Originating Organization: ICANN Policy Development Department
Purpose: ICANN staff is seeking comments on the draft Final Report [PDF, 437 KB] of the Internationalized Registration Data Working Group (IRD-WG).
Current Status: On 26 June 2009 the Board of Directors of the Internet Corporate for Assigned Names and Numbers (ICANN) approved a resolution (2009.06.26.18: http://www.icann.org/en/minutes/resolutions-26jun09.htm#6) requesting that the Generic Names Supporting Organization (GNSO) and the Security and Stability Advisory Committee (SSAC), in consultation with staff, convene an Internationalized Registration Data Working Group (IRD-WG) comprised of individuals with knowledge, expertise, and experience in these areas to study the feasibility and suitability of introducing display specifications to deal with the internationalization of registration data. Subsequently, the SSAC and the GNSO formed the IRD-WG. The IRD-WG produced an Interim Report requesting community input on several questions relating to possible models for internationalizing Domain Name Registration Data. See http://gnso.icann.org/issues/ird/ird-wg-final-report-15nov10-en.pdf [PDF, 686 KB]. Now the IRD-WG has provided a draft Final Report in response to the Board's request. ICANN staff is seeking comments on this draft Final Report [PDF, 437 KB].
Next Steps: Following the close of this comment period, the IRD-WG, will discuss and consider all of the comments received and prepare a Final Report, which will then be considered by both chartering organizations, the SSAC and the GNSO Council.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
