... Preparation for the next F2F meeting and the Plug Fest participation
... Proposal for aligning semantic models from W3C WoT TD, OCF, oneM2M etc.
... any topics for the next f2f meeting?
danh: roadmap?
darko: tried to start
something
... ideas on the roadmap
... didn't manage to provide any concrete proposal yet,
though
... one question to Maria
... do you want to talk about your ontology work?
... temperature sensor, etc., during the breakouts
maria: can talk about
something
... let me look for the slides
darko: ok
... btw, is Michael McCool around today?
... no...
... recently, we talked about linked data model for WoT
apps
... we'd like to think about practical alignment with the
model
... devices coming from different areas
... WoT, OCF, oneM2M, ...
danh: Darko's IRC disconnected?
darko: share his screen
again
... [The Linked Data for WoT Applications (persons?)]
... there is interest in starting work alignment with
ontology/semantic models
... different levels
... 1st level (interactive model): WoT TD and OCF, etc.
... 2nd level (horizontal vocabulary): SSN/SOSA, SAREF
(oneM2M), Haystack, Echonet
... demo during plugfest
... discover devices regardliess of the ecosystem
... interaction between devices from different ecosystems
... aligning with existing ontologies
... TD ontology derived from Maria
... also McCool's work
... OCF model
... and also oneM2M model
... on our Siemens side, we also started the 2nd level
alignment
... any comments?
danh: kind of confused
... alignment for what purpose?
... present information?
... get JSON-LD?
darko: what is the goal?
... we have big 3 kinds of models
... WoT TD, OCF and oneM2M
... the first call is provided by some interaction model
danh: so the goal is discovery?
darko: yeah
... the next level is putting the W3C devices and other devices
work together
... regarding scripting api tf, Michael Koster is working on
OCF side
... the first part should be achieved by us
... e.g., I'm looking for a device regardless of what the
device belongs to (ocf, oneM2M, ...)
<achille_zappa> align = map ?
darko: need to discover devices which (potentially) belong to various standards/ecosystems
danh: ok
kaz: the point here is
... starting with interaction model as the 1st level
... and handling concrete ecosystem-based vocabs as the 2nd
level
... right?
darko: right
... any volunteers for this work?
danh: can work on SOSA
darko: Victor also has started
some work
... anyone who would work on the interaction model?
... e.g., based on the OCF model
maria: not familiar with OCF
model itself
... my contribution would be more related to oneM2M
darko: ok
... my impression is that McCool would also appreciate your
help
... let's see
... handling RDF
... [Thing Description Recipes (Darko)]
... interop client creates a WoT app based on some recipe
... that is a kind of template
... capability template
... discover first, instantiate, ...
... there two tasks
... recipe format based on TD and capability templates
... and then implement a prototype
... the focus would be TD
... not mixing with another standard
... would like to volunteer myself for this
... anybody interested in addition myself?
koster: would like to work on
it
... how smart things work
... machine constructive and human beings
darko: formalizing
capabilities
... let's see what we can do
danh: me as well
... interested in semantic mashup for web services
... template for SPARQL recipe
darko: ok
... could be incorporated with semantic web services
... need automatic query things
koster: can you go back to the previous slide?
darko: [The Linked Data for WoT
Applications (persons?)]
... orchestration of multiple devices
darke: make sense
... two devices from different ecosystems
... also interaction of devices from only WoT
... is possible
... [Semantic Processing for Web of Things]
... not finished this slide yet
... problem statement for semantic processing
... validation and verification
... specify property, event, action
... then you can validate the value, e.g., within specific
value range
... your property is of some certain type
... are all the possible types within your TD semantically
correct?
... some possible semantic constraints
... this is also some sort of task
... Victor working on validator
... Maria also expressed some interest
danh: semantic processing here is
just validation/verification?
... low level of semantic
darko: this is based on the
discussion so far
... it's up to us to decide what should be done for semantic
processing
... first version of the validator could be a starting
point
danh: there are several things in
"semantic processing"
... RDF semantics, etc.
... data type checking for RDF nodes
... taxinomy classification, etc.
... checking is available within programming languages
already
darko: do you have interest in this topic?
danh: yeah
... but we should clarify the purpose of semantic
processing
... in addition to vocabulary alignment
darko: ok
... my intention is raising topics first
... and get people interested
... would contact all of you who are interested in each
topic
... during upcoming telcos, we can talk about the details
mccool: (joining now)
... for what do you want to get volunteers?
darko: (goes through the topics)
mccool: certainly interested in
OCF things
... aligning the OCF model with the W3C WoT model
danh: can moderate the last one
(Semantic Processing)
... would like to talk with Victor, etc., as well
... SSN is still on its way for REC
darko: TD Recipe: Koster, Danh,
Darko
... Semantic Processing: Danh, Victor, Maria
maria: interested in semantic
validation
... but not sure what this topic itself means here
... happy to follow the discussion but a bit confused
darko: this slide is rather
empty, so we'd work on the details from now on
... we're getting out of time
... Maria's presentation for the next call
danh: also can give some talk
(10min or so, etc.)
... during the next call
darko: ok
... will contact you offline
... any other business for today?
mccool: are those slides available anywhere?
darko: will send them
... in two weeks we'll have the next call
