About Cayley

Cayley is an open-source graph database platform designed to manage and query linked data efficiently. Inspired by the graph database technologies behind Freebase and Google's Knowledge Graph, it supports multiple linked data formats including RDF, NQuads, and JSON-LD. Cayley is built to operate on top of existing databases, whether SQL, NoSQL, or key-value stores, enabling flexible integration without requiring data migration.

The platform is highly modular, allowing enterprises to extend its capabilities with new data formats, backends, query languages, or custom logic. It supports multiple query languages such as Gizmo (a Gremlin dialect), MQL, and GraphQL dialects, catering to diverse developer preferences. Cayley is community-driven and developed under the Apache 2.0 license, making it freely available for enterprise use. It is well-suited for organizations seeking an open, extensible graph database solution to enhance their data analytics and knowledge graph initiatives.
