JSON Schema LD specification

JSON Schema for Linked Data, hereafter JSON-Schema-LD/json-schema-ld/jsc-ld, is a syntactic sugar for JSON Schema to enable generative interoperability by means of representing JSON schema in RDF vocabularies (RDF Schema) and RDF shapes (SHACL).

A JSON Schema is a declarative vocabulary specifies a number of rules to describe what objects serialized in JSON based format should look like. With JSC-LD, domain models and application profiles are extracted from existing implementation model in JSON Schema and represented in RDF Schema and Shacl shapes.
