Conceptual Modeling for Educational Hyperbooks
In the last years, several modeling techniques for hypermedia systems
have been developed, which extend known domain modeling techniques from
the database and software engineering field with dedicated constructs for
specifying possibilities of navigation. The focus of these frameworks is
on providing front ends to loosely structured collections of multimedia
data. In our virtual classroom project we are creating extendible hyperbooks
for several topics in computer science. We argue that such educational
hyperbooks need a specialized conceptual modeling approach. The current
paper presents a very general modeling framework for hyperbooks, which
extends previous work by representing all aspects of a hyperbook application
in a declarative data model. This explicit, complete model of the application
hyperbook allows a reusable implementation. We introduce a fully generic
client/server architecture for displaying the hyperbook from a WWW server
to a WWW client.
