  • An ebXML Update - Latest News and Technology Globally ebXML technology has entered the mainstream with the Chinese government alone deploying 11,000 ebMS servers, and Europe and Asia committing to ebXML projects. Here in the US the healthcare community is moving to adopt ebXML with various initial projects underway and the US DOD EMall system is also using ebXML.  A selection of major industries including electrical utility, automotive and aerospace are in early stage adoption. To support all this ebXML is evolving rapidly and providing industry leading concepts and capabilities.  The new ebXML BPSS V2 from OASIS marks a watershed in this respect with context mechanisms, state mechanisms, support for using web services with ebXML, content transformation services and enhanced deterministic multiparty scenario modelling with forks and joins.  Similarly ebXML Registry V3 is now providing Semantic Web capabilities, and Federated Registry services. Put together the ebXML components now provide a richer and more complete foundation than ever before for robust and reliable electronic business.  This provides a service orientated architecture foundation that is globally deployable using open standards. This presentation will bring all this together and provide a comprehensive roadmap of the latest technology capabilities available through using ebXML today.

    Overall Needs for Business Process
  • BPSS key to eBusiness SOA
    • SOA
      • provides technology foundation and open interchange model and specifications
    • BPSS
      • formalizes this with business process control
      • captures the business exchange details
      • provides business agreement model for participants
      • provides facilitation for components in the SOA
      • XML template script sharable across an industry domain
      • context driven enables localization of standard models

  • ebXML SOA component options Business agreement Drives document exchanges Participant Profiles Domain Semantics Information Purposing Information Exchange
  • ebXML CPA / BPSS functions
    • ebXML BP identifies
    • Business processes including multi-party, multi-step exchanges
    • Roles an organization must play
    • Business transactions
    • Messages being exchanged
    • Context variables
    • Business rules of edge conditions
    • Transaction handling services
    • Error handling
    • ebXML CPA provides:
    • Service name and parameters
    • Endpoint for invocation
    • Role of an organization in the context of a service
    • Organization demographic information
    • Failure scenarios
    • Business process scenario and business transaction activity step

