Property Graph Python Packages

xbrlkit

Read SEC and ESEF XBRL filings locally: parse once with Arelle into a portable model, export to TAVI, xBRL-JSON, JSON-LD or a LadybugDB property graph (one filing or many stacked), and query it with Cypher or from any MCP client.

graflo

Describe a labeled property graph once in a YAML manifest; GraFlo builds the schema and ingests records from CSV, JSON, Parquet, SQL, RDF/SPARQL, REST APIs or Kafka into ArangoDB, Neo4j, TigerGraph, FalkorDB, Memgraph, NebulaGraph, PostgreSQL or a directory on disk.

onya

Knowledge graph expression, serialization, and Python implementation. Useful for LLM context.

polypack-db

Generic property graph engine with vector similarity search — extracted from scrollstr's PolyGraph

overgraph

Absurdly fast embedded graph database with built-in vector search. Rust core, Node.js and Python connectors, GQL, graph algorithms, all in-process with no server.

ison-graph

ISONGraph is a multi-language property graph library designed specifically for LLM and AI applications. It provides the most token-efficient way to represent graph data in LLM context windows while maintaining high accuracy for graph-based reasoning tasks.

deltagraphar

A transactional, time-traveling property-graph store on GraphAr, versioned with LakeFS.

graphyne

Graphyne is a smart graph - a property graph capable to actively reacting to changes and incorporating decision making logic, written in Python. It is designed to be easy to integrate into your Python projects, simple to use and very powerful. It uses Memetic as its graph definition and query language. It is capable of running with or without persistence.

bluegraph

Python framework for graph analytics and co-occurrence analysis

robosystems-xbrl-holon

Read SEC and ESEF XBRL filings locally: parse once with Arelle into a portable model, export to TAVI, xBRL-JSON, JSON-LD or a LadybugDB property graph (one filing or many stacked), and query it with Cypher or from any MCP client.
