A service modeling approach with business-level reusability and extensibility.

This paper introduces a novel service modeling approach called VINCA_BS, which can be used by business people to extend the functionality of a service based software platform from a business perspective. VINCA_BS approach introduces the domain analysis approaches into service modeling and uses the domain requirement commonalities to define our VINCA business service models, which are user understandable, business level reusable service abstractions omitting concrete business details. These service models can be instantiated by different business people according to their actual business requirements that consequently add new functionalities to the platform. The approach has been successfully validated in a service based e-government project.Jianwu Wang, Jian Yu and Yanbo Ha
