Today we will review the charter and roadmap 15:11:04 Later on we can talk about how to organise the work 15:11:18 charter: https://github.com/w3c/wot/blob/master/TF-LD_charter.md 15:11:47 rrsagent, draft minutes 15:11:47 I have made the request to generate http://www.w3.org/2017/03/03-wot-minutes.html kaz2 15:13:43 achille_zappa has joined #wot 15:15:26 dsr presents the current proposal for TF-LD charter and the motivation for the TF 15:15:30 rrsagent, make log public 15:15:35 rrsagent, draft minutes 15:15:35 I have made the request to generate http://www.w3.org/2017/03/03-wot-minutes.html kaz2 15:17:08 present+ Achille 15:18:34 Darko asks for comments in respect to the aims and charter 15:19:05 mariapoveda has joined #wot 15:19:11 Mark_Wharton has joined #wot 15:20:31 Peter: I am from Iotics Labs which is aligned with the ideas of the web of things. We see semantic interoperability as really valuable, and we want to see what’s possible. We support a bottom up approach. 15:21:15 Say I want an ontology for farm tractors, what should I do? What corresponds to best practices? 15:21:35 q+ 15:21:58 q? 15:22:41 Mark: I also am from Iotic labs. We’re new to W3C. Are people aware of the NSF’s work on units of measure? 15:23:08 Dave: yes, and likewise for a range of groups, e.g. QUDT 15:23:28 I'm from the Ontological Engineering Group and we are involved in VICINITY, an European project in which we plan to develop several ontologies, one of them for WoT. So I think the TF can benefit from our experience with semantics and linked data and we will benefit of being align with your model 15:23:46 Zakim has joined #wot 15:23:55 [present: Kaz, Dave, Achille, Aprna, Darko, Maria, Mark, Peter, Victor] 15:24:12 s/Aprna/Aparna 15:24:40 pwhale has joined #wot 15:25:22 Maria: We’re a resesearch group at a university in Madrid and working on semantic technologies and we’ve been working on ontologies for some while now, and we want to contribute our experience. 15:26:00 Darko: that’s great 15:27:14 Achiile: I am from the Insight Centre in Ireland, We have done a lot of work on the Semantic Web and are involved in related EU projects, e.g. BigIoT. 15:28:11 s/Achiile/Achille 15:28:27 Victor: I am working at Siemens on the Semantic Web and the Web of things 15:29:31 I’ve worked on using JSON-LD for thing descriptions, and joined this task force with an interest in the role of semantic domain models. 15:30:21 Darko: I work with Victor at Siemens, and have been working with semantics for a while, and for the web of things. 15:32:21 We have yet to exploit semantic modelling for the IoT in a big way, and I believe that W3C is a good place to start this work. We work on defining some vocabularies and have a few slides to show later 15:33:11 Aparna: I too am at Siemens, my main research is on creating semantic models for the web of things and how to support transformations and compositions of services. 15:34:48 Topic: Slide presentation by Darko 15:35:17 Dave asks Darko to send the slides as soon as practical 15:36:52 Darko: I would like to work on use cases & requirements, cross domain vocab for WoT, semantic concepts and demo’s of their benefits, and collaboration and outreach 15:37:56 The use cases and requirements should be limited to those relevant to WoT and semantics 15:38:29 We should survey work in existing activities, e.g. W3C, OCF, oneM2M, and so forth 15:40:04 We should look at existing cross domain vocabularies, and we are expected to lead the work on the WoT ontology (CBP) 15:40:35 We should look at what’s needed to support validation, e.g. how to model constraints 15:41:24 We also need to look at the vocabularies needed for specific IoT platforms 15:41:57 and to look at how to enable interoperability with domain models from other SDOs 15:43:06 We should consider how to provide easy to use tooling for vocabularies 15:44:00 Darko: notes Google’s initiative around iot.schema.org on smart home vocabularies 15:44:47 That is still at a very early stage and we should seek to collaborate with them 15:46:31 Darko: My third point is around semantic concepts for the web of things. 15:47:31 What is needed to support semantic search, validation, inference, etc. How can we demonstrate the benefits of semantic approaches? 15:48:53 How can we support lightweight semantic models that are easy to compose? 15:49:22 Darko uses terms like templates and recipes ... 15:51:10 Darko shows a slide on collaboration between WoT WG, WoT IG and iot.schema.org 15:52:09 We should aim to minimise barriers for interoperability 15:52:55 We can also work on recommendations for best pratices 15:53:10 rrsagent, set logs public 15:55:10 Dave: Michael K is organizing a call for people interested in iot.schema.org next week, and we should ask Michael to present the outcome at our next call. 15:56:17 Darko asks for comments on his presentation. 15:56:44 Dave: I would like us to discuss priorities for the task force 15:58:17 Dark: regarding the first bullet 15:58:26 * Clarifying the Linked Data model for things in terms of use cases and commercial IoT standards 16:01:17 Dave: we need to reach a broad concensus for the existing commercial platforms and devices so that we can provide timely advice to the WoT WG 16:02:44 Darko: I want us to work on demoing the benefits of semantic interoperabilty 16:05:03 Dave: I was proposing to do that along with validation of semantic interoperability 16:05:11 and to do so within 6 months 16:05:34 sorry, I have lo leave like in 5 minutes. Just wanted to say that I'll be happy to work on the ontology (or ontology modules and cross domain concepts) development and documentation. I could also contribute to constraints evaluation but I'm not an expert in SHACL. Anyway I think the vocabulary is the base for the validation. For further tasks like demostrating the benefits I can ask my colleagues 16:05:52 We would need to pick some use cass that demo semanticn discovery and compositions 16:08:07 Dave: I would like people to propose changes to the charter as github issues and we can aim to resolve them in the next call on March 17 16:08:14 same slot as today 16:08:38 Dark thanks everyone and looks forward to talking again in two weeks time 16:08:50 tx dsr! 16:09:34 rrsagent, make minutes 16:09:34 I have made the request to generate http://www.w3.org/2017/03/03-wot-minutes.html dsr 16:16:00 Max has joined #wot 17:30:41 Zakim has left #wot
