jsonschema multiple values for string property
If you want data to be one of a fixed set of exact values, you can use enum:
{ "type": "string", "enum": ["stop", "go"]}So, to fit this in your example, try:
{ "type": "object", "properties": { "$gte": { "type": "string", "oneOf": [ {"pattern": "<some-pattern>"}, {"enum": ["TOKEN", "ANOTHER_TOKEN"]} ] } }}
In addition to what already said, for the date you can use "date" within the "oneOf"
