Integrated specification of method and graphic knowledge

The current generation of CASE tools mainly provides rigid and inflexible support for editing, storage, verification and transformation of specifications. Information engineers have to adapt their way of working to CASE took instead of vice versa. To enable a more flexible, method-independent support of information engineers, the concept of a CASE shell has emerged. Crucial for CASE shells is the specification of interpretable method knowledge. A technique capable of specifying method knowledge is referred to as a meta-modelling technique. In this paper it is stressed that a met-modelling technique should also be able to represent graphic conventions in methods. An existing meta-modelling technique is extended With constructs for the integrated representation of method and graphic knowledge
