EIF Perspective attributes of GraphQL validation service

General information

Name of the solution: GraphQL validation service

Solution's owner: European Commission / DG Informatics (DIGIT) - Interoperability solutions for public administrations, businesses and citizens (ISA²)

Description:

An online service to validate GraphQL queries against their target schemas. The validator is based on the GraphQL reference implementation and expects as input the query to validate as well as the schema to validate against. Both can be provided directly or as remote URI references, with the schema also being able to be pre-configured to provide a fixed validator for a specific project’s API.

Type of solution: Assessment tools

The GraphQL validation service implements the following:

Interoperability layers

Conceptual model

GraphQL validation service implements the following EIF recommendations as explained below:

  • Recommendation 4 | Openness

    Open specifications can be supported by validators and conformance testing artefacts, implementing requirements as executable assertions. The definition of validators alongside published specifications facilitate their development, adoption and usage, but also create a level playing field as conformance can be verified in a deterministic and unbiased manner.

  • Recommendation 8 | Technological neutrality and data portability

    The Test Bed's validators promote integration via technology-agnostic service APIs, allowing them to be used in any environment regardless of its pre-existing technology stack. In addition, validators offer multiple deployment models that make minimal assumptions on available infrastructure.

  • Recommendation 9 | Technological neutrality and data portability

    The key focus point of the Test Bed's validators is semantic interoperability to ensure that data is produced and consumed as prescribed by agreed specifications.

  • Recommendation 17 | Administrative simplification

    All Test Bed validators as well as the Test Bed conformance testing software, support the testing of solutions that realise digital public service channels.

  • Recommendation 33 | Technical interoperability

    All Test Bed validators as well as the Test Bed conformance testing software are based upon the open GITB specifications and are themselves published as open source software. In addition, they support open specifications with validation and conformance testing of solutions at a semantic and technical level.
