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
