Semantic Web Principles
    Evolution
    
      - The Semantic Web must allow the independent work of
      diverse communities to be combined effectively.
 
      - Support the ability to add new information without
      insisting that the old be modified.
 
      - Provide communities the ability to resolve ambiguities
      and clarify inconsistencies.
 
      - Semantic Web must be based on descriptive conventions
      that can expand as human understanding expands.
