Graph Exchange File Format

GEFF is a specification for a file format for exchanging spatial graph data. It is not intended to be mutable, editable, chunked, or optimized for use in an application setting.

This repository contains two packages:

• geff-spec is the specification of GEFF metadata written with pydantic BaseModels which are exported to a json schema for use in other languages.
• geff is the python library that reads and writes GEFF files to and from several python in-memory graph data structures (networkx, rustworkx and spatial-graph).

Learn more in the documentation or check out the source code.

Installation

pip install geff
