Semantic Web

• The Semantic Web is a vision:

• See “W3C Semantic Web Activity,” by Marja-Riitta Koivunen, for more descriptions.

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

http://www.w3.org/Talks/2001/1102-semweb-fin/Overview.html


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.

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

1. Any Party may register its CPPsto an ebXML Registry.

2. Party B discovers trading partner A (Seller) by searching in the Registry and downloads CPP(A) to Party B’s server.

3. Party B creates CPA(A,B) and sends CPA(A,B) to Party A.

4. Parties A and B negotiate and store identical copies of the completed CPA as a document in both servers. This process is done manually or automatically.

5. Parties A and B configure their run-time systems with the information in the CPA.

6. Parties A and B do business under the new CPA.

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
