Guidance on Designing Label Generation Rulesets Supporting Variant Labels

Overview

RFC 8228, “Guidance on Designing Label Generation Rulesets Supporting Variant Labels”, is an Informational document published in August 2017 by A. Freytag. The canonical text is published by the RFC Editor.

Abstract

Rules for validating identifier labels and alternate representations of those labels (variants) are known as Label Generation Rulesets (LGRs); they are used for the implementation of identifier systems such as Internationalized Domain Names (IDNs). This document describes ways to design LGRs to support variant labels. In designing LGRs, it is important to ensure that the label generation rules are consistent and well behaved in the presence of variants. The design decisions can then be expressed using the XML representation of LGRs that is defined in RFC 7940.
