Navigation in Hypertext
Two important aspects of the structure of hyperdocuments are hierarchies and metrics.
Hierarchies are used to view a hyperdocument somewhat like a book with chapters, sections, subsections, etc. The hierarchical structure of a hyperdocument can be compared to the grid structure of a city, while the exceptions to the hierarchy: the cross-reference links, are the disturbing factors like Broadway is in Manhattan. If there are few cross-reference links, the user is not likely to get lost, as hierarchical document structures are common and resemble a book structure [De].
Metrics is what used to measure how well-connected a hyperdocument is, and how "linear" its structure is [De].
