====== 6.2.1 Domain ======

[[dido:03-dido-te:06-information-model:06-02-test:start|Go to 6.2 Test]]

The source model associates a [[dido:99_annexes:annex-b-terms-and-definitions:d:domain|Domain]] with **Test**.

===== Relationship to Test =====

^ Domain per Test ^ Tests per Domain ^ Relationship ^
| ''0..1'' | ''0..*'' | A Test may be associated with zero or one Domain. A Domain may be associated with zero or more Tests. |

===== Architectural Meaning =====

The Domain relationship places a Test within the governance and semantic context represented by that Domain.

The relationship does not, by itself, define the policies, requirements, configurations, or other governed constraints that apply to the Test. Those relationships are established through the corresponding DIDO-TE information elements and requirements.

===== Model Refinement Considerations =====

[[dido:03-dido-te:99-annexes:annex-b-references:dte-004|[DTE4]]] permits a Test to be associated with zero or one Domain.

Whether DIDO-TE should require every Test to be associated with exactly one Domain remains to be determined during normalization of the DIDO-TE Information Model.

The relationship between Domain and the [[dido:99_annexes:annex-b-terms-and-definitions:t:test_definition|Test Definition]] also requires review. In particular, DIDO-TE must determine whether:

  * Domain is associated with Test and inherited by the Test Definition;
  * the Test Definition references its governing Domain directly; or
  * both relationships are required for [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]].

No change to the [DTE4] source-model multiplicity is made on this page.

===== Notes for Editors =====

  * The canonical semantics of Domain are maintained in the shared Terms and Definitions corpus and are transcluded above.
  * Do not duplicate or redefine Domain semantics on this page.
  * Preserve the [DTE4] source-model multiplicities until a deliberate DIDO-TE refinement is approved.
  * Record any change to Domain cardinality as a DIDO-TE model refinement rather than as a correction to [DTE4].
  * Review the Domain-to-Test Definition relationship when the Test Definition model is developed in Section 6.13.
