Easy way to group custom defined types to use for reference? - jsonschema

Question

How to reference types by group instead of doing it individually?
For example here, I want "sum" and "subtract" types to accept types that are "number"-related types only("number", "sum", "subtract"). While "concatenate" can accept both "number" and "string"-related types. Including their selves. This will be really helpful for me if in case I added more types and want them to be automatically included.
"sum": {
"title": "sum",
"type": "object",
"properties": {
"values": {
"type": "array",
"items": {
"anyOf": [
{
"type": "number"
},
{
"$ref": "#/definitions/sum"
},
{
"$ref": "#/definitions/subtract"
}
]
}
}
},
"required": [
"values"
]
},
"subtract": {
"title": "subtract",
"type": "object",
"properties": {
"minuend": {
"type": "number"
},
"subtrahend": {
"type": "number"
}
},
"required": [
"minuend",
"subtrahend"
]
},
"concatenate": {
"title": "concatenate",
"type": "object",
"properties": {
"strings": {
"type": "array",
"items": {
"anyOf": [
{
"type": "number"
},
{
"type": "string"
},
{
"$ref": "#/definitions/sum"
},
{
"$ref": "#/definitions/subtract"
}
]
}
}
},
"required": [
"strings"
]
}
}
Here's the full schema:
{
"definitions": {

"items": {

{
"type": "number"
},
{
"$ref": "#/definitions/sum"
},
{
"$ref": "#/definitions/subtract"
}
]
}
}
},
"required": [
"values"
]
},
"subtract": {
"title": "subtract",
"type": "object",
"properties": {
"minuend": {
"type": "number"
},
"subtrahend": {
"type": "number"
}
},
"required": [
"minuend",
"subtrahend"
]
},
"concatenate": {
"title": "concatenate",
"type": "object",
"properties": {
"strings": {
"type": "array",
"items": {
"anyOf": [
{

},
{

},
{
"$ref": "#/definitions/sum"
},
{
"$ref": "#/definitions/subtract"
}
]
}
}
},
"required": [

]
}
},
"title": "Step",
"type": "object",
"properties": {
"value": {
"oneOf": [
{
"type": "number",
"minimum": 0
},
{
