RDF

YAML Schema to RDF Generator

Generate a JSON LD representation of the model

context: list[str] = None

emit_metadata: bool = False

end_schema(output: str | None = None, context: str = None, **_) → str

Visited once at the end of generation

@param kwargs: Arguments passed through from CLI – implementation dependent

generatorname: ClassVar[str] = 'rdfgen.py'

Name of the generator. Override with os.path.basename(__file__)

generatorversion: ClassVar[str] = '0.1.1'

Version of the generator. Consider deprecating and instead use overall linkml version

original_schema: SchemaDefinition = None

//github.com/linkml/linkml/issues/871

Type:

See https

uses_schemaloader: ClassVar[bool] = True

Old-style generator that uses the SchemaLoader and visitor pattern

valid_formats: ClassVar[list[str]] = ['ttl', 'hext', 'json-ld', 'n3', 'nquads', 'nt', 'nt11', 'ntriples', 'patch', 'trig', 'trix', 'ttl', 'turtle', 'xml']

Allowed formats - first format is default

visit_all_class_slots: ClassVar[bool] = False

False means only visit own slots, True means visit all slots

Type:

Visitor ClassVar

CLI

gen-rdf
