Description of Working Group:

This working group will produce

  • A new version of RFC 3987: "Internationalized Resource Identifiers (IRIs)" using draft-duerst-iri-bis as the base
  • A new version of RFC 4395: "Guidelines and Registration Procedures for New URI Schemes"

The new version of RFC 3987 may be split into separate documents, if, in the opinion of the chair(s), it would facilitate distribution of the workload and allow more focused reviews. For example, the following breakdown has been suggested:

  • Handling of Internationalized domain names in IRIs (BCP)
  • Internationalization Considerations in IRIs (guidelines for BIDI, character ranges to avoid, special considerations) (BCP)
  • Syntax, parsing, comparison of IRIs (Standards track)

The working group starts with a relatively mature update to RFC 3987 in preparation; the primary focus of the group is to resolve conflicting uses, requirements and best practices for internationalized URLs/URIs/IRIs and various other forms, among many specifications and committees, while moving toward consistent use of IRIs among the wide range of Internet applications that use them. In particular:

  • The IRI specification(s) must (continue to) be suitable for normative reference with Web and XML standards from W3C specifications. The group should coordinate with the W3C working groups on HTML5, XML Core, and Internationalization, as well as with IETF HTTPBIS WG to ensure acceptability.
  • The IRI specification(s) should be follow best practices for domain names. The group should coordinate with the IETF IDNABIS working group and Unicode Consortium to assure acceptability.
  • Explicit review by experts on (and native speakers) of RTL languages, of the recommendations for BIDI languages, is required.

The Working Group will examine at least one and possibly more URI/IRI schemes to check that the new specification(s) are appropriate for existing schemes. The exact schemes to be reviewed will be decided by the WG.

Changes to RFC 3986 ("Uniform Resource Identifier (URI): Generic Syntax") are explicitly out of scope of this charter, and may only be considered with a charter update.

Goals and Milestones
