Working Session: Program Comprehension and Migration Strategies for Web Service and Service-Oriented Architectures

The migration to Web services has the potential of providing significant value to keeping legacy systems and components operational in a networked environment, a number of critical issues still need to be addressed. These issues can be classified in three categories; a) program comprehension and analysis issues; b) legacy system migration issues and; c) technology and standards issues. This paper discusses and debates approaches for addressing these issues. The paper's objective is twofold. First, is to explore the current state of the art in methods, tools and technologies that can assist in carrying out the required work and to identify a taxonomy of current approaches as well as, their strengths and weaknesses. The second objective is to identify open issues and research opportunities in the area of migrating legacy systems in Web enabled environments
