Title

Model view

Identifier

SWIM-SERV-026

Requirement

A service description should

• include a model view on the conceptual parts, expressed using a formal and standardised notation, that formalises the representation of the business logic of its service interfaces, service operations and exchanged information; and
• declare the notation used to express the model view.

Rationale

Exposing the business logic of the service in a formalised notation and standardised notation allows operational and technical experts to understand how the service works and make comparisons.

Verification

Completeness: If the model view is provided, verify that the notation is declared; and verify that the model view fully covers service interfaces, service operations and exchanged information.

Consistency: If the model view is provided, verify that the model view is consistent with the service description (e.g. same service operation name).

Correctness: If the model view is provided, verify that the model view is aligned with the declared notation.

Examples/Notes

Note: It is recommended to use the UML as notation.

Note: The model view covers structural and activity diagrams when using UML as notation.

Note: The SESAR ISRM Foundation 8 is an example of a formal and standardised notation [RD 6].
