Describing Services for Service Ecosystems

Service ecosystems are electronic market places and emerge as a result of the shift toward service economies. The aim of service ecosystems is to trade services over the internet. There are still obstacles that impede this new form of market places. Two of these challenges are addressed in this paper: (1) identification of appropriate service properties to specify service descriptions, and (2) a need of a clear classification for service description notations. Therefore, service properties and their relationship are introduced and an adaption for the Zachman Framework is presented to classify service description notations depending on the relative perspective.

Service value properties for service ecosystems: a reference model and a modeling guideline

With the rise of service-oriented computing and web service ecosystems, services and their electronic descriptions become crucial to foster significant value propositions toward potential service consumers. While there exist ample technical specifications to describe web services, conceptual approaches are rare. On top of this, an alignment between business models and information technology is lacking. This paper is a step toward this direction in that it offers a reference model to classify service value descriptions depending on their purpose, presents a generic model for service properties, proposes two meta models for conceptual modeling, and finally introduces a modeling guideline.
