RFC 2396 describes the syntax and format of a URI.

Wikipedia has a good overview over the sequence of RFC that defined and refined the URI spec.

The term RFC itself stands for Request for Comments, which sounds like it is a mere proposal, but most of them actually end up being the official industry standard.

Wikipedia: An informational RFC can be nearly anything from April 1 jokes over proprietary protocols up to widely recognized essential RFCs like Domain Name System Structure and Delegation (RFC 1591).
