Sachtitel: HarAdmin; a graphical tool for Hyper-G server administration

Abstract
This thesis gives a short overview of information systems available on the Internet and a detailed description of Hyper-G, the first second generation hypermedia information system. The biggest problem of distributed information systems is disorientation. Because of the huge amount of information available on the Internet the user has difficulty to gain an overview, to know how much information exists to a certain topic, etc. Hyper-G has navigational, structuring, and search facilities to help cope with this problem. Two particular features are Hyper-G's user accounts and its hierarchical scheme of user groups, which are used to grant or deny access to specific parts of the information space. Hgadmin, a VT100 terminal and HarAdmin, a graphical X-Windows based tool for user and group administration are explained in detail in this thesis. HarAdmin is based on the Hyper-G Client/Server Protocol and on hgadmin. It provides functionality for browsing through the user-group hierarchy, displays allexisting users and groups of the current Hyper-G server, and makes it easy to create, delete, and manipulate user accounts and user groups.
