Recently, many organizations have attempted to build hypermedia systems to expand their working areas to internet-based virtual work places. It is thus important to manage corporate hypermedia documents effectively. Metadata play a critical role for managing these documents. This paper identifies metadata roles and components to build its schema. Furthermore, a mata-information system, HyDoMis (Hyperdocument Meta-information System) is proposed by the use of this metadata schema. HyDoMis performs three functions; metadata management, search, and reporting. The metadata management function is concerned with workflow, document, and database. The system is more likely to help implement and maintain hypermedia information systems effectively.
