Quick Updates

   <scribe> scribenick: dsr

   Matthias congratulates Kaz on his award!

   Kaz: I’ve been working hard to support W3C Member companies and
   was honoured to receive the award

   <barryleiba1> Very nice! Congratulations, Kaz, and well
   deserved. Thanks for all your work.

   <kaz> [13]TTC Award

     [13] https://www.w3.org/blog/news/archives/7098

   Matthias: any other updates?

   Soumya: I chaired a session on the Web of Things during the IoT
   Week in Bilbao

   Some colleague presentations, the session went well!

   Matthias: any major comments?

   Soumya: no, but a growing interest in role of WoT for
   interoperability

   Matthias: we can discuss the comments at the upcoming F2F

   Taki: we’ve received an email from the IIC testing group

   scribenick: kaz

   McCool: generating draft response and talking within the
   co-Chairs team

   Lagally: what kind of topics would be beneficial for the
   collaboration with IIC?

   scribenick: dsr

   McCool: we have several things we want to discuss with the IIC
   ... Some topics include security review, semantic interop and
   test beds
   ... We want to invite the security review well in advance of
   moving to REC, so perhaps September or October?
   ... There’s some overlap in membership between IIC and W3C, but
   not the same people

   Matthias: the PlugFest call follows this call. I want to go
   over the TDs today, perhaps Soumya can give his presentation
   and demo next week?

   Soumya: I need 5 or 10 mins

Prague PlugFest Documentation

   got reports from all the participants in Prague f2f:
   [14]https://github.com/w3c/wot/tree/master/plugfest/2018-prague

Korea F2F/Plugfest Preparation

   <kaz> [15]registration results so far

     [15] https://www.w3.org/2002/09/wbs/1/WoTF2F201806/results

   Matthias: We need to check the plenary and breakout plans
   ... provides a summary. In respect to the WoT Architecture, we
   need to revisit the use cases and tie them to the requirements

   <kaz> [16]Korea f2f agenda

     [16] https://www.w3.org/WoT/IG/wiki/F2F_meeting,_30_June-5_July_2018,_Bundang,_Korea#Plenary_and_Breakouts

   Matthias: We also need to take a further look at the message
   flows.
   ... In respect to thing descriptions, we need to discuss the TD
   model, and the TD lifecycle
   ... Some terms relating to hardware and software versioning
   ... Some questions for how we formalise thing descriptions as
   JSON
   ... e.g. JSON schema, ABNF, etc.
   ... In respect to WoT Binding, we need some discussion on new
   patterns and MQTT

   Koster: I will update the agenda with some more details

   Matthias: please add your changes by the end of this week

   <mlagally> I mentioned that validiating a TD with the
   plugfest.thingweb tool works quite well - this also contains a
   JSON schema of the current TD

   Matthias: For the scripting API we have several topics to
   discuss, including discovery
   ... and semantic annotations
   ... I would put this under rechartering as it isn’t something
   we have current work for

   McCool: I have a raft of security topics to discuss under the
   API banner
   ... Our charter requires us to have security testing plan and I
   want us to discuss some ideas on how to address this
   ... This only needs to be informative and could be in a
   separate document

   Matthias: in respect to WoT testing …

   McCool: I want to talk about wildcards and extensions under
   testing

   Matthias: under liaisons, we could talk about ECHONET and IIC
   ... we need to progress our discussion on rechartering

   McCool: I am getting a lot of requests for use cases in respect
   to rechartering, and we should discuss this in the context of
   different verticals

   Matthias: intel have recommended we look at how WoT can help
   with respect to at least one specific vertical in some detail
   ... Any other topics we need to add to the F2F agenda? [no]

   McCool: a first cut at the PlugFest recap would be valuable

   Matthias: I’ve upgraded node-wot and will merge the changes
   into the master at the Eclipse foundation

   <mkovatsc> node-wot repo:
   [17]https://github.com/eclipse/thingweb.node-wot

     [17] https://github.com/eclipse/thingweb.node-wot

   Matthias: I will notify the mailing list when it is all in
   place. I have a few small changes still to do and hope to
   progress them tomorrow.

   Lagally: it would be good to have a hosted instance that we can
   play around with at the PlugFest

   Koster: I am planning on something like that and possibly some
   simulated devices

   Matthias: we can try out the event source in node-wot
   ... there are many ways to use node-wot, so it is unclear what
   a hosted instance should do

   McCool: some simple simulations of basic devices e.g. lights
   would be nice
   ... along with a parameterised instance generator

   Matthias: it is easy to run node-wot locally for experimenting
   with WoT apps
   ... but the documentation could be improved
   ... Victor is working on the thing directory with a new version
   by the end of this week
   ... I recommend that people start sharing their thing
   descriptions now to give time before the PlugFest to ask
   questions and resolve problems

Editor’s drafts convergence

   Matthias: this is about aligning the various specs, e.g.
   security vocabulary

   Sebastian plans to discuss this in this Friday’s TD call

   Soumya asks about how to handle collections of things

   <mkovatsc> Links to sub-Things:
   [19]https://w3c.github.io/wot-thing-description/#links-serializ
   ation-json

     [19] https://w3c.github.io/wot-thing-description/#links-serialization-json

   Koster: I’ve been looking about how to apply semantic
   descriptions to the GENIVI hierarchy for automotive

   Matthias talks about the use of links to TDs for substructure

   <McCool> mccool: time check...

   Matthias: scripting API document is on hold as Zoltan is away
   until the F2F

   Koster: I will update the binding doc this week

   Matthias asks mjkoster to look into who wants to experiment
   with binding during the PlugFest

   <Zakim> kaz, you wanted to point out this implies potential
   need for "a group of more than one thing as a thing" and to
   encourage editors to summarize the changes from the previous
   drafts

   kaz: I want to point out this implies potential need for "a
   group of more than one thing as a thing" and to encourage
   editors to summarize the changes from the previous drafts

   Matthias: as this is the *Web* of things we need to be able to
   link between things

   scribenick: kaz

   Kaz: yeah. how to handle combination/collection of "Things"
   should be of interest for advanced use cases. we should be able
   to do that using "links", though

   scribenick: dsr

   Koster: collections via links, I have some use cases for that
