@rob-metalinkage you said `can a platform be a system of actuators` (and sensors). Yes, that's how most people look at it and that's exactly what I'm advocating for. But in the current version, a `Platform` is NOT a `System` unfortunately. I'm not sure what's the rational behind that. It seems like a very artificial distinction to me from the SSN viewpoint (especially since SSN already allows for hierarchical systems, for which platforms with payloads are typical use cases). @KathiSchleidt Again, I don't necessarily want to put things in the ` Platform` class that are `Sensor` or `Actuator` characteristics, but there are also (many) things that are related to the platform itself. Let's think again of the "battery capacity" example. For 99% of the moving platforms, it is the platform that provides power to all on-board sensors and actuators. In what sensor or actuator would you put this information? IMO the battery characteristics cannot be described by any of these sub-components because most likely they don't even have their own battery, so it has to be described at the platform level. More generally, mobile platforms have a bunch of characteristics on their own that are already defined by SSN: - http://www.w3.org/ns/ssn/systems/OperatingRange - http://www.w3.org/ns/ssn/systems/OperatingProperty - http://www.w3.org/ns/ssn/systems/SurvivalRange - http://www.w3.org/ns/ssn/systems/SurvivalProperty You can of course describe these for the sensors and actuators that the platform carries, but the platform (w/o payload) typically has these too. I find it too bad, that with the current model, we cannot explicitly use these properties on the `Platform` class. -- GitHub Notification of comment by alexrobin Please view or discuss this issue at https://github.com/w3c/sdw/issues/1411#issuecomment-1554177546 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
