A Comparison Study of Viewpoint Approaches in Service Enterprise Architecture

Management on inter-enterprise collaborations (business networks) still face grand challenges especially in terms of managing interoperability of nonfunctional properties (NFPs) at various levels (technical, semantic, pragmatic). This paper identifies three categories of nonfunctional properties (collaborative for business level, contractual for communication issues, extrafunctional for computational dependability) and describes how facilities are provided in the Pilarcos architecture for declaring, negotiating and enforcing agreed nonfunctional properties on collaborating business services and their joint activities.
