Techniques Methodologies Work Groupings Mission

• To research and identify techniques and
  methodologies which could be utilized by
  UN/CEFACT and its working groups to enhance the
  process by which its deliverables are produced
  and integrated.

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 products 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.

  analysis e.g. through business modelling
• Lack of an effective global repository of
  standardised data entities
