JSON Schema Resolver

implproposal

Derive schema definitions from external JSON schema files.

Scope

When this extension is enabled schema references can point to JSON schema files in addition to local fragments. The reference can be either a URL or a relative path to a file in resources/schemas. It also supports referencing sub-schemas in $defs. Examples:

  • https://example.com/buildings.json
  • https://example.com/buildings.json#/$defs/address
  • buildings.json
  • buildings.json#/$defs/address

Limitations

Compositions are only supported to some extent:

  • oneOf Only the first variant is used.
  • anyOf Only the first variant is used.
  • allOf The first variant is used as main schema. Properties from additional variants are merged into the main schema.
