  1. ebXML Messaging Version 3.0 Parts 1, Part 2 and AS4

  2. Overview • Part 1: Core Specification • OASIS Standard, October 2007 • AS4 Profile • OASIS Committee Specification, April 2010 • Part 2: Advanced Features • OASIS Committee Specification December, 2010

  3. ebXML Messaging 2.0 & 3.0 • Message Header with Business Metadata • Identifies Business Partners, Transaction Semantics, Context, Agreement, Properties, Payloads • Reliable Message Delivery • At-Least-Once, At-Most-Once, In-Order delivery • Security • Digital Signature and Payload Encryption • Support for Non-Repudiation of Origin & Receipt • Leverages SOAP, MIME envelopes • XML, EDI, multimedia payloads • Multiple payloads per message • Transport Protocol Mappings for HTTP and SMTP • Composition with other eBusiness Components

  4. ebXML Messaging Version 3.0Part 1: Core Specification

  5. ebXML Messaging 2.0 & 3.0 • Message Header with Business Metadata • Identifies Business Partners, Transaction Semantics, Context, Agreement, Properties, Payloads • Reliable Message Delivery • At-Least-Once, At-Most-Once, In-Order delivery • Security • Digital Signature and Payload Encryption • Support for Non-Repudiation of Origin & Receipt • Leverages SOAP, MIME envelopes • XML, EDI, multimedia payloads • Multiple payloads per message • Transport Protocol Mappings for HTTP and SMTP • Composition with other eBusiness Components

  6. New in ebMS 3.0 Core • Further Web Services Convergence • SOAP 1.1 or SOAP 1.2 • SOAP with Attachments or MTOM • WS-Security 1.0 or 1.1 • WS-Reliability 1.1 or WS-ReliableMessaging 1.1/1.2 • Compatible with WS-I profiles • Meets new user requirements • SME endpoints, message partitioning

  7. New ebMS 3.0 Concepts & Features • Processing Modes • Parameters for capturing, expressing, sharing configuration choices, message QoS. • Message Pull Feature • Message Receiver is Polling the Message Sender • Consumer “receives” messages by pulling them from Sender • Benefit: Supports Small and Medium Size Enterprises • Occasionally connected, no fixed IP address, behind firewalls • Message Partition Channels • Messages assigned to channels • Supports priority handling

  8. AS4 Profile

  9. AS4 Profile • Message packaging governed by ebMS 3.0 • Support for both document push and pull message exchange choreographies • Message security governed by WS-Security with added support for payload compression • Support for an AS2-like business-level Non-Repudiation Receipt (MDN) • Reception Awareness – “just enough” reliable messaging (similar to AS2 and ebMS 2.0)

  10. AS4 compared to AS2 • AS4 has comparable features to AS2 including: • Document push message exchange patterns • Support for Non-Repudiation Receipts • Support for “lightweight” reliable messaging • Support for common security aspects like digital signatures, encryption, and payload compression • AS4 additionally supports the following features not available in AS2: • Document pull message exchange pattern including support for secure access to MPCs • Native support for Web Services • Support for “lightweight” client implementations

  11. ebMS3/AS4 Implementations • OASIS successful use statements (2007): • Axway, Fujitsu, NEC • Vendor implementations • Cisco, Data Applications Limited, ENEA, Flame Computing, Fujitsu, NEC • Other implementations have expressed interest in interoperability testing, but have not yet been publicly announced • Open Source: Holodeck • http://holodeck-b2b.sourceforge.net/

  12. Industry Endorsement • RosettaNet MMS • >>>>> • Japan Electronics and Information Technologies Association (JEITA) • http://ec.jeita.or.jp/eng/modules/contents01/index.php?id=3 • HL7 Version 3 Standard: Transport Specification - ebXML • http://www.hl7.org/v3ballot/html/infrastructure/transport/transport-ebxml.htm • Aerospace industry in Europe • http://www.edibasics.co.uk/edi-resources/messaging-protocols/index.htm • OASIS Energy Interoperability TC • http://www.oasis-open.org/committees/download.php/37925/energyinterop-1%200-spec-wd-12.pdf • Textile, clothing, footwear industry in Europe • eBIZ project http://www.ebiz-tcf.eu/

  13. Testing and Certification • Drummond Group is planning for the following upcoming testing events: • A week-long “virtual” BAKEOFF ideally in early December 2010 to demonstrate AS4/ebMS3 interoperability • Followed by a live BAKEOFF event at a TBD conference or expo in early 2011 • A full-matrix interoperability Certification Test in 1H2011 • Perhaps some of these testing events will be sponsored or co-sponsored by OASIS

  15. Multihop: ebMS Messaging Across Intermediaries

  16. Intermediaries

  17. Multi-hop: hub and spoke

  18. Multi-hop: connected hubs

  19. Multi-hop: hierarchical

  20. Bundling, Splitting, Joining, Compression

  21. Bundle, Split, Join, Compress • Decouple “logical” from “physical” message • Many small messages with same destination, submitted in a short interval, are more efficiently sent as a single ebMS SOAP message bundle • A (very) big message is more effectively sent as a series of smaller message fragments • Reduce data to send by using message compression • Applies to large messages and to bundles • Also covers (verbose) message headers

  22. Application Scenarios • Bundling • High volume, non real-time transactions involving small payloads • Event reporting and data synchronization • Any legacy batch application • Splitting • Messages with large payloads, or with many payloads • Compression • Payloads and message headers

  23. Features • Specification concerns interoperability only • Configuration parameters constrain what (not) to bundle, size/timing parameters, policy .. • Allows for optimization and differentiation • No impact to users: • Can be handled within MSH, no change to submission/delivery • Simple features that compose with other ebMS3 functionality • Pull, push, reliable messaging, security …

  24. Case Study • GS1 Data Synchronization: • A sample bundle containing 23 GDSN 2.7 messages; total 306K • ebMS3 eb3:UserMessage header overhead: 19K (6%) • Total after bz2 compression: 13K, i.e. 4% • Other case studies • eCom 2.6 order (11 docs, 83K), UBL 2.0 (13 docs, 11.8K), bz2/zlib compression: worst case 8% • Comparison with payload compression: • Best case 14%; worst case 25% • Use bundle, split and compress to “optimize” message sizes

  25. Summary

  26. ebMS 3.0 (and AS4) • ebMS 3.0 Core Specification • WS-* based • WS-I profiles compliant • Functional superset of ebMS 2.0 • Important extensions for Small and Medium-Size businesses • AS4 • Profile of Core Specification • Functional superset of AS2 • Adds payload compression, Non-Repudiation of Receipt, Reception Awareness

  27. Part 2: Advanced Features • Intermediaries • Enable SME-to-SME message exchange • Bundling • Support efficient high-volume message exchange • Split, join, compress • Support efficient transfer of very large messages (and message bundles) • Variants in MEP Execution • Better Pull and Sync replies

  28. ebMS 3.0 Parts 1, 2 and AS4 • B2B protocol with the broadest coverage of user deployment scenarios • Push, Pull and Synchronous exchanges • From light-weight clients to high-end B2B gateways • Point-to-point exchange and multi-hop exchanges • From occasional exchanges to very high volume exchanges • From small message exchanges to very large message exchanges • Web Services based functionality that: • Is not in any other WS-* specification • Only exists in (industry) niche B2B or MFT protocols • Is handled (redundantly) at the application layer
