Terminology

A distributed information space such as the Web consists of documents connected by links. A document may represent different types of content, it may be referenced by links, and also contain links that reference other documents within the information space. A document can therefore be referenced by a number of links each situated in a different document.

A link is embedded within a document and attached to part of latter's content by its anchor (see Figure 2) [18]. With respect to a particular link, we will define the object in which the link is embedded as the referencing document. Similarly, the object that the link points to will be defined as the referenced document.

As well as being identified with its anchor, referencing, and referenced documents, a link also has behavioural properties which become evident when it is activated and the referenced document is downloaded from the server to the user's client. This behaviour reflects the communication process which is implemented on the underlying network between the two locations.
