1 XML/EDI Overview West Chester Electronic Commerce Resource Center (ECRC)

2 Topics u XML Background u XML/EDI u XML/EDI Initiatives u XML/EDI Tools u XML/EDI Vision u Next Steps

3 BackgroundBackground u Proprietary Markup Languages ä Word Processors u Standard Generalized Markup Language (SGML) ä ISO defines a generic document definition and data markup language ä Separate structure & content u Hypertext Markup Language (HTML) ä Application of SGML (HTML DTD) ä Predefined set of tags ä Defines the format of a document

4 Background Background (cont’d) u Extensible Markup Language (XML) ä Describes a class of data objects called XML documents which are stored on computers & partially describes the behavior of programs which process these objects ä Restricted Form of SGML – 80% of functionality – 20% of complexity ä XML provides a mechanism to impose constraints on the storage layout & logical structure of documents

5 Why Use XML? u Create your own tags to describe content u Easy to create structured documents u To describe, deliver, & exchange structured data between applications u Hardware/software independent u More powerful than HTML u Less complicated than SGML Background

6 XML Benefits u More meaningful searches u Separation of content and format u Development of flexible web applications u Open standards u Flexible format for different use ä Wire format for web delivery ä Transfer format for sharing data ä Persistent data format for disk storage Background

7 XML Components u XML family of standards ä XML ä XML Link Language (XLL) ä XML Stylesheet Language (XSL) ä Document Object Model (DOM) ä XML Query Language (XML-QL/XQL) ä Namespaces ä Document Content Description (DCD) ä XML Repositories

8 Background XML Usage u Presentation-Oriented Publishing (POP) ä POP documents are chiefly written by humans for other humans to read ä Browser - Browser u Message-Oriented Middleware ä MOM documents are documents mainly generated from computer systems for use by other computer systems ä Application to Application ä Application to Human/Human to Application

9 Background XML Documents u Consist of character data and markup u Allowed markup ä Elements ä Entity references ä Comments ä Processing instructions ä Marked sections ä Document type declarations

10 Prolog Document Type Declaration Root Element Element Epilog Background XML Document Structure

11 Two Classes of XML Documents Well Formed XML Documents Valid XML Documents Background

13 What’s on the Horizon for XML u Intelligent agents u Structured records u Objects with methods and data u Metacontent for Web sites u Query results u Graphical user interface u Persistent storage formats u Online procedures documentation u Interactive parts catalogs u Electronic service manuals u Electronic Data Interchange

14 XML/EDI XML/EDI Goals u To deliver unambiguous and durable business transactions via electronic means u Utilize existing systems and processes u Protect investment in traditional EC/EDI u Provide a migration path to next generation XML/EDI systems u Use existing business processes as implemented u Facilitate direct interoperation in an open environment

15 XML/EDI The Five Technologies 0f XML/EDI

16 XML/EDI Layers of an XML/EDI System

17 XML/EDI Future Based on XML/EDI

18 XML/EDI Typical EDI Scenario Request for Quote (840) Response to RFQ (843) Purchase Order (850) P.O. Acknowledgment (855) Purchase Order Change (860) P.O. Change Acknowledgment (865) Invoice (810)/Advance Ship Notice (856) FRT Bill (210) Receiving Advice (861) Payment Order/Remittance Advice (820) Electronic Funds Transfer Your Customer Purchasing Receiving Financial You Sales Order Entry Shipping Financial Technical Specifications (841)

19 XML/EDI EDI Processes u Data Entry/Data Collection u Application Extract u Outbound EDI Processing u Communications Processing u Inbound EDI Processing u Application Import u Error Handling

20 XML/EDI XML/EDI Scenario u Company A extracts PO data from purchasing system ä UDF ä XML Document(s)/XML Objects u Map extracted PO data to XML/EDI or EDI format ä Validate XML/EDI against repository DTD/DCD IC u Transmit XML/EDI to Company B ä Via VAN ä Via Internet – http, ftp, smtp

21 XML/EDI XML/EDI Scenario (cont’d) u Company B receives/retrieves XML/EDI PO u Access repository ä Appropriate XSL stylesheet(s) for processing ä DTD ä DCD u Process XML/EDI PO ä Import into order entry system ä Print order

22 XML/EDI Why Use XML for EDI? u XML bridges the gap between traditional EDI & Web-based applications u Most of software industry has embraced XML ä Microsoft, IBM, Netscape, Oracle, SAP, etc. u XML could make EC/EDI more available to SMEs & other non-traditional EDI users

23 XML/EDI Problems using XML for EDI u Data Typing ä Currently XML has no facility to show data types u Exposed Semantics ä Currently XML has no method to show relationships between data elements & other structures u Repeat Counts ä Currently XML has no method to designate segment or loop counts u Minimum/Maximum Lengths ä Currently XML has no method to specify minimum and maximum lengths
