Hi all, Attached you find the example for which I see a problem with the dereferenceable URIs. *** Presentation heavily makes use of animations! *** Assumptions: I want to have a single URI for the Room as this identifies the room – this is what applications need to know + the URL of their IoT Broker. I have two domains. Applications in the two domains do not have direct access to each other’s infrastructure, infrastructure components (IoT Broker, IoT Discovery) may have only have one-directional access (i.e. one to the other but not the other way round). The room may have been originally identified by a third provider/domain (domain/infrastructure may no longer exist). The applications want to access the same information, i.e. for the given room based on its ID / URI. All what I describe works perfectly well with NGSI v1 – I need to make sure it still does with v2, … Best regards, Martin ------------------------------------------ Dr. Martin Bauer Senior Researcher NEC Europe Ltd.

In order to make it agile, I propose to start with a core team of people really involved in the NGSI implementations and definition. If you miss anyone from your teams or other teams, please add them to the loop. I’ll be out of the office most of the week, so I’ve set up a doodle poll to start the discussing starting by Friday. Please fill in the poll considering a 90 min meeting. http://doodle.com/poll/e2akwctqnfvdbez6 The goal of the meeting will be: 1. To set up the strategic framework about NGSI adoption and ways to evolve. (15 min) 2. To have a presentation of Gilles’ proposal with Q/A to understand it in depth. (60 min) 3. To set up subsequent calls to analyse impact on endorsement and existing implementations and AOB (15 min) Best Regards, Sergio. -- Sergio Garcia Gomez Telefonica (TI+D) SmartCity Solutions / FIWARE Parque Tecnologico de Boecillo. 47151 Boecillo (Valladolid), SPAIN.
