A Framework of Reflective Mechanism for Supporting OWL-S Requirements Specifications Evolution

The process of traditional requirements acquisition and analysis is generally completed by domain experts and requirements analysts, which will greatly restrict the requirements modeling automatization degree and userpsilas participation degree in the requirements process. This paper presents a reflective mechanism for evolution of requirements specifications (RMERS) that supports OWL-S. In the phase of requirements analysis, OWL-S is used to describe system requirements specifications, OWL-S^A is used to describe requirements change, the evolution of requirements specifications caused by userspsila individualized requirements is completed via reflective mechanism. Besides, this paper also explains the description language OWL-S^R of reflective requirements specifications of this reflective mechanism and the meta-information model. By means of this reflective mechanism, through evolution of OWL-S requirements specifications, the task of requirements analysis of networked software can be completed with high efficiency in the phase of requirements analysis.
