图形处理挑战在现代数据库系统中很常见，属性图数据模型得到了广泛的采用。由于该领域的新奇，图数据库和框架通常提供自己的查询语言，例如Neo4j的Cypher，TinkerPop的Gremlin和SAP HANA的GraphScript。这些语言通常缺乏数据模型和语义的正式背景。为了解决这个问题，openCypher计划的目标是扩展Cypher语言的一个子集，目前它提供语法规范和一组验收测试，以允许供应商实现其openCypher兼容引擎。
Graph processing challenges are common in modern database systems, with the property graph data model gaining widespread adoption. Due to the novelty of the field, graph databases and frameworks typically provide their own query language, such as Cypher for Neo4j, Gremlin for TinkerPop and GraphScript for SAP HANA. These languages often lack a formal background for their data model and semantics. To address this, the openCypher initiative aims to standardise a subset of the Cypher language, for which it currently provides grammar specification and a set of acceptance tests to allow vendors to implement their openCypher compatible engine.
