Wot-thing-description: Add "multipleOf" term to NumberSchema and IntegerSchema

Created on 5 Nov 2019 · 6Comments · Source: w3c/wot-thing-description

It is ideal if we could indicate the resolution of number properties, such as "targetTemperature" of HVAC being specified in 0.5 degrees Celsius step.
JSON Schema already has "multipleOf" keyword for numeric types, so it is desirable to incorporate it to NumberSchema and IntegerSchema in future TD version.

Propose closing JSON Schema

Part of such TD looks like this:

{
  ...
  "properties": {
    "targetTemperature": {
      "type": "number", 
      "minimum": 16, 
      "maximum": 30, 
      "multipleOf": 0.5
    }
  }
  ...
}

The current TD spec allows addition of such extra words that would be parsed by a JSON Schema library. Could you provide example implementation TDs that make use of this?

In 2019-11-08 TD telecon, it was suggested to support this in the next version of TD spec.
