We can now sketch the cooperation between the main architectural components of the AVANTI system within the scenario of a request for a hypermedia page. The numbers refer to those in the figure:

  1. The user requests a hypermedia page. The UI forwards this request to the HSA.
  2. The HSA fetches the requested hypermedia page and assembles an adapted page taking into account user and content-related information.
  3. The UI interprets the hypermedia page, transparently retrieves multimedia objects from the AVANTI databases via the MDI, and finally presents the requested hypermedia page to the user.
