McCool: please use the main branch going forward as targets for
your PRs
… any objections?
… none - (meetings are approved.)
Agenda
- getting Wiki organzied
- updating TDs
Planning
McCool: we added the hardware.md file to the repo, this will be
input into profiles
… development size vs. minimum size
… ESP32 and Nordic were discussed, Nordic has 32 kb
… There's a 1000:1 ratio between large and small
Lagally: why not create a list of plugfest devices
McCool: we can create a list of implementation platforms where
plugfest participants describe the hardware they use and
capabilities they support.

McCool: we have an initial list, need to fill in details

Daniel: there are several different versions of the Siemens
IOT-2020
Koster: platforms are pretty much capturer if we consider
Nordic, ESP32, Raspi, ESP-8266
Daniel: Sebastian was doing some work with node-MCUs and LUA
Philipp: embedded radio consumes a lot of resources
McCool: topic: TDs
McCool: we need to gather TDs, I plan to look into geospatial
examples
Kaz: perhaps some new devices from Japanese community group?
Toumura: (can't hear what Toumura-san mentioned due to some
audio trouble)
Mizushima: Japanese CG would like to contribute on the new TD,
would like to talk with Toumura
Kaz: there was some audio problems with Toumura-san's line, but
a potential contribution on a Raspberry Pi could be likely
considered
McCool: I know Matsukura-san was very interested in greenhouse
horticulture
… we can break up the readme and create a dedicated scenario
description in a separate file.

Philipp: I'm working on a dev kit to make development simpler
… when this is ready, I'm happy to provide some devices
McCool: is this Nordic based?
Philipp: yes
McCool: In addition to hardware we need software stacks with
certain capabilities
Philipp: it will contain the full RIOT SW stack
McCool: We also have goals, each group could use their own
McCool: we discussed signing requirements and corresponding use
case in the security TF
… perhaps RIOT OS can work on that?
… controller consumes a TD for controlling a device
Philipp: This is kind of complex and we don't have security
implemented yet
McCool: Security is optional, this would be an interesting
real-world use case
… we could use nosec for the test case
… also on a small device I cannot do RDF etc.
… if I do mDNS discovery I can get hundreds of devices
… we should be able to use filters
… this raises a requirement to have filters even for self
discovery
McCool: People are encouraged to contribute their own scenarios
… we should add geolocation mashup (creates scenario
description file)

Daniel: It was difficult to get TDs from github
… I used a map service to lookup location information
McCool: other use cases?
Koster: I'm working on a "one fieldbus" project,
… putting together a small reference platform, perhaps also add
a scenario
Koster: not sure if I have sth. available for plug fest
McCool: I have not seen any OPC-UA binding, Siemens had their
Pump device
… we need to get TDs updated
<Zakim> dape, you wanted to ThingModel scenaril
Daniel: Getting from a thing model to an actual TD is a
scenario
Koster: I'm also working on sth similar in SDF
McCool: thing models / digital twins need a scenario too
… instantiate a TD from a TM
Koster: I have a modbus power supply I can put on a bridge and
create a TD
McCool: we only have two weeks left, please write down concrete
scenarios
… probably some university work on agricultural scenarios can
be considered
… need to discuss with Fraunhofer about discovery
Kaz: Do we use VPN with Amazon web services?
McCool: not necessarily, discovery with mDNS over the Internet
is difficult
Kaz: we need to involve Farshid as well
McCool: will discuss discovery scenarios with Farshid on Monday
… AOB?
none
