As a reader you may wonder why we choose this image for the cover of the book.
This is actually hard to find relevant images for our software engineering field. In addition to be sometimes abstract, some terms doesn’t ends up with appropriate pictures ( for example, looking for “models” in image database invariably results with fashion girls.)
The cover image actually uses the”breathing life into” metaphor. One of the tool presented in the book (Kermeta) uses that metaphor too “breathing life into your metamodel” since its version 1, back in 2005.
This tries to illustrate one of the core idea of the book that is making your models useful and transforming ideas and knowledge into living artifacts.
It also convey the idea that the techniques proposed in the book are not limited to software.
