SW Principles 3: Web of Trust
    
      - All statements on the Web occur in some context.
- Applications need this context in order to evaluate the
      trustworthiness of the statements.
- The machinery of the SW does not assert that all
      statements found on the Web are "true".
- Truth - or more pragmatically, trustworthiness - is
      evaluated by each application that processes the information
      on the Web.
