APS treats its core concepts as systematically related rather than as a collection of independent terms. Changes to one canonical definition can therefore affect how other concepts and relationships within the framework are interpreted.

The APS glossary provides conceptual infrastructure for maintaining these definitions and relationships. It stabilises terminology, records canonical formulations, preserves important distinctions, and makes the consequences of conceptual revision easier to identify across the framework.

This establishes a practical relation between conceptual organisation and glossary structure:

  • Conceptual organisation: identifies and maintains relevant relationships among APS concepts.

  • Glossary structure: provides a controlled implementation through which those concepts and relationships can be recorded, compared, and revised.

The glossary is therefore more than an auxiliary reference resource, but its organisation does not itself establish biological dependencies or explanatory claims. Those claims retain their own evidential and comparative burdens.
