Victor start the presentation on "JSON-LD Context proposal for Thing Description"

n/start/starts

"Context file proposal for Thing Description instances (Victor Charpenay)"

Victor: a JSON-LD context has been proposed
... the context can be used to write TDs
... an alternative is to create an RDF representation of a TD. It is possible to conver such an RDF representation into JSON-LD with the context.
... ...presenting the RDF version of the TD model...
... the current state of the model is a simple OWL/RDF ontology. Can be extended if needed.
... with OWL2JSON-LD tool it is possible to convert the OWL/RDF ontology to the JSON-LD context
... in this way we can maintain consistency of the TD model (in cases of changes of the mode)

Sebastian: we can use the ontology, and the context in further work as presented by Victor

Dave: concerns about "stability" property

shell it be a decimal number or something else

<dsr> We could add some comments as per http://www.w3.org/TR/owl-guide/

Sebastian: how shell we handle versioning in the TD (e.g., in the development phase)?

Dave: which versioning do you mean?

<dsr> Do you mean the version of the ontoology for the thing description language or the version of a thing itself?

Sebastian: versioning of the context file (e.g., after each F2F there is a major change)

so that we know later on about which version we are talking about

<dsr> The guide notes: owl:priorVersion is a standard tag intended to provide hooks for version control systems working with ontologies.

Victor: there is currently the version of the ontology, it is v0.3

Sebastian: let us see the current content of the TD Sample folder on GIT (i.e., exisitng Thing Descriptions, available so far)

"Current Thing Description examples"

<dsr> link: https://github.com/w3c/wot/tree/master/TF-TD/TD%20Samples

Sebastian: please upload further TDs for plugfest
... the folder to upload to: https://github.com/w3c/wot/tree/master/TF-TD/TD%20Samples
... are there open question regarding the plugfest

n/question/questions

Dave: there are questions related to logistics, do we need to bring a router etc. - see respective emails from the mailing list

<michael> http://www.w3.org/2007/OWL/wiki/Ontology_Versions

Dave: there is a web page concerning these issues.

Sebastian: please add your demo and requirements to the web page

"Topic proposals for breakout session in Sapporo"

Sebastian: there will be a breakout session at the F2F in Sapporo, any proposal for agenda

Dave: what are the processing models for data?
... see email discussion

<dsr> One way this impacts the data model serialisation is whether it is necessary to process the models into a set of RDF triples and operate on those, or whether this can be avoided through direct access to a hierarchical data model.

<dsr> extracted from https://lists.w3.org/Archives/Public/public-wot-ig/2015Oct/0005.html

<dsr> Darko: we should distinguish between requirements for processing messages and data models

Victor: data model can be in JSON-LD (supporting semantics), and messages could be simple in JSON (easy to process)

Michael: the context separates the content and the data model

Dave: metadata could be distinguished, e.g., this related to protocols

<dsr> We should also discuss communications metadata e.g. what is needed to talk to a given server

Dave: we should have a clear roadmap what we want to produce during the breakout session
... and later in the WG

Sebastian: shell we define the agenda in advance

Dave: let us use a wiki page to gather propsoals

<dsr> we need to plan work on an Interest Group Note for thing descriptions
