  Quick Updates / Questions

    Vacation plans

   Cristiano: maybe middle of August

   Zoltan: on vacatation right now

   Mizushima: beginning of September
   … I can even join since it is night time in Japan

    Publication plans

   Daniel: I don't think we are in hurry

   Zoltan: Started work on discovery
   … should converge on discovery first
   … maybe updated note in autumn

   Cristiano: +1
   … collect more substantial changes


    Publish Thing Description schema and Types in another npm package


     [13] https://github.com/w3c/wot-scripting-api/issues/327

   Daniel: Cristiano proposes to split TD and API changes

   Cristiano: Issue related to WebThings io work I am doing
   … versioning scheme is not very clear

   Daniel: add historical changes section

   Zoltan: managed version?
   … version the source

   Cristiano: TD does not publish on NPM

   Cristiano: I can try to work on the split
   … NPM needs to be done by DanieLP

    Should writeProperty() return a value


     [14] https://github.com/w3c/wot-scripting-api/issues/193

   Daniel: interoperability with ECHONET is important here

   Kaz: working on ECHONET binding
   … might take longer

    observeallproperties and unobserveallproperties methods are missing


     [15] https://github.com/w3c/wot-scripting-api/issues/312

   Cristiano: WebThings can get all events
   … in this case binding acts already
   … the need is to capture this situation in scripting
   … difficult to know whether to re-open connection

   Zoltan: can provide convenience API
   … subscribe all events / properties
   … explain exception
   … one can do with one or many requests
   … observeAll present and runtime can decide wheteh to use
   binding or loop

   Cristiano: if binding does not support observeAll we can also
   throw error
   … makes clear what the binding supports

   Zoltan: we could do both.. having option
   … observeAll is like convenience method
   … convenience methods easier to maintain
   … having option "strict" w.r.t. to TD op's

   Cristiano: Wonder whether this is better done in utility
   … we use strict always
   … similar to observeProperty .. binding not supporting

   Zoltan: seems a bit different to me
   … strict way by default but can be relaxed

   Cristiano: should stick to one rule
   … strict to operation

   Zoltan: can add interaction-options in the future if there is

   Daniel: still have binding issue

   Zoltan: miss next Monday
