The Dexter Hypertext Reference model is well suited to modelling anchor-based hypermedia systems and static hypermedia structures. But it is less clear that Dexter is adequate for systems whose linking is based on embedded references like the World Wide Web (WWW), nor for modelling the dynamic aspects of contemporary hypermedia systems like DHM and Microcosm. This paper proposes a new Dexter-based extensible objectoriented model designed to cover a broader spectrum of the features of

The model introduces two new concepts, LocationSpecifiers and ReferenceSpecifiers, which let us model links as references embedded in documents as well as links as objects in separate databases. This suggests the idea of new systems that could support both styles as one step toward integrating global networked information sources with application-bridging systems on local hosts. In addition, our model is better equipped to handle dynamic hypermedia structures. As an example, a model of Microcosm's Generic Link is given which extends that important concept in useful ways.
