OOHS: an object-oriented hypermedia system

In this paper, we design a new hypermedia markup language using SGML and implement an object-oriented hypermedia system on top of the Postgres. Compared with the conventional systems, our hypermedia system has some advantages. First, since our hypermedia markup language is designed using SGML, the language can interchange documents in a system-independent manner and can support content-based and structure-based retrieval. Second, since we apply an object-oriented paradigm to modeling hypermedia data and links, we can inherit the properties and methods of the object-oriented model. Finally, our hypermedia system can provide database management system functions such as query processing, transaction management, storage management, security, crash recovery, and version control of structured document components as separate objects.
