 +===== Statement =====
 +
 +A [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_definition|Logical Data Structure Definition]] SHALL describe the structure, meaning, and constraints of an information class at the platform-independent logical level.
 +
 +===== Source =====
 +
 +Part 2, Section 16.5: Logical Information Requirements.
 +
 +===== Rationale =====
 +
 +Logical Data Structure Definitions establish the platform-independent description of information used throughout the architecture. Separating logical definitions from implementation schemas preserves conceptual meaning while allowing multiple implementation technologies to realize the same logical information structure.
 +
 +===== Applies To =====
 +
 +This requirement applies to all Logical Data Structure Definitions within the Logical Architecture / PIM.
 +
 +It applies specifically to:
 +
 +  * Logical Data Structure Definitions;
 +  * Logical Information Model;
 +  * Domain Logical Profiles; and
 +  * Implementation Profiles.
 +
 +===== Verification =====
 +
 +Verification SHALL confirm that each Logical Data Structure Definition describes the structure, meaning, and constraints of an information class.
 +
 +Verification activities should include review checks confirming that:
 +
 +  * information structures are explicitly defined;
 +  * semantic meaning is documented;
 +  * logical constraints are identified; and
 +  * implementation technologies do not redefine logical information structures.
 +
 +===== Traceability =====
 +
 +This requirement supports traceability between logical information definitions and the implementation representations that realize them.
 +
