URI Design and Ownership

Overview

RFC 8820, “URI Design and Ownership”, is a Best Current Practice document published in June 2020 by M. Nottingham. It updates RFC 3986. It obsoletes RFC 7320. The canonical text is published by the RFC Editor.

Abstract

Section 1.1.1 of RFC 3986 defines URI syntax as "a federated and extensible naming system wherein each scheme's specification may further restrict the syntax and semantics of identifiers using that scheme." In other words, the structure of a URI is defined by its scheme. While it is common for schemes to further delegate their substructure to the URI's owner, publishing independent standards that mandate particular forms of substructure in URIs is often problematic.

This document provides guidance on the specification of URI substructure in standards.

This document obsoletes RFC 7320 and updates RFC 3986.

Abstract as published in the RFC, via rfc-editor.org.

What “Best Current Practice” means
