Towards Individualized Requirements Specification Evolution for Networked Software Based on Aspect

Networked software is a kind of Internet-based online complex software system produced through interaction and cooperation between networks and users who act as both consumer and producer of the system composed of web services. To meet a mass of individualized requirements, specifications for common requirements of the domain need to modify and evolve. Aiming at the concern, we propose a 3-step process of requirements evolution modeling of networked software. Focusing on the first step, the paper analyzes inducements for individualized requirements evolution, proposes a meta-model to describe the evolutionary requirements specification of networked software based on aspects, and presents a case study to demonstrate the usage of our approach. Finally a process for implementing the individualized requirements evolution is proposed. So it is helpful to guide the modeling for evolutionary requirements specifications and implement individualized requirements from common specifications.
