rdflib collections flattening graph
Decision gist · record as of 2026-08-14
No. The package is abandoned (last updated 2018-11-20) with no maintenance signal, high install friction from source-only distribution, and uncertain compatibility with modern Python versions. If you need RDF collection support, consider whether rdflib's native collection handling or an actively maintained alternative better serves your project's long-term stability requirements.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.6+ and rdflib; package is read-only and assumes well-formed RDF collections per RDF spec conventions.
- High install friction due to source-only distribution.
- The package is abandoned (last commit 2018-11-20, no releases in 2824 days), so expect no maintenance, bug fixes, or compatibility updates for modern Python versions beyond those it was tested against.

What it is and what it does
CFGraph is a specialized extension of rdflib's Graph class designed to flatten RDF collections into a more intuitive list representation. RDF uses a linked-list structure (with rdf:first and rdf:rest predicates) to represent ordered sequences, which can be cumbersome to navigate directly. CFGraph interprets these structures as Python lists, making it easier to work with collection data in RDF documents.
The package is read-only: it parses existing RDF collections but does not convert Python lists back into RDF collection syntax. It assumes collections follow standard RDF conventions for well-formedness (empty lists as rdf:nil, single elements with rdf:first/rdf:rest pairs, and blank nodes as subjects). The implementation was last updated in 2018 and is no longer maintained, so compatibility with recent Python or rdflib versions is uncertain.
Use it for
- Parse RDF documents containing ordered collections and access them as native Python lists.
- Simplify navigation of linked-list RDF structures in semantic web data processing pipelines.
- Read RDF collections from ontologies or knowledge graphs without manual rdf:first/rdf:rest traversal.
- Integrate RDF collection flattening into rdflib-based data extraction workflows.
