Speci cation of Graphic Conventions in MethodsA

The current generation of CASE tools mainly provides rigid and unnexible support for editing, storage, veriication and transformation of speciications. Information engineers have to adapt their way of working to CASE tools instead of vice versa. To enable a more exi-ble, method independent, support of information engineers, the concept of a CASE shell has emerged. Crucial for CASE shells is the speciication 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 meta-modelling technique should also be able to represent graphic conventions in methods. An existing meta-modelling technique is extended with constructs for the representation of graphic knowledge.
