It is possible to conver such an RDF representation into JSON-LD with the context. 13:22:15 Victor: ...presenting the RDF version of the TD model... 13:24:25 Victor: the current state of the model is a simple OWL/RDF ontology. Can be extended if needed. 13:25:35 Victor: with OWL2JSON-LD tool it is possible to convert the OWL/RDF ontology to the JSON-LD context 13:26:32 Victor: in this way we can maintain consistency of the TD model (in cases of changes of the mode) 13:27:58 Sebastian: we can use the ontology, and the context in further work as presented by Victor 13:28:38 Dave: concerns about "stability" property 13:28:41 joerg has joined #wot-td 13:29:02 shell it be a decimal number or something else 13:29:20 We could add some comments as per http://www.w3.org/TR/owl-guide/ 13:31:10 Sebastian: how shell we handle versioning in the TD (e.g., in the development phase)? 13:31:25 Dave: which versioning do you mean? 13:31:47 Do you mean the version of the ontoology for the thing description language or the version of a thing itself? 13:32:09 Sebastian: versioning of the context file (e.g., after each F2F there is a major change) 13:32:31 so that we know later on about which version we are talking about 13:32:47 The guide notes: owl:priorVersion is a standard tag intended to provide hooks for version control systems working with ontologies. 13:33:19 Victor: there is currently the version of the ontology, it is v0.3 13:35:39 Sebastian: let us see the current content of the TD Sample folder on GIT (i.e., exisitng Thing Descriptions, available so far) 13:36:04 topic: "Current Thing Description examples" 13:36:29 link: https://github.com/w3c/wot/tree/master/TF-TD/TD%20Samples 13:37:13 Sebastian: please upload further TDs for plugfest 13:37:14 present+ Louay, Joerg 13:38:14 Sebastian: the folder to upload to: https://github.com/w3c/wot/tree/master/TF-TD/TD%20Samples 13:39:00 Sebastian: are there open question regarding the plugfest 13:39:19 n/question/questions 13:40:30 Dave: there are questions related to logistics, do we need to bring a router etc. - see respective emails from the mailing list 13:41:01 http://www.w3.org/2007/OWL/wiki/Ontology_Versions 13:41:01 Dave: there is a web page concerning these issues. 13:43:11 Sebastian: please add your demo and requirements to the web page 13:45:11 http://www.slideshare.net/badenhughes/change-management-and-versioning-in-ontologies 13:45:38 topic: "Topic proposals for breakout session in Sapporo" 13:45:45 Sebastian: there will be a breakout session at the F2F in Sapporo, any proposal for agenda 13:46:12 Dave: what are the processing models for data? 13:47:10 Dave: see email discussion 13:47:15 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. 13:47:24 extracted from https://lists.w3.org/Archives/Public/public-wot-ig/2015Oct/0005.html 13:49:02 Darko: we should distinguish between requirements for processing messages and data models 13:50:48 Victor: data model can be in JSON-LD (supporting semantics), and messages could be simple in JSON (easy to process) 13:51:45 Michael: the context separates the content and the data model 13:52:42 Dave: metadata could be distinguished, e.g., this related to protocols 13:52:56 We should also discuss communications metadata e.g. what is needed to talk to a given server 13:54:40 Dave: we should have a clear roadmap what we want to produce during the breakout session 13:54:59 ...and later in the WG 13:55:36 Sebastian: shell we define the agenda in advance 13:55:52 Dave: let us use a wiki page to gather propsoals 13:56:00 we need to plan work on an Interest Group Note for thing descriptions 13:56:19 Action: Sebastian to create a wiki page 13:56:19 'Sebastian' is an ambiguous username.
