A Uniform Resource Identifier (URI) is a compact sequence of characters that identifies an abstract or physical resource. The URI generic syntax, as defined in RFC 3986 (and updated by RFC 6874), is a superset of the syntax of all URI schemes. A parser of the generic URI syntax can parse any URI reference into its five major components. Once the scheme is determined, further scheme-specific parsing can be performed on the components.
