
… Matsuda-san, what kind of features for "orchestration" or "grouping" do you want in addition to your own grouping capability?
Matsuda: things like where to store data, how to handle different data from various vendors, etc.
McCool: we could put them on the document
Lagally: can we have some more detailed description about the gaps?
… grouping and sequence of actions?
McCool: note that it would take a few more weeks for them to add requirements description
… since they need to discuss the changes internally
Lagally: ok
McCool: wondering about the schedule
Lagally: let's go for weekly meeting
McCool: will send an updated invite
Kaz: can we move ahead with the ECHONET use case itself?
… can we ask Matsuda-san to generate the HTML description for the use case document?
<mlagally> Proposal: Include ECHONET use case into use cases document
Resolution: Include ECHONET use case into use cases document
AOB
Lagally: wondering about outreach
McCool: could have joint meetings during TPAC

Kaz: fyi, as I mentioned during the Marketing call today, big companies like Takenaka from Japan have started to use WoT as the basis for their IoT systems :)
Lagally: great!
