So will create that Team on GitHub. 14:18:26 victor: updated current practices document 14:18:43 victor: working on exposing SSN information as wot things 14:19:15 darko: what do we want to demonstrate at the plugfest? 14:20:14 danh: do we want to do semantic alignment and mapping? 14:21:15 darko: we are just at the beginning and should start with something simple 14:21:18 Karen has joined #wot 14:21:29 darko: work toward a common set of terms 14:21:57 darko: so everyone can discover and integrate using common terms 14:22:39 dsr: even for simple scenarios there is a need for context, at least location to start with 14:22:48 q? 14:22:52 ack kaz 14:22:59 q+ 14:23:22 darko: shall we define some scenarios and specific need for additional common vocabulary? 14:23:38 dsr: yes, that's the general idea 14:24:09 dsr: but be careful what we are trying to standardize vs. what we need to define for plugfest 14:24:27 ack dan 14:24:59 danh: work from concrete scenarios and what is available 14:25:20 q- 14:25:26 victor: has an outstanding PR with some of these concepts 14:25:56 danh: start with scenarios, then build recipes etc on top of that 14:26:30 victor: share screen with the PR material 14:27:26 q? 14:27:56 -> https://github.com/w3c/wot/pull/331 Pull Request 331 by Victor 14:27:59 victor: same table as shown in TD meeting, PR #331 14:29:20 victor: integrates many vocabularies including geospatial, etc. 14:29:53 q? 14:31:04 darko: need scenarios to be described, how to motivate people to implement the annotation 14:31:24 victor: the intention is that participants will annotate their TDs 14:32:07 present+ Dave_Raggett 14:32:27 ack k 14:32:32 kaz: how can we collaborate with TD and consolidate the discussion, can we have a joint call before the F2F? 14:33:45 mjkoster: need a follow-on discussion on the semantic annotation 14:33:56 topic: semantic processing 14:33:57 rrsagent, make log public 14:34:01 rrsagent, draft minutes 14:34:01 I have made the request to generate http://www.w3.org/2017/06/23-wot-minutes.html kaz 14:34:23 danh: bring up PR on screen 14:34:42 Meeting: WoT IG - TF-LD 14:35:21 rrsagent, draft minutes 14:35:21 I have made the request to generate http://www.w3.org/2017/06/23-wot-minutes.html kaz 14:37:25 danh: enable discovery using terms from different vocabularies 14:37:38 danh: based on a semantic bridge 14:37:56 danh: ontology to consolidate other ontologies 14:39:20 dsr: decoupled ontology development is more scalable, and can be harmonized using intermediary concepts in a bridging ontology 14:39:31 danh: like an integration context? 14:39:48 dsr: provide common concepts across ontologies 14:40:11 dsr: can't always map directly 14:40:50 danh: there are some different techniques for bridging 14:41:03 q+ 14:41:22 dsr: looking at existing work e.g. inter-iot (reference?) 14:41:48 dang: maybe going different directions but targeting the same result 14:41:56 s/dang/danh 14:43:06 danh: using sub-class mapping rules developed for domain-specific models 14:44:21 dsr: a bridging ontology can be used for discovery, for adaptation there may be more logic involved e.g. translation 14:45:55 dsr: use concrete concepts like temperature, etc. 14:46:30 mapping may depend on the context, e.g. the data and metadata 14:46:32 danh: use common scenarios 14:46:45 q? 14:48:45 Inter-IoT http://www.inter-iot-project.eu/ have done a lot of work on mapping between IoT ontologies 14:49:14 They say: NTER-IoT aim is to design, implement and test a framework that will allow 14:49:14 interoperability among different Internet of Things (IoT) platforms. 14:49:35 victor: tools question? 14:49:35 q? 14:50:24 I was asking about using the HyLAR JS reasoner (https://www.npmjs.com/package/hylar) 14:50:38 kaz: do we want to work with automatic ontology conversion? 14:51:56 danh: they don't try to convert ontologies but use rules for mapping 14:52:28 kaz: similar to the topic of binding template 14:52:57 danh: should use logic and reasoner to do the job at scale 14:53:37 kaz: matthias is proposing a separate protocol binding topic we can discuss on the next Wednesday call 14:53:43 ack k 14:54:59 danh: can demonstrate step by step process that makes it easier to understand 14:55:41 darko: third topic, recipes 14:56:38 darko: example of a recipe to turn on a light when motion is detected in a room 14:56:54 Recipe: https://github.com/wot/blob/master/linked-data/thing-description-recipes.md 14:57:01 i/third topic/topic: Thing Description Recipes/ 14:57:04 darko: json-ld example 14:57:14 https://github.com/wot/tree/master/linked-data/contributions/thing-description-recipes 14:58:00 darko: please review and comment 14:58:13 q+ 15:00:32 darko: defines the recipe for orchestrating the interaction capabilities of multiple devices 15:00:48 using iot.schema.org capabilities 15:01:29 maria: are the semantics included in the recipe or imported? 15:02:13 darko: the semantic annotation is included in the recipe, and is used to discover and configure 15:02:45 darko: comments? 15:03:42 dsr: this brings up the question of semantic composition vs. syntactic composition of interfaces? 15:05:18 darko: please contribute to these activities and review/comment 15:05:37 danh: will we still try to converge by the plugfest? 15:05:56 darko: yes, we hope to start the process of convergence 15:06:11 q+ 15:06:16 ack M 15:06:17 darko: we need to drive toward involving all the participants 15:07:16 darko: time is short but we can make some demonstrations and a simple scenario with the motion sensor + light, temperature sensor + air conditioner 15:07:46 darko: follow up over email, no more telcos until F2F 15:08:06 darko: adjourn and thanks 15:08:29 [ adjourned ] 15:09:11 rrsagent, draft minutes 15:09:11 I have made the request to generate http://www.w3.org/2017/06/23-wot-minutes.html kaz 15:20:46 elena has joined #wot 15:23:53 zkis has joined #wot 15:49:32 dsr has joined #wot 16:01:28 Karen has joined #wot 16:07:33 zkis has joined #wot 17:05:50 dsr has joined #wot 17:20:41 Karen has joined #wot 17:35:14 Zakim has left #wot 17:38:28 Karen has joined #wot 18:22:29 Karen has joined #wot 18:44:15 Karen has joined #wot
