AN OBJECT-ORIENTED HYPERMEDIA SYSTEM BASED ON THE DEXTER REFERENCE MODEL AND THE MHEG STANDARD

In this paper, we describe the design and implementation of a hypermed ia system that has the following characteristics. First, being designe d according to the Dexter hypertext reference model, it has a layered architecture and thus maintains commonality with other hypermedia syst ems based on the Dexter model. Second, being designed based on the MHE G standard, it has data structures that are inherently suitable for da ta interchange and synchronization. Third, adopting the MIME protocol, it provides multimedia mail services. Finally, being built on top of an object-oriented DBMS, it makes it easy to represent Dexter and MHEG models and also provides efficient storage and search capabilities. T he contribution of this paper is combining these characteristics to bu ild an integrated hypermedia system reflecting reference architectures and international standard efforts.
