This function retrieves these properties and inserts them into the RDF graph with a proper subject.

  Parameters

  • sourceId: string

    temporary subject id for the external properties
  • newSubj: any

    subject for the external properties

  Returns Generator<any, void, unknown>

  iterator over referenced tables

  Returns Generator<CsvwTableDescription, void, unknown>
