====== 10.3 Conceptual Element to Logical Element / PIM ======
[[fxdemo:01-part:start | Go to Top ]]

A Conceptual Element traces to a [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Element / Platform Independent Model (PIM)]] when the logical architecture specializes the concept without binding it to a specific implementation technology.

For example, the concept [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoint]] may trace to a logical endpoint used for health reporting, work dispatch, transaction publication, validation results, policy decisions, or audit records. The logical endpoint remains [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|Platform Independent]]. It does not yet require DDS, REST, files, message queues, or another specific mechanism.

This [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] relationship helps reviewers confirm that the logical architecture preserves the conceptual meaning of the element it specializes.

Examples include:
