It is unclear where json-schema syntax can be used

[fhirter]

from the rules object of the example it is not clear where standard json-schema syntax can be used and library syntax is needed.

It seems that when, then, otherwise, is, actions are keywords from the library, while this oject in is is json-schema.

const rules = {
  dailyTemp: {
    when: [
      {
        weather: {
          params: {
            query: '{{city}}',
            appId: '{{apiKey}}',
            units: '{{units}}',
          },
          path: 'main.temp',
          is: {
            type: 'number',
            minimum: '{{hotTemp}}',
          },
        },
      },
    ],
    then: {
      actions: [
        {
          type: 'log',
          params: { message: 'Quite hot out today!' },
        },
      ],
    },
    otherwise: {
      actions: [
        {
          type: 'log',
          params: { message: 'Brrr, bundle up!' },
        },
      ],
    },
  },
};

If this is correct, a simple rule could be written as:

const rules = {
  simple: {
    when: [
      {
        weather: {},
          is: {
            type: 'object',
            properties {
               temp: {
                 type: 'number'
               }
            }
          },
        },
      },
    ],
}

Is this correct?
