For an example of such a site, visit Wikipedia at http://wikipedia.org. Wikipedia is an
encyclopedia written and maintained by the public. Anyone can write a new article or
edit an existing article, and the site is loosely organized. Articles that reference topics
discussed in other articles link to them, creating a web organization scheme. Wikipedia
has no hierarchical organization; you're expected to find the topics you're interested in
by following links or using the site's search functionality.
A web structure.
Web structures tend to be free-floating and enable visitors to wander aimlessly through
the content. Web structures are excellent for content that's intended to be meandering or
unrelated or when you want to encourage browsing. The World Wide Web itself is, of
course, a giant web structure.
In the context of a website, the environment is organized so that each page is a specific
location (and usually contains a description of that location). From that location, you can
move in several different directions, exploring the environment much in the way you
would move from room to room in a building in the real world (and getting lost just as
easily). The initial home page, for example, might look something like the one shown in
From that page, you then can explore one of the links, for example, to go into the build-
ing, which takes you to the page shown in Figure 2.15.
