Mapping Concepts

A map effectively describes the following to NCL:

• The names that will be used to reference various components within an MDO
• The relationship between these data components
• The means of identifying each component
• The way in which the data is represented

Until a map is associated with an MDO, NCL cannot reference components in the data by name. However, NCL can still process the MDO as a whole.
