14:13:56 RRSAgent has joined #wot 14:13:56 logging to http://www.w3.org/2017/03/17-wot-irc 14:14:01 Zakim has joined #wot 14:15:28 present: Dave, Darko, Aparna, Maria, Michaek, Uday 14:15:36 chair: Darko 14:15:44 scribe: Dave 14:16:10 Charter: https://github.com/w3c/wot/blob/master/TF-LD_charter.md 14:16:35 Darko runs through the agenda for today 14:16:38 agenda: https://www.w3.org/WoT/IG/wiki/IG_Linked_Data_and_Semantic_Processing_WebConf 14:17:33 Topic: Finalize the charter 14:18:20 Darko: I see two streams of work 14:19:25 He displays the github issues 14:19:56 Victor's comment: https://github.com/w3c/wot/issues/306 14:20:18 https://github.com/w3c/wot/issues/309 14:20:26 https://github.com/w3c/wot/issues/306 14:20:35 aparna has joined #wot 14:26:14 We discuss the issue that Victor raised around validation vs inference. 14:27:06 Dave: we need both, e.g. to validate thing descriptions involving semantic constraints involving inference down class - super class chains 14:29:46 Victor is away this week, but will be back next week. 14:30:16 Dave agrees to look at proposing some changes of wording for discussion with Victor 14:30:34 Darko: let’s now look at use cases, what do we need? 14:30:57 Dave: we need use cases to ground what we’re doing when talking to others 14:31:47 Michael: we can be informal, and simply explain the use case in regular text, bullet points etc. We don’t need to get formal 14:32:33 Dave: we may be able to leverage the use cases being worked on by the Joint White Paper activity by Paul Murdock\ 14:33:06 Darko talks about his ideas for “recipes” for re-usable templates. 14:35:12 Dave: I think we need to clarify the terminology as it sounds very similar to what I’ve described in respect to syntactic and semantic modularity 14:36:57 Michael: RDF triples are like IETF link types, I am not totally clear about the differences between sub-classes and types 14:37:16 The edges of the graphs are important 14:38:18 The IETF work is looking at dynamic linking, e.g. how does the thing’s behavior vary over time 14:38:45 Recipes include dynamic processes 14:39:08 We need semantics for actions 14:39:46 Darko: we need to bring this back to the need to finalise the charter 14:40:07 in RDF subclassOf is a predicate between two classes and rdf:type is stated between an individual an a Class to declare that the individual belongs to that class that is if of that type 14:40:38 (indeed) 14:41:07 Dave: we need to ground reciples and temporal constraints to use cases 14:41:19 s/reciples/recipes/ 14:42:37 Darko: this is relevant to the web 14:44:01 Dave: there are a variety of techniques, e.g. actors, conductors, preconditions and postconditions and so forth. Without use cases to ground the discussion, we risk being arbitrary in what we do and decide 14:44:05 Dark: I agree 14:44:13 s/Dark/Darko/ 14:44:53 Michael: interoperability depends on recipes and using the same terms for the same concepts 14:45:58 What guidance can we offer to iot.schema.org and community groups for particular vocabularies 14:46:38 Darko: we need to enable developers to express the context 14:47:30 Michael: how do thing descriptions link to semantics … 14:49:53 Dave: let’s pick a few use cases to build a shared understanding in this group 14:50:31 Darko: Michael do you want to write an issue in respect to the charter? 14:51:16 Michael volunteers to write a couple of sentences explaining his ideas 14:51:54 We need to make it easy to construct thing descriptions from components 14:53:05 Darko: we’re running out of time, so I propose we don’t resolve on the charter today 14:54:01 Darko: shall we continue using the public IG list? 14:56:33 Dave: yes, this is an IG task force, so we should work in public as there are no patent policy issues 14:57:11 Darko: what about github ? 14:57:53 Dave: let’s follow the way the other task forces are organizing. Kaz should be able to help. 14:58:35 Michael gives a brief status report for iot.schema.org More details in the next call. 14:58:42 rrsagent, make minutes 14:58:42 I have made the request to generate http://www.w3.org/2017/03/17-wot-minutes.html dsr 14:58:49 rrsagent set logs public 14:58:58 rrsagent, set logs public 14:59:07 rrsagent, make minutes 14:59:07 I have made the request to generate http://www.w3.org/2017/03/17-wot-minutes.html dsr 15:04:21 Michael: recipe's ingredients should come from iot.schema.org 15:04:55 peter_whale has joined #wot 15:06:54 please add issues at: https://github.com/w3c/wot/issues 15:09:00 MariaPoveda: we should ask Fernando to talk about his demo, including TD, WoT ontology etc. 15:11:13 rrsagent, create minutes 15:11:13 I have made the request to generate http://www.w3.org/2017/03/17-wot-minutes.html DarkoAnicic 15:12:05 present+ aparna 15:12:22 present+ benfrancis 15:12:43 present+ chrysn 15:12:55 present+ hyojin 15:12:59 present+ jet 15:13:03 present+ Karen 15:13:22 present+ KjetilK 15:13:30 present+ mjkoster 15:13:40 present+ peter_whale 15:13:45 present+ tobie 15:13:55 present+ zkis 15:14:25 rrsagent, create minutes 15:14:25 I have made the request to generate http://www.w3.org/2017/03/17-wot-minutes.html DarkoAnicic 15:15:21 present+ wseltzer_off 15:15:34 present+ ms7821 15:15:59 rrsagent, create minutes 15:15:59 I have made the request to generate http://www.w3.org/2017/03/17-wot-minutes.html DarkoAnicic 17:48:36 Zakim has left #wot 19:37:10 dsr has joined #wot 19:55:41 ahaller2 has joined #wot 22:04:17 ahaller2 has joined #wot 23:48:30 ahaller2 has joined #wot
