openCypher is an open-source specification of the Cypher property graph query language, including grammar, TCK test suites, and language resources for implementers. It is evolving incrementally toward ISO/IEC 39075 GQL, the ISO property graph query language standard.
Use cases
- implement Cypher query language support in a graph database
- run the Cypher technology compatibility kit against my graph engine
- learn the Cypher grammar and language semantics
- prepare my graph database for the ISO GQL standard
- find the official openCypher specification documents
- report issues or propose changes to the Cypher language spec
When to choose
- you are building a graph database or graph processing tool that supports Cypher
- you need the authoritative grammar, TCK, and language resources for Cypher
- you want to track the convergence of Cypher toward ISO GQL
When to avoid
- you need a runnable query engine or driver rather than a specification
- you want a general-purpose graph analytics library
- you need a fully GQL-conformant implementation today, since openCypher only converges incrementally
