How to define schema for Map<String, String>

[venkatpselvam1]

I have a simple java dictionary as HashMap<String, String>. The sample json will look like the below format. The no of elements in the dict may be zero or more. The values are not complex object the are simple strings. How can I write a validator for this?

{
   "a": "a1",
   "b": "b1",
   "c": "c1",
   "d": "d1",
}

The keyword you want is additionalProperties.

{
  "type": "object",
  "additionalProperties": {
    "type": "string"
  }
}

This keyword will validate any properties that don't appear in properties or patternProperties.
