Agenda review
Sebastian: any other agenda?
(none)
Guests
Sebastian: guests from Fraunhofer to present
Kaz: welcome Carlos Velasco from Fraunhofer
Shreekantha: also from Fraunhofer
Sebastian: and another guest, Josh Cohen
Josh: worked at Microsoft on SOAP standards
... like interoperable things and developing a passion for
smart homes
... interested in IETF group also and can work on prototypes
and code
<joshco> ya, also in DMTF.org main author and chair of
WS-Management, which is now ISO/JTC1,
<joshco> ok i viewed the IP webpage, is there a clickthrough
form I'm supposed to fill out for it?
<joshco> I understand it! thanks I hereby offer a non-exclusive
royalty free license to any silly and uninformed things i say
McCool: there is plenty of development work to be done
Josh: curious about the REST architecture aspect
McCool: please review the reference implementation
Sebastian: now welcome Fraunhofer to present
Frauhofer's talk about LinkSmart Thing Directory
Farshid: presenting and introduce the Fraunhofer colleagues
... Fraunhofer is a collection of institutes with a 2.8B
research budget
... the present department is User Standard Computing
... focus on IoT, Industrie4.0
... building reusable components for IoT as enablers to build
larger systems
... have used Linksmart in projects in 10 countries
... based on senML standard
... sensorThings API supported
... current project is creating a system for monitoring
buildings
<McCool> McCool: preview of my comment: energy-efficiency
use-case should be captured using our template as a WoT
use-case
Farshid: collecting sensor measurements from gateways and
provide metadata
... Thing Description is used to package the metadata
<McCool> McCool: another comment: mention discovery TF, DIDs
Farshid: TD exposes endpoints for history
... using Thing Directory and decided to implement their own
directory
<McCool> McCool: also, meta-data block is interesting; to
discuss in use-case
Farshid: Linksmart Thing Directory in golang
... all open source and public
... description of internal architecture
... consisting of a catalog, schema loader, validator, internal
model, controller...
... http based RESTful API but other APIs may be used due to a
pluggable architecture
<McCool> McCool: I also want to mention edgeX integration...
might be useful to use the linksmart component there
<McCool> McCool: ttl is optional... to discuss
Farshid: design decisions include a loadable schema
<McCool> McCool: open issues are how to handle validation when
there are semantic extensions being used
<McCool> McCool: is there a way to notify consumers of changes
to TDs?
<McCool> McCool: is there a search mechanism, eg via keywords,
template, etc? does pagination returns tds or td ids?
Farshid: API with query and path-fetch endpopints
<McCool> McCool: partial TD issues; are returned values always
valid TDs?
Farshid: working on documentation and extensions to TD, expect
to be done by end of next month
... questions?
McCool: questions on the IRC
... we have a discovery TF we should discuss, the work seems
well aligned
... looking at DID to replace the UID
... should capture the energy use case in our use cases
... metadata in TD is interesting to discuss, whether the link
construct could be used
... also thinking about edgeX integration
... targeting deployment in October
... ttl should be mandatory for most use cases
... is there a way to do search?
... are the partial results from TD path requests valid TDs?
... we could follow up later
Sebastian: could Farshid join the next discovery TF meeting to
discuss further?
... also could there be a contribution to the standard?
McCool: consider this to be a potential candidate
Carlos: if Farshid has the bandwidth it is OK to contribute
Sebastian: as a time check, we should move this discussion to
the Discovery TF
... can we get a copy of the slides?
McCool: email to sebastian and he will post on the GH wiki
Meetings update
Sebastian: singapore govtech next Tuesday 2pm in Europe
... time change for the mktg call; one hour later; mccool will
send out a calendar invite
Kaz: already sent out updated webex coordinate to the group
list and updated the marketing wiki
McCool: update on POC for event in October
Sebastian: On April 9 the TD and Architecture documents were
published as official W3C Recommendations
... there is also a W3C Press Release and responses are being
collected
... so far 3 reports have been published
... please help collect any articles and forward to W3C
marketing team
F2F planning
Sebastian: next meeting is in June and will be virtual
... there is a new Wiki page
... please check for the latest information and schedules
... please provide preferred time slots on the doodle poll
... looking for a solution to online plugfest software
... does anyone know of a good VPN solution for physical
endpoints
McCool: will discuss more in the next hour plugfest/test
meeting; need to make sure we capture all of the requirements
Sebastian: please register if you plan to participate
TPAC
Sebastian: planning a parallel physical and virtual meeting;
there is a questionnaire to collect feedback on the options
... setting up a doodle pool for time slot preferences

... also time to identify which joint TF meetings are needed

Sebastian: no scripting or architecture or discovery calls due
to the bank holiday

McCool: how do we support developers?
Sebastian: discussion on explainer video production
... new welcome web page
