Abstract:

Developing an effective framework for a large collection of linked documents involves: creating an efficient hierarchy of information; mapping task flows through the information hierarchy; determining the best depth for the information space; and creating nodes of appropriate length. These four tasks should be undertaken in order. Each one depends on the outcomes of preceding tasks. Because these elements are interdependent, however, several good solutions to the first two should be developed so that problems with site depth and node length can be addressed.
