Abstract

Web viewers require environmental awareness: 1) Hypertext links can number in the hundreds on a single workstation. A given set of these links may be called a "web". A tool to graphically view this set, called a web viewer, is a valuable time-saver for the hypertext user or author. While viewing a web it makes little sense to have to open applications or make changes. Direct manipulation of links from within the web viewer makes changes much easier. (See Fig. 1 for an example of a primitive web viewer. Real applications have been replaced by numbered nodes.) Display of the web and direct manipulation of links require "environmental awareness". Environmental awareness means knowledge about the system as a whole, what applications have windows open as well as what applications have links to/from other applications.

Link Web Class Hierarchy

       Web viewers require environmental awareness:
      1)   Hypertext links can number in the hundreds on a single
workstation.  A  given set of these links may be called a "web".  A
tool to graphically view this set, called a web viewer, is a valuable
time-saver for the hypertext user or author. While viewing a web it
makes little sense to have to open applications or make changes.
Direct manipulation of links from within the web viewer makes changes
much easier.  (See Fig. 1 for an example of a primitive web viewer.
Real applications have been replaced by numbered nodes.)  Display of
the web and direct manipulation of links require "environmental
awareness".  Environmental awareness means knowledge about the system
as a whole, what applications have windows open as well as what
applications have links to/from other applications.  A window
associated with a particular application may need to be notified to
update the link markers which it contains, as the result of a change
made in the web viewer.
      2)   The web viewer should provide the ability to exchange one
web for another.  This kind of wholesale alteration of the system
again requires the knowledge mentioned above.  It would be nice to
inherit this functional knowledge from the environment, rather than
to require each application to manage the web of links that currently
apply to itself.

      The solution is to implement the web function by integrating...
