Web Developer Resource Index: URI

The Uniform Resource Identifier is the fundamental and most important element in the design of the WWW. It is an address that uniquely identifies any resource in the global information space. Examples include the ubiquitous HTML document, an image, or some other media source such as a music file.

The URI to this page is made up of three basic parts:

More complicated URIs may include query string or GET variables, which begin with a question mark (?) character after the path, followed by name=value pairs separated by ampersands (&).

Sometimes called in-page links, fragment identifiers are also located at the end of a URI, with a hash or pound (#) character followed by the id value. The Navigation menu on this page uses fragment identifier links to move you to specific locations within this and other pages.

• 2.Well Designed URLs are Beautiful!

  Another article on designing your site, and the URLs used to navigate it. Well thought out, with many good points that I seemed to have instinctively adhered to here (and few people do): point number six: Well Designed URLs are Readable and Heirarchical. [1654]

• 3.Designing URIs

  Although you may have never thought of it as "design" (I do), it is important to carefully think about site structure and how URIs to different resources are related. Failure to do so can come back and haunt you. I speak from experience. [1249]
