Abstract

This paper discusses how MSC-2000 could influence the Sequence Diagrams within UML 2.0, and why the UML 1.x semantics is partly inadequate for what is needed in the area of sequence charts. Extracts of a possible UML meta-model is shown and this can be understood as a conceptual model for MSC-2000 as well and an indication of an approach to the future MSC-2000 semantics. UML Collaboration Diagrams have no direct counterpart in SDL/MSC and the difference between sequence diagrams and collaboration diagrams is analyzed.
