Matthias needs to catch up with T2T

Michael to talk about Doodle

for Security TF and OCF TF

also want to talk about Osaka F2F, finalize inputs

last meeting we talked briefly about IETF99

talked about interop that goes across device ecosystems

want to start that discussion in T2TRG, probably on Sunday

some overlap with WoT; many of us agreed that it would be useful to propose

T2TRG chairs sent around an invite, WoT but also OCF, OMA, IPSO

but also in July will have another joint meeting

do we want to have joint meeting only with WoT, or have this larger meeting instead?

if more groups, better to have it in Prague, many in T2T would also prefer Prague

6 people definitely want to join T2TRG in Prague

WoT F2F definitely stays in Dusseldorf

but moving the meeting to Prague would require a train, about 11h

mcCool: would be valuable especially if we can get engagement with other standards bodies

Matthias: to tell T2TRG that having meeting in Praque makes sense

may need Friday for travel

Doodles for Security TF and OCF TF

Security TF Doodle: http://doodle.com/poll/uk5myzvevqshfc7d

OCF Liaison TF doodle: http://doodle.com/poll/fyvt578gwkq3kbzv

<mkovatsc> Security people to invite: Thosrten Dahm, Oscar Garcia-Morchon, Steven Rich

McCool: also Sven Schrecker from IIC/McAfee

<mkovatsc> also Olaf Bergmann

other alliances... KNX, Bacnet

should start activity to look at concise descriptions for TD

CBOR, etc. registration for tags needed

do soon, so good number ranges

Can JSON always be converted to CBOR? Yes, but better to register attribute names in advance to avoid having to put strings into data

so we should register tags if we want to get the most benefit

breakout session in Osaka: Sebastian, want to talk about serialization of TD; CBOR is one of the candidates; there are others (EXI)

for semantics, EXI is better at string encoding

but... let's save the discussion for Osaka

we should also start thinking about how to evaluate the alternatives

not just size; we should talk about what we need from the format

Matthias: we need a strategy and a plan here...

Zoltan: CBOR is used by OCF; also has good handling of binary data

McCool: the use of a format by other standards should be one of our criteria

especially on small devices each format needs code space, so...

F2F: registration deadline is past

added access information for restaurant

currently have 36 participants registered

currently have made reservations for 45

so we have room for some more registrants

Notes on F2F content: OpenFog should be 1h; OCF 1.0 to be covered; need breakout session for binding templates

Question: because OCF1.0 candidate draft is now public, the need for handling confidential information as part of the OCF Liaison

Time for OCF overview: 30m + 15m discussions; OpenFog, 1h, including discussion (eg 40m + 20m)_

Matthias: Star Micronics? Kaz entered, ask him
... if you are a remote participant, please enter your contraints, what sessions you want to attend (will repeat on mailing lists)
... want to start testing implementations against each other

In Santa Clara, still only closed demos, only a few interactions could be cross-tested

so for this F2F, will try to make some more progress on cross-device interactions

for each type: actions, events, properties, etc

advice: if you implement, use a framework that allows you to have arbitrary properties, actions, and events

Matthias: to send a reminder on mailing list...

TF reports

TD: today had extra meeting

to try and close some issues... closed several CRs

on Friday, hope to present final model for F2F, next "stable version" for the next few months

regarding Osaka, added some breakout topics; one will be on TD serialization

need also concrete discussion on JSON-Schema and semantic annotation; need a concrete example

that we can use for the next plugfest

cooperate with JSON Schema group

need to also collaborate with Security TF

will have to look again at TD lifecycle

(McCool: noting no-one with security background will be able to attend in person...)

Other topics: scripting API for management

(prev was actually TD; NOW Scripting)

Looking at web IDL specs

still some open topics, but hope to finalize version in next call

pull request.. 21

<zkis> https://github.com/w3c/wot-scripting-api/pull/21

some changes, renamings; need to document

what versions to use for plugfest: Scripting, will be version on next call (do all discussion this week, Monday is freeze)

decision: postpone scripting call to Tuesday, freeze then

Matthias to update the current practices...

McCool: when can we have a version ready for F2F? *should* be by end of next week

next meeting: draft agenda

report-out on OpenIoT

<mkovatsc> Industry Day Event during oneM2M TP#29 (May 24th, Shenzhen)

<mkovatsc> OpenIoT Event (April 26th, Beijing)
