General information
Name of the solution: CloudEvents validation service
Solution's owner: European Commission
A service to validate JSON events against the JSON representation of the CloudEvents specification. The CloudEvents specification offers a common structure and metadata for events that are published in event-driven systems (primarily cloud-native). The validation service allows validation against the specification's versions and additional checks against user-provided JSON schemas to check business rules specific to a given project's events.
The CloudEvents validation service implements the following:
Interoperability layers
Conceptual model
CloudEvents 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 16 | Multilingualism
The validator supports localisation in any of the official EU languages.
-
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.
