                       Principles which shape
            Market-Driven Data Strategy
 Focus on Common implementable Components
 Seek commonality mainly within Communities of
  Interest (COIs)
 Develop common representations for 20% of
  data to satisfy 80% requirements
 Create market environment to exploit survival of
  “fit” data representations in various domains
 PMs and their engineering staffs are primary
  marketplace players
 Provide visibility for existing implementations thru
  Data Component registry with low barriers to
               DII-COE XML Registry Objectives
   Technical Requirement
          Ensure uniqueness of in-use tags, schemas
           etc. (like network port assignments)

   Management Objectives
          Visibility
              Identify and converge synonyms within CM
               process on cost-benefit, prioritization basis
              Encourage Re-use
          Information Interoperability
            Purpose is uniqueness and visibility, not
               standardization through mandate!                16

XML Tag Registration Requirement
 Configuration Review Control Board (CRCB) directs (via I&RTS 4.0)
  DII-COE Developers using XML for public interfaces to:
      Consult XML Registry before creating new Tags and reuse existing
       XML where practical
      Indicate planned use of Registered Tags by formally subscribing to
      Submit (where required)
         additional XML tags (and amplifying information) or
         recommended modifications to existing tags

Management of Namespaces
 With CRCB concurrence, DII-COE Chief Engineer:
      Charters selected agents to manage XML Namespaces
           Example: USMTF Program AO to manage XML-MTF tags
