Abstract

This article describes a simple method for creating and maintaining hypermedia link markers. In general, hypermedia link markers must be explicitly created and connected by the user. If a linked-to document has a more recent version (e.g., a new encyclopedia edition), all link markers pointing to the older version are obsolete and must be recreated. The number of link markers that would have to be changed could be very large. This makes it difficult to maintain hypermedia links.

Classes of Hypermedia Link Markers

       This article describes a simple method for creating and
maintaining hypermedia link markers.  In general, hypermedia link
markers must be explicitly created and connected by the user.  If a
linked-to document has a more recent version (e.g., a new
encyclopedia edition), all link markers pointing to the older version
are obsolete and must be recreated.  The number of link markers that
would have to be changed could be very large.  This makes it
difficult to maintain hypermedia links.

      A method to define a group of link markers as a class is
needed.  Being a member of the class automatically connects a link
marker to the other link markers in the class.  When creating a link
marker in a class, the user does not have to connect it to other link
markers in the usual, manual way.  The user would have the ability
during the creation of a link marker to specify the class of the
link.  This class could be already created or created at a later time
(the user would be notified if the class has not been created yet).
Later, the links implied by the class could be adjusted without any
changes to the original link marker.

      An on-line function for creating classes of hypermedia link
markers is needed.  To create a new class, the user enters the class
name in an entry field and then presses an "Add" button.  The user
will then be given an opportunity to specify the links associated
with the class. There are two ways to specify the links for a class.
      1.   The user can open documents and manually create the link
markers, or he can use existing link markers that were created
earlier.
      2.   The user can specify one or more existing classes to be
used as a model for creating the new class. He can view a list of
all the already defined classes and select the model class from the
list. The user is given the opportunity to include or exclude links
associated with the existing class.

      Both methods of associating links with the new class can be
used together.  For example, a user defining a new class could select
an existing class, exclude some of its links, and then define some
new links.

      Classes of hypermedia link markers provide a simple way to
create and maintain links between documents.  However, there
