DESCRIPTION¶
This Catmandu::Importer can be use to import RDF data from URLs, files or input
streams. Importing from RDF stores or via SPARQL is not supported yet.
By default an RDF graph is imported as single item in aREF format (see
RDF::aREF).

- file
- fh
- encoding
- fix
- Default configuration options of Catmandu::Importer.
- url
- URL to retrieve RDF from.
- type
- RDF serialization type (e.g. "ttl" for RDF/Turtle).
- base
- Base URL. By default derived from the URL or file name.
- ns

predicate and datatype URIs. Set to 0 to disable abbreviating URIs. Set to
a specific date to get stable namespace prefix mappings.
