VIEWING DEXTER WITH OPEN EYES

Many people think of hypermedia as a framework for organizing or struc turing information Others view hypermedia more from a behavioral or pr ocess-oriented perspective. It is not surprising, therefore, that exis ting models for hypermedia tend to fall into three main categories: 1) data models, concerned with the data structures that implement interc onnected information; 2) process models, concerned with the interactio ns that occur between a user and a hypermedia system, or the semantics of linking and browsing; and 3) combination models, which address var ious aspects of structure and behavior. Dexter is a combination model that captures the essentials of the dynamic, interactional aspects of hypermedia systems in the run-time layer, but focuses most of its atte ntion on the data modeling aspects of hypermedia in the storage layer. As such, the Dexter model provides a valuable reference for developin g interchange and interoperability standard, through which hypermedia can be shared.
