  • Memento achieves this by technically integrating
    the present Web and the past Web.
  • Memento’s core components:
    • The abstract notion of the state of a resource as it existed in the past: datetime as a uniform resource version indicator;
    • A bridge between present and past: link and content negotiation;
    • A bridge between past and present: link.
  • original resource and versions
  • bridge from present to past
  • bridge from past to present
  • memento
  • original resource provides no link
  • client – server interaction
  • original resource gone
  • original resource’s server gone
  • multiple archives
