                                                 3
Web Services
 Bottom-up approach to SOA
 Consists of three main specifications:
    Web Services Description Language (WSDL)
    Universal Description Discovery and Integration
     (UDDI)
    Simple Object Access Protocol (SOAP)




                                                       4
Web Services Issues
 Only provide protocols for interoperation, not defining
  how the business process should be conducted
 Proprietary extensions and vendor-specific add-ons




                                                            5
ebXML

    Language
   Joint initiative between United Nations Centre for
    trade Facilitation and Electronic Business
    (UN/CEFACT) and Organization for the Advancement
    of Structured Information standards (OASIS)
   A set of specifications that enable a modular electronic
    business framework
   ebXML.org
   freebXML.org
                                                               6

What is ebXML
 A SOA aims to provide specifications for:
    Business processes & collaboration (ebBP)
    Collaboration protocol profile and agreements (CPPA)
    Core data components (CCTS)
    Messaging (ebMS)
    Registries and repositories
 Consists of five core components
    ISO 15000-1: ebXML Collaborative Partner Profile Agreement (CPPA)
    ISO 15000-2: ebXML Messaging Service Specification (MSG)
    ISO 15000-3: ebXML Registry Information Model (RIM)
    ISO 15000-4: ebXML Registry Services Specification (RS)
    ISO 15000-5: ebXML Core Components Technical Specification (CCTS)



                                                                         9
ebXML Collaborative Partner Profile and Agreement
(CPPA)
 Collaboration Protocol Profile
    Technical capabilities to engage in e-business
     collaborations with other partners
 Collaboration Protocol Agreement
    Agreed configuration of public, shared aspects of the
     protocols used in the business collaboration protocols




                                                              10
ebXML Messaging Services
 Delivering Electronic Data Interchange (EDI)
    transactions within XML
   EDI transactions can be orders, shipping, invoices,
    etc.
   Not restrict to only EDI documents
   Message can contain payloads of any format type
   Transfer over HTTP and SMTP
   Business-level header
   Application-level message authorization

                                                          11
ebXML Registry
 ebXML Registry Information Model
 ebXML Registry Services Specification
 Contains Collaboration Protocol Profiles




                                             12
How does ebXML work
 A service client looks up ebXML registry for service
  provider’s Collaboration Protocol Profile (CPP)
 The CPP describes the provider’s electronic
  capabilities
 The service client then matches the CPP description
  with its own to find commonalities, and creates a
  Collaborative Partner Agreement (CPA) to send to the
  service provider
 The service provider validates and accepts the CPA,
  and the transaction begins
                                                         13
ebXML Benefits
 It defines a business process
 Top-down approach, provides a common framework
  for vendors to conduct business
 Built on existing Web services technologies, such as
  XML, SOAP, etc




                                                         14
Conclusion
 ebXML solves current issues with Web services
    Defines a common business process which companies
     can follow
    Eliminating vendor-specific extensions by defining
     industry standards
 Can replace current Web services architecture
