Using enums with AJV's "select/selectCases" keyword - jsonschema

Question

Is it possible to give select a schema to match the case on?
The use case I have is that I want to select and match on a list of accepted values:
{
"type": "object",
"properties": {
"addressCountry": {
"type": ["string", "null"]
}
},
"select": {
"$data": "0/addressCountry"
},
"selectIf": {
"type": "string",
"enum": ["FR", "JP", "US", "NZ", "DE"]
},
"selectThen": {
"addressCountry": {
"type": "string"
}
}
}
EDIT: please note that selectIf and selectThen aren't keywords supported by AJV. It does support selectCases and selectDefault, however with selectCases you have to state each case individually. My question is more about if it's possible to match on multiple cases and use a single definition.

#Relequestual managed to help me solve this outside of SO. I didn't need to use select at all, could just use if/then/else like so:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"properties": {
"contactByPost": {
"type": "boolean"
},
"streetAddress1": {
"type": ["string", "null"]
},
"streetAddress2": {
"type": ["string", "null"]
},
"streetAddress3": {
"type": ["string", "null"]
},
"locality": {
"type": ["string", "null"]
},
"region": {
"type": ["string", "null"]
},
"postCode": {
"type": ["string", "number", "null"]
},
"country": {
"type": ["string", "null"]
}
},
"if": {
"type": "object",
"properties": {
"contactByPost": {
"type": "boolean",
"const": true
}
}
},
"then": {
"if": {
"type": "object",
"properties": {
"country": {
"type": "string",
"enum": ["JP", "US"]
}
}
},
"then": {
"type": "object",
"properties": {
"contactByPost": { "type": "boolean" },
"streetAddress1": { "type": "string" },
"locality": { "type": "string" },
"region": { "type": "string" },
"postCode": { "type": ["string", "number"] },
"country": { "type": "string" }
},
"required": ["streetAddress1", "locality", "region", "postCode", "country"]
},
"else": {
"type": "object",
"properties": {
"contactByPost": { "type": "boolean" },
"streetAddress1": { "type": "string" },
"locality": { "type": "string" },
"region": { "type": ["string", "null"] },
"country": { "type": "string" }
},
"required": ["streetAddress1", "locality", "country"]
}
}
}
Would provide the following results:
// Valid
{
"contactByPost": false
}
{
"contactByPost": true,
"streetAddress1": "123 Alphabet St",
"streetAddress2": null,
"streetAddress3": null,
"locality": "City",
"region": "State",
"postCode": "12345",
"country": "JP"
}
{
"contactByPost": true,
"streetAddress1": "123 Alphabet St",
"streetAddress2": null,
"streetAddress3": null,
"locality": "City",
"region": "State",
"postCode": "12345",
"country": "US"
}
{
"contactByPost": true,
"streetAddress1": "123 Alphabet St",
"streetAddress2": null,
"streetAddress3": null,
"locality": "City",
"region": "State",
"postCode": "12345",
"country": "NZ"
}
{
"contactByPost": true,
"streetAddress1": "123 Alphabet St",
"streetAddress2": null,
"streetAddress3": null,
"locality": "City",
"region": null,
"postCode": null,
"country": "NZ"
}
// Invalid
{
"contactByPost": true
}
{
"contactByPost": true,
"streetAddress1": "123 Alphabet St",
"streetAddress2": null,
"streetAddress3": null,
"locality": "City",
"region": null,
"postCode": null,
"country": "JP"
}
{
"contactByPost": true,
"streetAddress1": "123 Alphabet St",
"streetAddress2": null,
"streetAddress3": null,
"locality": "City",
"region": null,
"postCode": null,
"country": "US"
}
