Properties

Optional @context

@context: Context

A JSON-LD Context for the query. In an API, this will frequently be implicit. For example, using json-rql as the body of a POST to http://example.com/my-api/v1/person/query might have the implicit context of a Person (possibly found at http://example.com/my-api/v1/person).

examples

Optional @id

@id: Iri | Variable

The unique identity of the subject in the domain.

🚧 Subjects strictly need not be identified with an @id, but the data of such Subjects cannot be retrieved with a simple Describe query.

Optional @type

@type: Iri | Variable | Iri[] | Variable[]

The type of the subject, as an IRI or set of IRIs. (@type is actually shorthand for the RDF property rdf:type.)
