Business processes, business documents Business processes, business documents Transport, routing, packaging Transport, routing, packaging Electronic Business • Application-to-Application • Business Process Automation • RosettaNet (vertical solution) • ebXML (horizontal framework) Company A Company B ERP ERP Automatic Negotiation of CPA

  8. Semantic Web • The Semantic Web is a vision: the idea of having data on the web defined and linked in a way that it can be used by machines not just for display purposes, but for automation, integration and reuse of data across various applications • See “W3C Semantic Web Activity,” by Marja-Riitta Koivunen, for more descriptions. Automatic Negotiation of CPA

  9. Semantic Web • The Semantic Web is the new generation of the World Wide Web, based on the semantic network knowledge representation formalism, which enables packaging information in the form of object-attribute-value statements, so called triplets. • By assuming that terms used in these statements are based on the formally specified meaning (for the community of interest), i.e. ontologies, these triplets can be semantically processed by machine agents.

  11. The Big Picture of SW Automatic Negotiation of CPA (http://semanticweb.org/about.html#bigpicture)

  12. Remainder • Introduction to ebXML framework • Creating agreement of collaboration protocol between trading partners • Introduction to CPPA • Agent-mediated architecture for the negotiation of collaboration protocols • Working examples • Conclusion Automatic Negotiation of CPA

  13. The ebXML Framework at Work Automatic Negotiation of CPA

  14. Components of the ebXML Framework • BPSS (Business Process Specification Schema) • Defining how public business-processes are described • ebCC (Core Components) • Defining the semantics of business documents that are exchanged in public processes • CPP (Collaboration Protocol Profile) • Definition of services and the constraints in using the services • CPA (Collaboration Protocol Agreement) • Description of the mutual agreement between the business partners to carry out the public business process • RR (Registry and Repository) • Protocols and store for registering, storing, and retrieving public business processes and associated business documents, and CPPs • ebMS (Message Services) • A standard way to send and receive messages between business partners Automatic Negotiation of CPA

  44. Conclusion • EB automation, including the automation of implementation, discovery, and run-time phases • Agent-mediated architecture for the automation of discovery phase • A prototype system is developed to show the concept of automation. • Future work • Using UMM to formalize the negotiation protocol in BPSS • Using the agent-mediated architecture to develop the automatic negotiation of products trading, probably replacing the CPPs by terms of condition Automatic Negotiation of CPA
