  1. EbXML TM Technical Architecture Overview www.ebxml.org Editor:Duane Nickull Constributors: All ebXML Committees, participants V 0.3 (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  2. Part One What is ebXML? (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  3. ebXML™ “Creating a Single Global Electronic Market™” A United Nations – CEFACT / Oasis sponsored initiative (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  4. ebXML Mission . . . To provide an open XML-based infrastructure enabling the global use of electronic business information in an interoperable, secure and consistent manner by all parties. (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  5. ebXML Architecture • Providing a view for integration of business processes among ad-hoc or established independent business partners by electronic means. • Reducing the need for collaborative business partners to have individual and expensive prior agreement on how to integrate business processes. • Providing a high-level business-centric view of distributed e-business processes. • Supporting and representing business processes independent of the technical solution. • Providing and supporting a library of common, standard intra-business processes • Allowing for both business processes and enabling technologies to evolve independently while retaining long-term investments in both. • Integrating with new and legacy systems throughout the enterprise • Leveraging existing technologies and standards (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  7. ebXML Architecture At the heart of ebXML is a powerful system of Registries and Repositories A Repository is a storage tank for Meta data such as Mapping Templates, business rules, “smart” document DTD’s, dictionaries, libraries and other core components for electronic business Repository Registry (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  8. ebXML Core Components Core components are elements of the component library that are common to multiple business domains. Core Components are Business Objects horizontal to many organizations. Examples can be an address on an invoice, a telephone number or a legal requirement to reply with confirmation of receipt of a purchase order. (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  9. Part Two - ebXML Mapping / Rendering A review of ebXML Mapping / Rendering Architecture (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  10. ebXML Templates • Provide semantic information for “smart” business documents. • Ideally utilize a “declarative” approach to transformations. Small footprint. • ebXML Mapping / Renderiing Templates are expressed in valid XML syntax only. • They are authored and owned by standards bodies, businesses or organizations who wish to interoperate within the ebXML Architecture. Repository Mapping Templates (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  11. ebXML Registries & Repositories • A Registry is an interface to allow “Process Owners” to submit or update their mapping templates. • A Registry has two interfaces – one for applications (API) and one for Humans (Manual HTTP) • A Security protocol is use to offer authentication, protection and non-repudiation benefits. • Once the XML syntax has been validated, the Mapping Template is placed into the Repository. API Human Interface Repository SECURITY LAYER Registry Syntax Validation (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  12. EbXML Repository Search Requirements • Once the Mapping Templates are stored in a Repository, a search and retrieval mechanism must be employed. • The XML Repository Search engine must provide: • A Web Search interface for humans to manually locate data • An API for applications to rapidly access stored data • A caching mechanism (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  13. EbXML Repository Search Requirements • A mechanism will be deployed to meet the Search and Retrieval needs for an ebXML Repository. • It must spider the Repository and creates a searchable index of the XML-syntax data. • A cache is created • A machine API to the Cache is used XQI API Human Search Interface XML index mechanism XML Cache API Human Interface SECURITY LAYER Registry Repository Spiders the Repository Syntax Validation (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  14. How ebXML Trading Partners Interact • A Trading Partner creates a Mapping Template The Mapping Template Editor then sends a copy of the Template to the Registry. Trading Partner (ebXML Compliant) ebXML Application GUI Editing Tool API Human Interface SECURITY LAYER Registry (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  15. How ebXML Trading Partners Interact • The trading Partner can now send a business transaction to another ebXML capable trading partner. • The transaction sent to the second partner can be classified in three distinct categories - Meta Information, Technical Information and Business Information. Trading Partner #1 (ebXML Compliant) Trading Partner #2 (ebXML Compliant) Business Interchange (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  16. ebXML Transactional Architecture Trading Partner #1 (ebXML Compliant) Trading Partner #2 (ebXML Compliant) Business Interchange • The Business transaction will be expressed in syntax that conforms to XML (current version is 1.0). The Business Information will be neutral but may need to use entity references to comply with the XML syntax requirements. (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  17. ebXML Architecture • The first part of the message will be the Processing instructions expressed in the document type declaration • A multibyte character set will be used to help facilitate diverse language characters <?xml version=“1.0” encoding=“UTF-8”?