• Application/domain agnostic structure
• Comprehensive to express wide variety of business
  models
• Application to all phases of life cycle
• Extensible to allow adaptability and minimize
  future cost of change
• Ease of implementation and deployment

Why OASIS?

• Standards are created under an open, democratic,
  vendor-neutral process
• Any interested parties may participate, comment
• No one organization can dictate the standard
• Ensures that standards meet everyones needs, not
  just largest players
• Open to all interested parties..Individual
  Memberships
• All discussion open to public comment
• One organization/One vote
• Resulting work is guaranteed to be representative
  of the industry as a whole, not just any one
  vendors view
