Module rdf_star 

RDF-Star Parsing and Serialization Infrastructure

This module provides trait definitions and shared infrastructure for parsing and serializing RDF-Star (SPARQL 1.2) data across multiple formats.

All parsers converge on Virtual IDs (TAG_EMBEDDED | 60-bit hash). All serializers diverge from Virtual IDs to format-specific syntax.

Enums
