 +
 +===== Statement =====
 +
 +The Logical Architecture / PIM SHALL define [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_definition|Logical Data Structure Definition]] and [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_instance|Logical Data Structure Instance]].
 +
 +===== Source =====
 +
 +Part 2, Section 16.5: Logical Information Requirements.
 +
 +===== Rationale =====
 +
 +The Logical Information Model requires both Logical Data Structure Definitions and Logical Data Structure Instances to distinguish reusable information definitions from their populated occurrences. This distinction supports platform-independent modeling, governance, interoperability, validation, traceability, and implementation mapping.
 +
 +Without these concepts, the Logical Architecture could not consistently distinguish information definitions from the information exchanged among Logical Nodes.
 +
 +===== Applies To =====
 +
 +This requirement applies to the Logical Information Model.
 +
 +It applies specifically to:
 +
 +  * Logical Data Structure Definitions;
 +  * Logical Data Structure Instances;
 +  * Logical Information Model; and
 +  * Domain Logical Profiles.
 +
 +===== Verification =====
 +
 +Verification SHALL confirm that the Logical Architecture / PIM defines both Logical Data Structure Definitions and Logical Data Structure Instances.
 +
 +Verification activities should include review checks confirming that:
 +
 +  * Logical Data Structure Definitions are explicitly defined;
 +  * Logical Data Structure Instances are explicitly defined;
 +  * the distinction between definitions and instances is maintained; and
 +  * both concepts remain platform independent.
 +
 +===== Traceability =====
 +
 +This requirement supports traceability between logical information definitions, logical information instances, and the information exchanged among Logical Nodes.
