We want to include the NGSI-LD collaboration in the new charter 14:22:51 mm: We need to have a discussion in the larger group about the new charter 14:24:35 Juanjo: Who will take over the NGSI-LD advocacy? 14:24:46 mjk: I will handle that 14:25:23 Topic: Plugfest 14:26:15 mm: The plugfest is taking place in November at the annual W3C TAPC conference in Kobe, Japan 14:26:54 ... We plan to present the outcome of the Plugfest at a conference session 14:28:04 ... We are planning to offer remote connectivity for the Plugfest and there is a remote participation option for TPAC 14:29:42 Juanjo: We have a presentation 14:30:29 mm: We could probably invite you as a guest to present in the context of the liaison and our new charter 14:30:44 q+ 14:31:49 kaz: We have a liaison session where we could have the discussion 14:32:06 mm: Can we invite guests? 14:32:38 kaz: We can invite guests for the Breakout session, so probably can work something out 14:33:14 (FYI, the WoT F2F meeting will be held on 13-14 November, and the breakout sessions will be held on 12 November) 14:33:18 mm: Also the registration for remote participation is very cheap 14:34:03 q+ 14:34:29 Franck: What is the expected outcome of the Plugfest? 14:34:58 mm: Interoperability between WoT implementations and exploring new features 14:35:06 -> https://github.com/w3c/wot-testing/tree/main/events/2024.11.Munich GitHub for the previous Plugfest in Munich in November 2024 14:35:51 kaz: We usually create a Githob page to organize (link in the IRC) 14:36:29 s/Githob/GitHub/ 14:36:47 ... We can test some candidate devices 14:37:56 mm: the testing is focused on Thing Description document itself but we could focus more on device behavior conforming to expectations set by the TD 14:38:28 q- 14:39:03 Juanjo: We would like to explore how to connect devices to FiWare using Thing Description as one scenario 14:40:13 s/FiWare/FIWARE/ 14:40:22 ... There is another scenario we are more interested in is using using Thing Model as a language to create entities in the system using Thing Description 14:40:27 q+ 14:40:52 ... We may try to bring a Proof of Concept 14:41:06 ... We need to extend NGSI-LD to support actions 14:41:25 ... At least we will support Properties and Events 14:41:26 s/using using/using/ 14:41:59 mm: It only needs to do the basic operations to validate the TDs 14:42:49 The second scenario we are more interested it means using the Things Model language (abstract of Things Description Language) to describe Things for which NGSI-LD can be used to interface with. 14:42:55 mm: You could use the Thingweb Playground and TD validation tools 14:43:28 q? 14:43:31 q+ 14:43:35 ack k 14:43:55 kaz: What would you like to prioritize to work on by the time of the Plugfest? 14:45:20 Juanjo: The two parts are connected. We want to develop the use of ThIngModel as a language and create a Proof of Concept to test 14:45:40 ... In parallel we will work on the NGSI-LD extension for Actions 14:45:52 s/Plugfest?/Plugfest? Clarification on possible scenarios and use cases for Action binding? or actual implementation using your PoC for Plugfest?// 14:45:58 rrsagent, draft minutes 14:46:00 I have made the request to generate https://www.w3.org/2025/07/28-wot-ngsi-ld-minutes.html kaz 14:46:47 mm: There are 2 use cases; northbound and southbound, each with a set of issues 14:46:54 s|Plugfest?/|Plugfest?| 14:46:57 rrsagent, draft minutes 14:46:58 I have made the request to generate https://www.w3.org/2025/07/28-wot-ngsi-ld-minutes.html kaz 14:48:09 ... one is exporting TDs to validate, exposing NGSI-LD resources through TD, and the other is importing, consuming external resources as NGSI-LD through TD 14:48:40 ... The PoC can be limited to reading and writing Properties 14:49:17 ... You may encounter issues around dynamically created resources 14:50:31 Juanjo: It may not be an existing NGSI-LD system but a new design that can be created using ThingModel as the language 14:50:58 WoT Things Model language as the language for describing Thing classes. 14:51:19 mm: ThingModel can be used to dynamically create mew thing descriptions 14:51:28 s/mew/new 14:51:36 Instances of such Thing classes would be accessible through NGSI-LD. 14:52:41 mm: We should consider using the WoT use case process on Github issues 14:54:02 ( sharing Github screen and Use Case template ) 14:54:39 mm: It might make sense as we go forward to create some use cases and user stories 14:55:06 q+ 14:55:38 ack m 14:56:45 ack k 14:58:44 kaz: The core question is how to model Actions on the TD side also, possibly using ThingModel as a template for Actions 15:00:03 mm: Can we invite NGSI-LD to the Plugfest call on the 6th? 15:00:12 mjk: will do that 15:00:45 mm: AOB? 15:01:09 mm: will create a calendar entry foe August 26 15:01:16 rrsagent, draft minutes 15:01:17 I have made the request to generate https://www.w3.org/2025/07/28-wot-ngsi-ld-minutes.html kaz 15:01:23 mm: Adjourned 15:01:23 rrsagent, draft minutes 15:01:24 I have made the request to generate https://www.w3.org/2025/07/28-wot-ngsi-ld-minutes.html kaz 15:08:22 Martin has left #wot-ngsi-ld 20:10:32 Zakim has left #wot-ngsi-ld