    • Transaction Messages being exchanged
    • Transport level QOS parameters
    • Certificate and Encryption configuration
    • Business status of agreement
  • Binary Collaboration Documents / Transactions Transport layer coupling Applying Context Modelling the process flow Download example model from: http://visualscripts.net/#ebxml Part 2 – Building a BPSS
  • What do I need to do?
    • A pplication – define the business purpose
    • B usiness interchanges + documents – itemize
    • C ollaborations, Content, Context – collect
    • D ocument exchanges – paint activity picture
    • E xceptions – succeed / fail / signal conditions
    • F low control – branching and choices
    • G o! – agree with your partners and distribute
  • Application – define business purpose
    • Business analysis – scope, goals, participants
    • Domain experts and users provide use cases
    • Information flows
    • Security needs
    • Application integration needs
    • Success criteria
    • Deployment community – eGov, Industry, Financial..
    • Technology needs
  • Business Transactions and Documents
    • Determine the exchanges involved in your business process
    • Label those transactions accordingly
    • Link to a specification for the detail of the actual document formats involved
    • Determine success and failure criteria and how these get notified
    • Note any context parameters that might apply from those business interchange details
    • Select the transport profile model to use for each exchange
  • Building the BPSS model Supply Chain Grants Application
  • Multiparty Model with BPSS V2 Automotive Supplychain Financial Marketplace
  • Step by Step Tutorial This summarizes the actions in the live demonstration
  • Build interchange details
    • Create headers for each of your transaction exchanges
  • Enter the document formats needed
    • Create document definitions and select type of identification
    • Specify location of document rules, and rules type
  • Add document links to transactions
    • In Transactions area add initiating and responded documents
    Initiate Transaction Provide Responses
  • Configure Fail / Succeed conditions
    • BPSS provides set of default conditions that marry to transport layer (ebMS) responses and outcomes
  • Choose / Configure Signal conditions
    • You can add a set of signals to your BPSS, these can be used to indicated pending process steps and intermediate events
  • Setup Business Exchange Profiles
    • Convenient profiles – pre-configured with typical interchange characteristics, and linked to the failure / success outcomes
  • Summary – configuring Transactions
    • Select behaviours from profiles, conditions and transport needs
    Configure Exchange Details
  • Summary – covered so far
    • A pplication – define the business purpose
    • B usiness interchanges + documents – itemize
    • Collaborations, Content, Context – collect
    • Document exchanges – paint activity picture
    • E xceptions – succeed / fail / signal conditions
    • Flow control – branching and choices
    • Go! – agree with your partners and distribute
  • How do we provide standard industry domain processes, but then be able to apply local criteria to those? Collaborations, Content, Context
    • Context is the pervasive driver to effective engineering
    • Drives dynamic process configuring and control
    • Ensures accurate information capture, packaging and delivery
    • Key to correct relationships between partners in a collaboration
    Understanding about Context Lack of context control mechanisms is the most prominent reason why legacy e-Business systems are difficult and complex to extend and support Date: circa 1568 1 : the parts of a discourse that surround a word or passage and can throw light on its meaning 2 : the interrelated conditions in which something exists or occurs
  • Generating a Context Instance
    • Add parameter value rules and document value rules
    Check a document and change a BPSS Parameter value Create a rule and set a value Configure Context Instance header
  • Context Summary
    • Context variables and values defined as needed
    • Business Partners review and Agree to its terms and outcomes
    • Registry can provide storage for the artifacts involved – business process script, XML context instance, CPA instance, CAM template – in a catalogue entry that therefore defines a reusable complete industry process package that can be context driven.
  • Worked example – completing the BPSS template Modelling the Process Flow
  • Summary of steps required
    • So far we have defined the:
      • Transactions
      • Documents
      • Success / Fail criteria
      • Transport exchange profiles
      • Context parameters
    • Now we have to complete the picture by building the actual activity flow
  • Start the Action Processes
    • Add Start block and beginning Transaction action
    Assign Transaction Assign Roles to participants Configure BPSS header
  • Next add responding action details
    • Responding block consists of success / fail actions
    Select associated responding document Group Possible Responses Configure outcomes and flow control Transport layer return settings
  • Decide next action details
    • Request continues based on what responder does
    Next action Fork on outcome and pick next action (conditions gated by external “beginsWhen” events within Transaction definition) Process Completes
  • The Complete Business Process
    • from the model – VisualScript generates actual XML instructions
  • Sharing Models Supporting Versioning and Tool integration Targetting deployment engines Download example model from: http://visualscripts.net/#ebxml Part 3 – Implementation Considerations
  • Sharing Models
    • The BPSS models can be shared in a variety of ways –
      • Save As : JPG, GIF, BMP, PNG, etc graphic
      • Generated to XML
      • Published to web via a web folder system
      • Saved in Registry
      • Can create library of pre-built components for a community or industry
  • Supporting Versioning and Tools
    • The XML syntax used to generate the BPSS model should be stored externally from the model itself
    • “include” instructions then retrieve the syntax when the model is generated
    • Then replacing the XML syntax files and regenerating the model automatically creates latest syntax, or a modified tool specific syntax
  • Targetting Deployment Engines
    • Whenever BPSS functional behaviour can be simulated by equivalent syntax used by a deployment engine – that syntax can potentially be output from the BPSS model
    • The BPSS model and approach is neutral to the middleware layer
    • If the middleware layer is using ebMS transport this emulation is likely to be especially straightforward
    • Some limited integration to WSDL based steps also is available in BPSS V2
  • Summary – covered so far
    • Business interchanges + documents – itemize
    • Collaborations, Content, Context – collect
    • Document exchanges – paint activity picture
    • Application – define the business purpose
    • Exceptions – success / fail conditions
    • Flow control – branching and choices
    • Go! – agree with your partners and distribute
  • Resources and Planning Summary
  • Providing Agile Information Systems
    • Ability to automatically configure business processing using neutral XML based scripting.
    • Lesson learned - three needs are paramount:
      • the ability to design transactions and processes consistently,
      • the ability to document their usage in a clear way and then
      • the ability to instruct software that can apply rules and test information context to dynamically manage those business processing exchanges
  • Next Steps
    • Work in progress:
      • Formal Publication of OASIS Specification V2
      • Library of BPSS templates by industry
      • Integration with OASIS Registry semantics
      • Integration with execution engines and ebMS
      • Development of BPSS models involving WSDL based exchanges and services
  • Get involved in OASIS ebXML-BP
    • Download the specs from www.oasis-open.org
    • Encourage your industry group to adopt BPSS templates for their standards
