Applicable Issues

#148

Description of the Change

  • Lift the JSON schema version to Draft 2020-12
  • Declare required link types in schemas, to make validations more failsafe and simple
  • Step major version of all event and object schemas, except for ArtD that is still below 1.0 and therefore cannot be raised to 1.0 in this PR.

Alternate Designs

  • Instead of duplicating info about required link types into the links yaml object we could have parsed the _links object and evaluated the required link types from there. That would have made it a single source of truth for declaring required link types. But the drawbacks are a more complex json generator and also possibly a lacking possibility to specify what version of the generic EiffelEventLink definition to use per event type. As a mitigation for this a check has been implemented to compare the links object with the _links object.
  • Could also have included validation of available link types, not just the required ones, but in line with comments in JSON schema doesn't have link objects validations for Eiffel events  #148 that might not be desired. A separate issue could be raised to discuss whether or not to validate available link types as well, and how to deal with custom link types if so.

Benefits

Validation of required links in json schema instead of being hard coded in each event publisher implementation

Possible Drawbacks

Previously approved events could now be disallowed, if the event producer accepted events without some required link types as described in the md docs.

 _description: |-
   The EiffelEnvironmentDefinedEvent declares an environment which may be referenced from other events in order to secure traceability to the conditions under which an artifact was created or a test was executed. Depending on the technology domain, the nature of an environment varies greatly however: it may be a virtual image, a complete mechatronic system of millions of independent parts, or anything in between. Consequently, a concise yet complete and generic syntax for describing any environment is futile.

   The EiffelArtifactReusedEvent declares that an identified [EiffelArtifactCreatedEvent](./EiffelArtifactCreatedEvent.md) has been _reused_ for an identified [EiffelCompositionDefinedEvent](./EiffelCompositionDefinedEvent.md). This means that it is logically equivalent to an artifact that would have been built from that composition, and can be used for build avoidance (see the [Build Avoidance Usage Example](../usage-examples/build-avoidance.md) for more information).

   The EiffelEnvironmentDefinedEvent declares an environment which may be referenced from other events in order to secure traceability to the conditions under which an artifact was created or a test was executed. Depending on the technology domain, the nature of an environment varies greatly however: it may be a virtual image, a complete mechatronic system of millions of independent parts, or anything in between. Consequently, a concise yet complete and generic syntax for describing any environment is futile.
