   Kaz: welcome Carlos Velasco 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

   Sebastian: please register if you plan to participate
TPAC
