URI - Uniform Resource Identifier

A Uniform (formerly Universal) Resource Identifier is a global identifier in the form of a string of characters. It is used to name or identify a resource, which does not necessarily have to be in digital format or available via the Internet (e.g. a human being or an abstract concept could be assigned a URI). However, URIs are the principal identifiers used in the Web environment. Whilst a URI can serve the purpose of both naming and locating, these two functions have essentially been separated into two URI subsets: Uniform Resource Locators (URLs) and Uniform Resource Names (URNs).
