Franck: Will be out until the 26th <kaz> [10]https://www.timeanddate.com/worldclock/ converter.html?iso=20250826T120000&p1=137&p2=43&p3=250&p4=tz_at &p5=1440&p6=136&p7=195&p8=101&p9=33&p10=236&p11=248 [10] https://www.timeanddate.com/worldclock/converter.html?iso=20250826T120000&p1=137&p2=43&p3=250&p4=tz_at&p5=1440&p6=136&p7=195&p8=101&p9=33&p10=236&p11=248 McCool: Is everyone available on the 26th at 2 hours earlier than this slot? (no objections) McCool: August 26th, 8AM US Eastern Liaison information Kaz: Still waiting for response ¡K we should ask about status Franck: The work is being moved to a new TC ¡K Next we will create a proposal McCool: what is the priority in your group? Franck: there is a round table today where we will discuss new projects McCool: So there is an intent to go forward, and you are organizing things? Franck: Yes McCool: We are working on our new WoT charter, which is both a distraction and an opportunity to accommodate new activities Kaz: WoT Working groups are chartered for 2 years, and our current charter ends in September. We want to include the NGSI-LD collaboration in the new charter McCool: We need to have a discussion in the larger group about the new charter Juanjo: Who will take over the NGSI-LD advocacy? Koster: I will handle that Plugfest McCool: The plugfest is taking place in November at the annual W3C TAPC conference in Kobe, Japan ¡K We plan to present the outcome of the Plugfest at a conference session ¡K We are planning to offer remote connectivity for the Plugfest and there is a remote participation option for TPAC Juanjo: We have a presentation McCool: We could probably invite you as a guest to present in the context of the liaison and our new charter Kaz: We have a liaison session where we could have the discussion McCool: Can we invite guests? Kaz: We can invite guests for the Breakout session, so probably can work something out <kaz> (FYI, the WoT F2F meeting will be held on 13-14 November, and the breakout sessions will be held on 12 November) McCool: Also the registration for remote participation is very cheap Franck: What is the expected outcome of the Plugfest? McCool: Interoperability between WoT implementations and exploring new features <kaz> [11]GitHub for the previous Plugfest in Munich in November 2024 [11] https://github.com/w3c/wot-testing/tree/main/events/2024.11.Munich Kaz: We usually create a GitHub page to organize (link in the IRC) ¡K We can test some candidate devices McCool: the testing is focused on Thing Description document itself but we could focus more on device behavior conforming to expectations set by the TD Juanjo: We would like to explore how to connect devices to FIWARE using Thing Description as one scenario ¡K There is another scenario we are more interested in is using Thing Model as a language to create entities in the system using Thing Description ¡K We may try to bring a Proof of Concept ¡K We need to extend NGSI-LD to support actions ¡K At least we will support Properties and Events McCool: It only needs to do the basic operations to validate the TDs <jhierro> 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. McCool: You could use the Thingweb Playground and TD validation tools Kaz: What would you like to prioritize to work on by the time of the Plugfest? Clarification on possible scenarios and use cases for Action binding? or actual implementation using your PoC for Plugfest? 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 ¡K In parallel we will work on the NGSI-LD extension for Actions McCool: There are 2 use cases; northbound and southbound, each with a set of issues ¡K 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 ¡K The PoC can be limited to reading and writing Properties ¡K You may encounter issues around dynamically created resources Juanjo: It may not be an existing NGSI-LD system but a new design that can be created using ThingModel as the language <jhierro> WoT Things Model language as the language for describing Thing classes. <jhierro> Instances of such Thing classes would be accessible through NGSI-LD. McCool: ThingModel can be used to dynamically create new thing descriptions McCool: We should consider using the WoT use case process on Github issues ( sharing Github screen and Use Case template ) McCool: It might make sense as we go forward to create some use cases and user stories Kaz: The core question is how to model Actions on the TD side also, possibly using ThingModel as a template for Actions McCool: Can we invite NGSI-LD to the Plugfest call on the 6th? Koster: will do that McCool: AOB? McCool: will create a calendar entry foe August 26 McCool: Adjourned Minutes manually created (not a transcript), formatted by [12]scribe.perl version 244 (Thu Feb 27 01:23:09 2025 UTC).
