B2B formats – history…
• EDI (Electronic Data Interchange)
• What is it?• Exchange of any data electronically• Not dependent of format or transport
• Where did it come from?• Depends on who you ask…
• What is it now?• X12• EDIFACT• ebXML• RosettaNet• xCBL• And more…
B2B, a brief description
• Classification?• External messages• Message standards• ”Security packaging”• Trading partner management
• Typical implementation?• Various ”platforms”, servers and adapters• Many formats, specifications and no documentation• In short, A MESS!
What can we do?
• Documentation!• TPP – Trading Partner Profile• TPA – Trading Partner Agreement
• Consolidation of servers/protocols
• Extend SOA to include B2B
• Break pure B2B formats in B2B layer
• Work with external partners
• Add security!
B2B formats – X12• ASC X12 (Accredited Standards Committee)• a.k.a. ANSI X12• Created 1979
• Numbered messages (transaction sets), e.g. 850 (Purchase Order), 810 (Invoice)• Using “version” and “release”, e.g. Version 4 Release 1 (typed as: 004010)
ISA*00* *00* *08*9251750000 *08*1234567890 *030627*1304*U*00401*000001403*0*P*>~GS*PO*8019721193*1234567890*20030627*1304*1403*X*004010~ST*850*01403001~BEG*00*SA*548177**20030627~REF*AN*547794~PER*BD*JOHN JONES*TE*5552225555~…….SE*30*01403001~GE*1*1403~IEA*1*000001403~
B2B formats – X12• ANSI X12 or ASC X12
• ANSI - American National Standards Institute (ANSI)• ASC - Accredited Standards Committee• CICA (or Context Inspired Component Architecture)
• B2B processes as ”reusable” XML entities• X12 CICA Metadata Interchange Format (CICA-MIF)
• bi-directional data exchange• RDF (Resource Description Framework) and OWL, a Web Ontology Language
• RDF is a framework for describing resources on the web, e.g. properties for items, content and time schedules
• Ontology is about the exact description of things and their relationships.• Use as a EDI Service Registry and Repository

• EDIFACT• Approved by United Nations 1986• ISO standard ISO-9735• Named messages (6 letters), e.g. ORDERS,
INVOIC• Two releases yearly: D[YY].A and D[YY].B
• E.g. D96.A (NB! S-releases exist)
B2B formats - EDIFACT• Other common standards:
• ODETTE, European car industry• TRADACOMS, retail industry• HIPAA, US Health Care Claim Transaction set

B2B protocols• Common and recommended:• HTTP/S• FTP/S• sFTP (SSH)• VAN (Value Added Network)
• Common:• VPN• X.25
• Less common and NOT recommended:• X.400 (Yes, it is still alive)• SMTP• USB Stick, print-outs or CD
B2B protocols• Applicability Statement• AS1 - Email• AS2 - HTTP/S• AS3 - FTP/S & sFTP• AS4 – SOAP/WS (TBD)
• Based on S/MIME• Supports digital certificates and encryption• Messages may request a Message
Disposition Notification (MDN)• Non-repudiation achieved through digest

EDI Transmission• What is it?
• Getting the data across from one Trading Partner to the other• Trading Partners are referred to as ”Internal” or ”External”• Transmission is the “sending” of EDI• Transaction is what is being sent
• How to do it?
• VAN Services• Packages, protocol bridging, adding security (hopefully), transformation• a.k.a. ”Clearinghouse”
• Use a B2B gateway product, e.g. BizTalk
EDI Transmission• EDI Acknowledgments
• X12• Technical Acknowledgment
• a.k.a. “TA”• Is sent if message is received and understood
• Functional Acknowledgment• a.k.a. “997” or “FA”• Function stipulated in TPA (remember that “Trading Partner Agreement” document?)• Requires validation of the complete message and/or group• Accepted or Rejected status report on the compliance with the “standard”(*)
(*) “Standard” = In EDI you have as many standards as there are senders
EDI Transmission• EDI Acknowledgments
• EDIFACT• Technical Acknowledgment (well, sort of…)
• a.k.a. “CONTRL”• Is sent if message is received and understood
• Functional Acknowledgment• a.k.a. “CONTRL”• Function stipulated in TPA • Requires validation of the complete message and/or group• Accepted or Rejected status report on the compliance with the “standard”(*)
(*) “Standard” = In EDI you have as many standards as there are senders
EDI Transmission• EDI Acknowledgments
• Synchronous vs. Asynchronous
• Can be sent either way• X12 more commonly use synchronous• EDIFACT pretty much never use synchronous
• AS2 and Acknowledgments
• MDN is sent either Synchronous or Asynchronous• I.e. any EDI Acknowledgments will be sent Asynchronous
EDI Transmission• EDI batching
• Batching is a processing of a bunch of messages
• Still very common!
• History of using FTP transfers
• Saves money if using a VAN service
• It’s the way it has always been done…
EDI in the future…• XML Based (of course)
• ebXML• ebMS - ebXML Messaging Services
• SOAP/WS based icl. Processes and receipts• ISO 15000• Collaborative Partner Profile Agreement, CPA Documents
• xCBL (Common Business Library)• Open source, EDI based
• RosettaNet• Open consortium• Mostly Telecom
• And of course EDIFACT and X12!
