What is openCypher?

The openCypher project aims to deliver a full and open specification of the industry’s most widely adopted graph database query language: Cypher.

Focus on Your Domain

Graphs naturally describe your domain, and Cypher lets you focus on that domain instead of getting lost in the mechanics of data access. Both expressive and efficient, Cypher is intuitive and immediately familiar.

Human Readable

Cypher is a human-readable query language that makes common operations easy. A combination of English prose and intuitive iconography, Cypher is accessible to developers and operations professionals alike.

Complete Open Source Access

The openCypher project means you can use Cypher as your query language for graph processing capabilities within any product or application. Databases like SAP HANA Graph, Redis, AgensGraph and Neo4j all use the Cypher query language – now you can too.

     MATCH (d:Database)-[:USES]->(Cypher)-[:QUERIES]->(:Model:Graph)
     WHERE d.name IN ['SAP HANA Graph','Redis','AgensGraph', 'Neo4j',...]
     RETURN Cypher.features

The openCypher project aims to improve growth and adoption of graph processing and analysis by providing an open graph query language to any data store, tooling or application provider as a mechanism to query graph data.

  • Provides a query language with full support
  • Makes graph processing and analysis easier to adopt
  • Grants vendor independence to all users
  • Eases graph integration with other data platforms

Most of our activity happens on the GitHub repository, where you may for example submit or comment on CIRs (Cypher Improvement Requests). The Slack link points to a sign-up page, which will give you an invitation to the neo4j-users Slack team, where we live in the #opencypher channel.
