Examples are either introduced explicitly in prose (e.g. Non-Normative PortionsĪll contents of this document are normative except portions explicitly declared as non-normative.Įxamples in this document are non-normative, and are presented to aid understanding of introduced concepts and the behavior of normative portions of the specification. See Appendix A for more details about the definition of algorithms and other notational conventions used in this document. Implementers are encouraged to include equivalent but optimized implementations. Algorithms described in this document are written to be easy to understand. “Let completedResult be the result of calling CompleteValue()”) is to be interpreted as having at least the same level of requirement as the algorithm containing that step.Ĭonformance requirements expressed as algorithms can be fulfilled by an implementation of this specification in any way as long as the perceived result is equivalent. Any algorithm referenced within an algorithm step (e.g. “Return the result of calling resolver”) are to be interpreted with the same level of requirement as the algorithm it is contained within. Conforming AlgorithmsĪlgorithm steps phrased in imperative grammar (e.g. These key words may appear in lowercase and still retain their meaning unless explicitly declared as non-normative.Ī conforming implementation of GraphQL may provide additional functionality, but must not where explicitly disallowed or would otherwise result in non-conformance. The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in the normative portions of this document are to be interpreted as described in IETF RFC 2119. Conformance requirements are described in this document via both descriptive assertions and key words with clearly defined meanings.

If your organization benefits from GraphQL, please consider becoming a member and helping us to sustain the activities that support the health of our neutral ecosystem. The GraphQL Foundation was formed in 2019 as a neutral focal point for organizations who support the GraphQL ecosystem, and the GraphQL Specification Project was established also in 2019 as the Joint Development Foundation Projects, LLC, GraphQL Series. This specification was licensed under OWFa 1.0 in 2017. The development of this open standard started in 2015. This is the specification for GraphQL, a query language and execution engine originally created at Facebook in 2012 for describing the capabilities and requirements of data models for client-server applications.
