NAF Terminology
To bridge the gap between both worlds (HOPEX and NAF) and simplify the appropriation of the NAF application by a NAF expert, the HOPEX metamodel has been translated and the notions used renamed.
This section therefore details the mapping made between the HOPEX and NAF concepts used.
The table below lists the concepts renamed with their standard definition (from the HOPEX perspective) and the NAF definition. The aim of this renaming is to make the mapping between the NAF concepts and the HOPEX concepts as invisible as possible for the user.
