jsonschema - Need help :Json Schema Design -

i designing the json scheme. , facing issues while designing schema.

here problem.

i have array of group objects. , want array should contain unique group objects. want make them unique based on object id ( ex group.id)

the groups array not unique if (groups[0].id == groups[1].id) , want make unique based on group id, below json structure.

"groups": {         "type": "array",         "items": {"$ref": "#/group"},         "uniqueitems":true     },   "group": {         "type": "object",         "properties": {             "id": {"type": "integer"},             "type": {                 "type": "string",                 "enum": [                     "a",                     "b"                 ]             },             "command": {                 "type": "string",                 "enum": [                     "add",                     "modify"                 ]             }         }     }, 

well, there no magic bullet here. remind json-schema intended defining structure of json data (not values).

one option not consider groups node "array" instead "object", , use additionalproperties express additional properties should contain "type" , "command" properties.

then use name of each property in groups id, unique.

the problem approach not restrict id numeric (it might not acceptable in context). use patternproperties match "type,command" schema numeric "id's".
