  review of last week's notes

   <kaz> [7]Feb-10

   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)

   on.md

     [12] https://github.com/w3c/wot-testing/tree/main/events/2021.03.Online/scenarios/geolocation.md

   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
