A Core Component-Based Modelling Approach for Achieving e-Business Semantics Interoperability

The adoption of advanced integration technologies that enable private and public organizations to seamlessly execute their business transactions electronically is still relatively low, especially among governmental bodies and Small and Medium-sized Enterprises (SMEs). Current solutions often lack a common understanding of the underlying business document semantics and most existing approaches are not able to cope with the huge variety of business document formats, stemming from highly diverse requirements of the different stakeholders. Developed and applied in the course of the EU-funded research project GENESIS, this paper presents a comprehensive core component-based business document modelling approach that builds upon existing standards such as the OASIS Universal Business Language (UBL) and the UN/CEFACT Core Component Technical Specification (CCTS). These standards are extended by introducing the concept of generic business document templates out of which specific documents can be derived according to the actual user’s needs. Key principle to achieve this flexibility is the integration of business context information that allows for modelling standard-based but at the same time customized business documents. The resulting modelling framework ranges from (tool-supported) graphical data models to the technical representation of the business documents as XML schema documents designed in compliance with the UN/CEFACT XML schema Naming and Design Rules (NDR).
