Any changes made to documents and databases are immediately reflected in both representations. An underlying object-oriented database ensures data consistency and integrity. A client application for the Macintosh will be available soon. Similar to a Web browser, a Hyper-G client contains a component that communicates with the server plus a number of internal viewers for various document types. In Harmony, these include text, image formats, video, audio, and PostScript.
External viewers can replace the native viewers.
A central component of Harmony' s navigation aids is the session manager. It provides location feedback at all times, regardless of whether you reached an object by following a hyperlink, through a search, or by clicking on the local map. For video, Hyper-G allows the definition of a link anchor that follows an object of interest in the video. In Harmony, these may be activated both during playback and when the video is paused. Searches in the native clients, as well as from a Web or Gopher client, provide a full range of query refinement.
