This chapter contains reference information on writing target system descriptions. These descriptions are the only source of information on the behavior of the target system, providing an effective separation of the target characteristics from the implementation of the transformation toolbox.
This chapter is divided into three major parts. The general notions underlying the description model are presented in section 2.1. The recommended organization of the actual description files is given in section 2.2. Sections 2.3 through 2.7 detail the components of target descriptions. For each concept represented in a target system description, these sections present the corresponding constructs, their syntax, and the associated semantical constraints when applicable.
