 +
 +===== Statement =====
 +
 +The Logical Architecture / PIM SHALL distinguish [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Logical Nodes]] from runtime deployments, implementation artifacts, deployment artifacts, execution mechanisms, and communication technologies.
 +
 +===== Source =====
 +
 +Part 2, Section 16.2: Distributed Node-Based Architecture Requirements.
 +
 +===== Rationale =====
 +
 +The Logical Architecture is platform independent. Separating Logical Nodes from implementation and deployment concepts preserves architectural meaning while allowing multiple implementation approaches to realize the same logical participant.
 +
 +===== Applies To =====
 +
 +This requirement applies to the definition, interpretation, maintenance, review, and implementation mapping of the Logical Architecture / PIM.
 +
 +It applies specifically to:
 +
 +  * Logical Nodes;
 +  * Implementation Profiles;
 +  * Deployment Profiles; and
 +  * Technology mappings.
 +
 +===== Verification =====
 +
 +Verification SHALL confirm that Logical Nodes remain distinct from implementation and deployment concepts.
 +
 +Verification activities should include review checks confirming that:
 +
 +  * Logical Nodes are not defined as runtime artifacts;
 +  * implementation technologies do not redefine Logical Nodes;
 +  * deployment mechanisms do not redefine Logical Nodes; and
 +  * implementation mappings preserve the logical meaning of each Logical Node.
 +
 +===== Traceability =====
 +
 +This requirement supports traceability between Logical Nodes and the implementation artifacts that realize them.
