A framework for promoting interoperability in a global electronic market-space
Lucas M. Venter, Maree Pather · 2005
The primary contributions to the area of electronic business integration, propounded by this thesis, are (in no particular order): (1) A novel examination of Business-to-Business (B2B) interoperability in terms of a multiplicity paradox and of a global electronic market-space a Complex Systems Science perspective. (2) A framework for an, integrated, electronic market-space, which is based on a hierarchical, incremental, minimalist-business-pattern approach. A Web Services-SOA forms the basis of application-to-application integration within the framework; The framework is founded in a comprehensive study of existing technologies, standards and models for secure interoperability and the SOA paradigm. The Complex Systems Science concepts of predictable structure and structural complexity are used consistently throughout the progressive formulation of the framework. (3) A model for a message handler (including a standards-based message-format) which obviates the common problems implicit in standard SOAP-RPC. It is formulated around the standardized, common, abstract application interface critical success factor, deduced from examining existing models. The model can be used in any collaboration context. (4) An open standards-based security model for the message handler. Conceptually, the framework comprises the following: (1) An interoperable standardized message format: a standardized SOAP-envelope with standardized attachments (8-bit binary MIME-serialized XOP packages). (2) An interoperable standardized message-delivery infrastructure encompassing an RPC-invoked message-handler - a Web service, operating in synchronous and/or asynchronous mode, which relays attachments to service endpoints. (3) A business information processing infrastructure comprised of: a standardized generic minimalist-business-pattern (simple buying/selling), comprising pre-specifications for business processes (for example, placing an order), standardized specific atomic business activities (e.g. completing an order-form), a standardized document-set (including, e.g. an order-form) based on standardized metadata (common nomenclature and common semantics used in XSD's, e.g. the order-form), the standardized corresponding choreography for atomic activities (e.g. acknowledgement of receipt of order-form) and service endpoints (based on standardized programming interfaces and virtual methods with customized implementations).
