Developing Distributed Software Systems by Incorporating Meta-Object Protocol (diMOP) with Uni ed Modeling Language (UML)

Although object-oriented paradigm is becoming a more realistic approach to the development of largescale software systems, the existing object-oriented notations and methodologies do not fully support the development of distributed object systems. In this paper, we integrate Meta-Object Protocol (MOP) into a de facto standard object-oriented modeling language UML together to build a software architecture for distributed object systems. We propose a high-level extension of conventional MOPs, called diMOP which helps to develop distributed object systems by realizing a re ective architecture. To incorporate diMOP with UML, we introduce two new speci cation languages: Class Diagram Supporting diMOP (CDSM) and Dynamically Con gurable Object-oriented Statemachine (DCOS), which are proposed to replace the class diagram and the state diagram of UML. The two speci cation languages support to specify dynamic con guration behaviors as well as to incorporate the diMOP. This paper gives a methodology to develop e ciently distributed object systems through UML
