## N.3 Illustrative Mapping to ASE Concepts

The content of this section provides recommendations on how to express the concepts from draft ASE guidelines with measurement type concept names and concept name modifiers.

The leftmost column is the name of the ASE concept. The Base Measurement Concept Name is the concept name of the numeric measurement content item. The modifiers column specifies a set of modifiers for the base measurement concept name. Each modifier consists of a modifier concept name (e.g., method or mode) and its value (e.g., Continuity). Where no Concept Modifier appears, the base concept matches the ASE concept.
