DS~3I-A Dynamic Semantically Enhanced Service Selection Infrastructure

摘要

Service-oriented computing (SOC), lately often in combination with business process modeling (BPM), is becoming reality in current enterprise systems. At the same time, process models do no longer only span different departments but more and more frequently multiple organizations. Current BPM approaches focus on syntactic specification of work flow structures and necessitate static service allocation during modeling time. Dynamic service allocation at runtime based on the semantics of service descriptions, however, allows for much more flexibility. This paper presents DS~3I as a concept and implementation for semantically enhanced dynamic service selection. DS~3I and its semantic middleware components are based upon an ESB and semantic annotations of services and allows for one-step service selection at runtime of a process.
