OPEN (Object-oriented Process, Environment and Notation) is an international de
facto standard object-oriented development method developed and maintained by
the OPEN Consortium. OPEN consists of the OPEN Modeling Language (OML) as well
as process, metrics, etc. This book specifies OML, a small but vital component
of the complete OPEN method. It uses diagrams, tables, Web references and text
to present the syntax, semantics and rationale behind OML. It documents version
1.0 of OML so that object-oriented modelers can learn and use it, and upperCASE
vendors can support it.
