Integrating HR offices over semantically enriched SOA

Integration of heterogonous systems is an important issue today. Service Oriented Architecture (SOA) is usually the choice of software vendors to solve the problem. However it provides a system independent way for the communication, SOA does not offer a common model for the used data structures. Moreover different applications are using different structures for the same real world entities. Integrating these systems can not be handled directly by standard SOA tools and methodology. Our new approach will demonstrate how to solve the integration problem of InterJob Executive Search Company working with various heterogonous systems. To integrate the systems of branch offices of InterJob a new pool service and semantic concepts were introduced. Our approach adds semantics as meta-data to the services and performs automatic data transformation in process run-time. Original services are encapsulated and new services are published applying a common interface. The branch offices are able to communicate with each other, using these new services for the data exchange.
