As an Enterprise Architecture tool, the HOPEX Modeling application can be used to support an ArchiMate based EA initative on top of other frameworks and languages. Many different frameworks have been designed to help implement enterprise architecture projects. Even though common concepts can be retrieved in each framework, vocabulary may differ and sometimes the same words can be used with slight variations. HOPEX has made its own methodology choices and the vocabulary contained in the HOPEX Modeling tool metamodel reflects HOPEX's EA vision to be methodologically consistent over various frameworks.

Because of these differences, it is important to first establish the common vocabulary that will be used in the tool. For the HOPEX implementation of ArchiMate, the choice was made to use the ArchiMate vocabulary for ArchiMate users while keeping a common metamodel shared by all users.

HOPEX Archimate relies on an "aliasing" mechanism to present the ArchiMate vocabulary to ArchiMate users. Alias of concepts are defined upon the HOPEX standard metamodel and can be changed using HOPEX Studio. See "Concepts mapping", page 84.
