Modeling versus reuse.  During the last 10 years a change of focus seems to have 

happened in the object-oriented community. From being mainly interested in reuse of 

code, the focus has shifted to analysis and design. We argue that there should be a 

balance between these extremes to fully realize the benefits of the potential for object-

orientation to integrate analysis, design and implementation.

oriented modeling should be formulated independently of the languages. This 

separation is necessary to avoid limiting the developer by the (current) expressive 

power of the languages and to produce new requirements for language design.
