Recently, many organizations have attempted to build hypermedia systems to expand their working areas into Internet-based virtual workplaces. Thus, it is important to manage corporate hypermedia documents effectively. Metadata plays a critical role for managing these documents. This paper identifies metadata roles and components to build a metadata schema. Furthermore, a meta-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, documents, and databases. The system is more likely to help implement and maintain hypermedia information systems effectively.
