TriX Format

Description​

TriX is an XML serialization for RDF graphs. IterableData parses TriX with rdflib and yields one triple record per statement (subject, predicate, object). It is read-only in this release.

File Extensions​

  • .trix — TriX RDF/XML-style graphs

Implementation Details​

Reading​

  • Loads an rdflib.Graph and parses with format="trix"
  • Accepts filename or stream text
  • Materializes all triples as string-valued dicts

Writing​

Writing is not supported. Use Turtle or RDF/XML when write support is needed.

Key Features​

  • XML RDF: interoperates with TriX producers
  • Triple rows: consistent SPO dict shape with N3/TriG (without graph)
  • rdflib backed

Usage​

from iterable import open_iterable

with open_iterable("data.trix") as source:
    for triple in source:
        print(triple["subject"], triple["predicate"], triple["object"])

Parameters​

No format-specific iterableargs.

Installation​

pip install 'iterabledata[rdf]'

Requires rdflib.

Limitations​

  1. Read-only
  2. Memory: full graph in memory
  3. Requires rdflib
  4. Named-graph structure in TriX is flattened to triples as exposed by rdflib’s Graph parse

Error Handling​

  • ImportError: missing rdflib — install iterabledata[rdf]
  • Parse errors: invalid TriX from rdflib
  • I/O errors: missing or unreadable files
  • Format is registered writable=False
