HI-PLAN and Little-JIL: a Study of Contrast between Two Process Languages

摘要

A key issue for process languages is balancing the need for technical rigor with this need for ease of use. Little-JIL and HI-PLAN are new powerful, yet clear, process languages that attempt to resolve above two apparently conflicting objectives. This paper evaluates both the languages and provides valuable directions to the next-generation process language design. We describe their design goals and features, present solutions to a well-known benchmark process, ISPW-6 software process example, and analyze the relative strengths and weaknesses of each language through detailed comparisons on a wide variety of issues.
