Chapter 6. Links and Webs > Relationships

6.7. Relationships

Very few documents stand alone. Instead, a document is usually part of a collection of documents, each connected by one or several of the hypertext strands we describe in this chapter. One document may be a part of several collections, linking to some documents and being linked to by others. Readers move between the document families as they follow the links that interest them.

You establish an explicit relationship between two documents when you link them. Conscientious authors use the rel attribute of the <a> tag to indicate the nature of the link. In addition, two other tags may be used within a document to further clarify the location and relationship of a document within a document family. These tags, <base> and <link>, are placed within the body of the <head> tag. Section 3.7.1
