OO-edi requires a paradigm shift

• Shift the focus on EDI standards to the business processes and the business practices behind them

• Decompose EDI business processes to the level of individual tasks that are more generic to the type of business

• Identify activities (i.e., transformations) and object classes that are likely candidates for standardization

Unified Process

• Development is an iterative process

• Manages requirements

• Visual modeling (Analysis & Design)

• Employs component-based architecture

• Verifies product’s quality

• Controls changes to the product

XML Recommendations

Harmonization and simplification work effort must continue to identify the core data.

UN/CEFACT should encourage W3C to develop a simple XML Repository as soon as possible to stop the proliferation of XML tag names and DTDs.

UN/CEFACT should encourage CommerceNet, the XML/EDI group, W3C, ANSI ASC X12C/TG3 and member software companies to adopt standardized tag names and DTDs for XML interchange file formats to help the SME integrate data.

Standard Web form objects need to be developed for UN Layout Key web pages. UN/CEFACT should limit its resources’ use of XML to Web forms and distributed

object messages. UN/CEFACT should NOT recast UN/EDIFACT messages into XML based on

algorithms run against EDI Directories. UN/CEFACT should encourage W3C to accelerate work on the W3C WebBroker

Note and progress it to a W3C Recommendation as soon as possible.
