ARC supports 4 serialization formats:
The serializers can process both index and triple structures. Some examples:
Each ARC component provides shortcuts to the serializers. These convenience methods auto-detect the passed structure (resource index or triple set):
- RDF/XML
- RDF/JSON (following the Talis proposal)
- Turtle
- N-Triples
