Roles are temporary functions played by objects (e.g. the person that is the arresting officer or the subject in a law enforcement case).
Each role references the base object with the @id keyword from JSON-LD.
Here is an example of a NIEM role j:ArrestOfficial in JSON schema:
{
"$id": "http://release.niem.gov/niem/domains/jxdm/6.0/",
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"additionalProperties": false,
"definitions": {
"j:EnforcementOfficialBadgeIdentification": {
"$ref": "./nc.schema.json#/definitions/nc:IdentificationType",
"description": "An identification used to refer to an enforcement official."
},
"j:EnforcementOfficialType": {
"additionalProperties": false,
"description": "A data type for a person involved in the enforcement of law.",
"properties": {
"j:EnforcementOfficialBadgeIdentification": {
"description": "An identification used to refer to an enforcement official.",
"$ref": "#/definitions/j:EnforcementOfficialBadgeIdentification"
},
"nc:RoleOfPerson": {
"description": "A person of whom the role object is a function.",
"$ref": "./nc.schema.json#/definitions/nc:RoleOfPerson"
}
},
"required": [
"nc:RoleOfPerson"
],
"type": "object"
}
},
"properties": {
"j:ArrestOfficial": {
"$ref": "#/definitions/j:EnforcementOfficialType",
"description": "A peace official who makes an arrest."
},
"nc:Person": {
"$ref": "./nc.schema.json#/definitions/nc:PersonType",
"description": "A human being."
}
},
"required": [
]
}
This schema references other schemas: nc and xs
