===== Statement =====

The Logical Architecture / PIM SHALL define logical information categories, including [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_message|Logical Message]], [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_event|Logical Event]], [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_command|Logical Command]], Logical Acknowledgement, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_assertion|Logical Assertion]], [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_record|Logical Record]], and [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_information_lineage|Logical Information Lineage]].

===== Source =====

Part 2, Section 16.5: Logical Information Requirements.

===== Rationale =====

Logical information categories classify information according to its architectural purpose rather than its implementation representation. Establishing these categories provides a consistent vocabulary for communication, governance, traceability, auditability, and later implementation mapping across all Domain Logical Profiles.

===== Applies To =====

This requirement applies to the Logical Information Model.

It applies specifically to:

  * Logical Messages;
  * Logical Events;
  * Logical Commands;
  * Logical Acknowledgements;
  * Logical Assertions;
  * Logical Records; and
  * Logical Information Lineage.

===== Verification =====

Verification SHALL confirm that the Logical Information Model defines each required logical information category.

Verification activities should include review checks confirming that:

  * each logical information category is explicitly defined;
  * each category has a distinct architectural purpose;
  * categories remain platform independent; and
  * Domain Logical Profiles preserve the inherited information categories.

===== Traceability =====

This requirement supports traceability between Logical Data Structure Instances and their architectural information categories.
