The bi-annual symposium “Communication in Distributed Systems” (KiVS 2007) will be held from February 26th to March 2nd at the University of Bern, Switzerland. The special focus topic of KiVS 2007 are “Peer-to-Peer Systems”. There will be also five collocated workshops on special topics in the area of communication and distributed systems:

  • 4th Workshop on Mobile Ad-Hoc Networks (WMAN’07)
  • Autonomic Networking
  • Network Security: Secure Network Configuration
  • Self-organized, context-sensiteive distributed systems (SAKS’07), and
  • Service-oriented Architectures and Service-oriented computing (SOA/SOC)

Especially the “Service-oriented Architectures and Service-oriented computing (SOA/SOC)” workshop is an excellent oppurtunity showing the international standardization aspects and road to success around the remaining open issues of an efficient collaboration and interoperability between business partners based on Service-oriented Architectures. Therefore, Christoph Schroth, and Till Janner of SAP Research CEC St. Gallen, together with Gunther Stuhec, SAP AG Walldorf, will show how both business semantic and application interoperability could be successfully enabled by bridging together the semantic oriented standards from UN/CEFACT and the Services-Oriented Architecture. The following contribution paper will give more details about UN/CEFACT and SOA:

Existing concepts of SOA mainly concentrate on technological issues and must be extended toward the semantic level to ensure that different applications have the same understanding of the business meaning of services. This presentation is a proposal to composite the set methodologies for common modeling of business information and collaborative business processes on business semantic level issued by the UN/CEFACT that bridges the semantic gap existing in current SOA deployments by introducing a loose coupling between the meaning of business data and its representation. This standards composite builds upon an evolutionary and collaborative approach and supports the modeling of both commonly comprehensible business documents and collaboration processes, and will be a key part fostering cross-organisational interoperability. Some UN/CEFACT methodologies play a key role in SAP’s Enterprise Service Oriented Architecture (Enterprise SOA). They describe how to represent the semantics and distinguish Web Services as Enterprise Services. Therefore, the new primary and reusable building blocks for business information in SAP NetWeaver™ are based on the so called UN/CEFACT CCTS (Core Component Technical Specifcation) approach that is used to build business information on semantic level. The so-called SAP GDTs (Global Data Types) are provided by the SAP NetWeaver XI™ and can be used equally and without loss of information internally in ABAP or Java applications.
