URI (Definition)

A Uniform Resource Identifier.

This is another name for a URL. Some commentators argue that a URI is different to a URL. One identifies the target while the other locates it. There may be several copies at different URLs but perhaps they would all be instances of the same URI.

A URI is composed like this (according to the ECMA standard):

scheme:first/second;third?fourth
