This paper presents HOED, a distributed hypermedia client-server system for educational resources. The aim of HOED is to provide a library facility for hyperdocuments that is accessible via the world wide web. Its main application domain is education. The HOED database not only holds the educational resources themselves, but also data describing characteristics of these resources. Distinctive features of the HOED server are the separation of data regarding content (nodes) and structure (links), and use of a database management system (DBMS) rather than files for data management. The use of the HOED infrastructure for the development of private study modules on basic computer science topics and for reuse of courseware components is explained. Finally, HOED is briefly compared to related research. (Contains 11 references.) (Author)
