A free model (FEM) provides a context-free environment for modeling any kind of objects or systems. It is generally associated with a set of extensions, which allow you to define your own concepts and graphical symbols.
For example, you could create a model to represent:
how your models and documents relate to each other
the organizations in your enterprise and how they interrelate
a flowchart
a hierarchy diagram
the graphics you use in PowerPoint presentations and link them to the presentations they are used in
the users in your Enterprise Repository and link them to symbols representing the groups they belong to
an ORM model using ORM specific extended model definitions
You can enrich the diagrams in the Free Model by selecting different bitmaps for each symbol and add extended attributes to collect specific metadata. VBScript and the Generic Generator make it possible to program your own semantics into this model and create specific generated code or other output particular to your own interpretation.
