5.3 How These Concepts are Used in the Knowledge Hierarchy

This knowledge hierarchy is set up to associate and retrieve different levels of information for data objects exchanged between applications, for each of the levels of the hierarchy defined in Section 5.1 Features, Interpretations, Representations , and Properties and shown in Figure 5-1 . For more information how to specify the relationships among these different data objects, see 5.4 Specifying Relationships in RESQML .

We have four levels of the knowledge hierarchy (informally referred to as "FIRP"):

Feature

Interpretation
