The concept of “model” is today considered as a promising technology in domains such as
data and software engineering. In the field of model engineering, models are now viewed as
firts-class entities. This new approach makes it possible to envision the integration of models
into engineering processes. Such an integration will however require a set of dedicated tools
enabling to perform standard model operations onto handled models. We strongly believe that,
in order to achieve usability for large communinities of users, model-based tools have to rely
on a common and well-defined theorical modeling framework.
This report addresses both theorical and implementation issues. We propose the idea that a
common set of principles may be mapped to different implementation contexts. We illustrate
our approach with AMMA, our current proposal for a model-based conceptual architecture.
