The Dexer Hypertext Reference Model
Excerpt:
The Dexter Hypertext Reference Model is an attempt to capture, both
formally and informally, the important abstractions found in a wide
range of existing and future hypertext systems.' The goal of the model
is to provide a principled basis for comparing systems as well as for
developing interchange and interoperability standards. The model is
divided into three Iayers. The storage layer describes the network of nodes
and Iinks that is the essence of hypertext. The run-time layer describes
mechanisms supporting the user's interaction with the hypertext. The
within-component layer covers the content and structures within hypertext nodes. The focus of the model is on the storage layer and the mechanisms of anchoring and presentation specification that form the
interfaces between the storage and the storage layer and the within
component and run-time layers, respectively.
