I went to an interesting meetup yesterday about WoT, with guest speakers from the W3C and Jeo. It was all about the efforts to standardize a representation of capability and interop of various IoT devices to bring them an off the shelf ease of integration. Very good it was. Anybody want to by a used car? Just a little humour there.
Quite a few hidden units would be needed, with character similar to mol, and likely u for micro, and maybe even getting each unit down to just one letter. Just how much would be possible with 26 units? Assuming things like space and time resolution (or the more operative protocol and not base quantities) could use the JSON key of such a unit, and the value could be expressed in the providing units. There could for example be provided 2 virtual units which expressed measure of input and output, so say 2 rad per second output could obviously be considered a motor speed controller. The $ key could express the primary capability, and the say the “per second output range” specifier in the sub object could specify the rad per second output per seconds range. And the “rad per second output range” specifier could key the speed range in rad per second.
It’s all vague at present, but that’s the meetup purpose. Nice time guys, and gals.
