Abstract

This SRFI proposes a programming interface for working with RFC 3986 universal resource identifiers (URIs), as well as RFC 3987's generalisation to internationalised resource identifiers (IRIs). This document defines record types, normalisation procedures, and conversion between URIs and IRIs. Additionally, we contribute a test suite to specify the behaviour of normalisation with respect to relative references, which has in the past been a source of divergence between implementations.
