Abstract. 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.
