Intermedia was developed in the mid-1980 at Brown University Institute for Research in Information and Scholarship. Intermedia facilitates the creation of highly graphical microtext and complex filtering of text links. Intermedia was designed to work on personal computers more flexible than but similar to the Macintosh.
A document is created with Intermedia in a direct manipulation enviroment. Cutting and pasting can be done from one application to another. Links may be created between any two blocks. A block is defined as any material which the user selects within a document. One selection provides the source of a linkand another selection determines the destination block. A bi-ddirectiobnal link is created which can the be followed in either direction by user choice. Intermedia supports the craetion of graphics and animation. Keywords applied to links allow the user to attach one or more attributes to a link. Paths can also be defined as a sequence of links.
The keywords on links can be used to filter searches. Only links with certain attributes will subsequently be viewable. Views can be generated at different levels including the document-document level, document-block, block-block. Since views can be generated dynamically, based on filtering criteria one user can request different views of the same document in one site.