> [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  18. ebXML Architecture • The message will use a root tag of <ebxml> to identify it as an ebXML compliant transaction. <?xml version=“1.0” encoding=“UTF-8”?> <ebXML> </ebxml> [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  19. ebXML Architecture • The next component is the routing information (a technical component). Each message must have enough information in this section to uniquely identify each party and be able to address each party on the Internet. <?xml version=“1.0” encoding=“UTF-8”?> <ebXML> <routing verion=“1.0”> <from>Trading Partner 1</from> <to>Trading Partner 2</to> </routing> </ebxml> [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  20. ebXML Architecture • The next component is the Meta data component for identifying the business process, the version of that process, the owner of the process and where another application can retrieve a mapping template to apply to the business data component. <?xml version=“1.0” encoding=“UTF-8”?> <ebXML> <routing></routing> <process type=“Purchase_Order” version=“1.17” owner=“FOOBAR_EDI” location=www.foorepository.com/maps/> </ebxml> [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  21. ebXML Message Architecture The <process> element is a mechanism to provide information that will allow a unique Mapping Template to be retrieved and applied to the business content of the message. … <process type=“Purchase_Order” version=“1.17” owner=“FOOBAR_EDI” location=“foorepository.com/maps”/> … [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  22. ebXML Message Meta Architecture • The “type” attribute: • Is used to uniquely identify the process type in conjunction with the “owner” and “version” attributes. • Any combination of characters can be used as long as they are legal in XML syntax. • Can be used with other attributes to locate a specific Mapping Template in a Repository [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  23. ebXML Message Meta Architecture • The “version” attribute: • Is used to identify a specific version of a process unique to each process “owner” • Not to be confused with the “version” attribute of the <routing> element which is used to maintain state within a transaction • Standard conventions of major.minor should be applied (ie version=“1.17”) [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  24. ebXML Message Meta Architecture • The “owner” attribute: • Is used to identify a the organization who “owns” the process being identified. • Any combination of characters can be used as long as they are legal in XML syntax • A shared Registry/Repository will be used to provide unique identification and assign “Owner” names. [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  25. ebXML Message Meta Architecture • The “location” attribute: • Is used to retrieve Mapping Templates or UML modelling of the process. • Ideally will utilize http to point to this information [note: This entire section will be elaborated on by Messaging Group] (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  26. ebXML Architecture • When Trading Partner #2 receives the incoming message, it gets handed to the ebXML application by the server interface that receives it. • The ebXML application then checks it’s own cache to see if the process Mapping Template is available in the correct version. TP #1 TP #2 EbXML Application Local Cache Human Search Interface XQI API XML Cache Index Repository Registry (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  27. ebXML Architecture • If the process is available, the transaction can be acted upon. • If it is not found, the ebXML Application must then check the repository cache via the API • If a Template is found, the transaction can now be acted upon. TP #2 EbXML Application Local Cache Human Search Interface XQI API XML Cache Index Repository Registry (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  28. ebXML Architecture • A third stage “Manual” search can be employed to locate a similar Mapping Template. For example, v 1.17 may not be available however, 1.17 is. The Template Editor can now be used to manually create the template by TP #2 TP #2 EbXML Application Manual Search Local Cache Human Search Interface XQI API XML Cache Index Repository Registry (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)

  29. ebXML Architecture • A Search logic is employed by the application to determine Mapping Templates abstracts. If a MT to map X12 to cbXML is available and an MT to map cbXML to HL7 is available, this now allows a Trading Partners to map from X12 to HL7 even though no MT actually claims to do this. X12 to HL7 does not exist TP #1 TP #2 X12 HL7 cbXML to HL7 X12 to cbXML cbXML ABSTRACT TRANSLATION (c)2000 ebXML TM - Editor: Duane Nickull (duane@xmlglobal.com)
