This document updates the guidelines and recommendations for the definition of Uniform Resource Identifier (URI) schemes, and extends the registry and guidelines to apply when the schemes are used with Internationalized Resource Identifiers (IRIs). It also updates the process and IANA registry for URI/IRI schemes. It obsoletes RFC 4395.
