Board Review – Draft Final Working Group Report

Open: 5 October 09
Closed: 4 November 09 Extended to 22 November 09

Explanation/Background: ICANN appointed the Boston Consulting Group/Colin Carter & Associates to perform the external review of its Board of Directors; their review report was presented during a public workshop at the ICANN meeting in Cairo and a public comment period followed.

The Board review WG, considering the Independent Reviewer's final report, Board input, and comments from stakeholders and the public, issued an Interim Report for consultation with the Community [PDF, 124 KB], which was presented at the ICANN meeting in Mexico City. During the following public comment period further inputs were received from interested parties.

A second interim report [PDF, 130 KB] was then issued and presented at the ICANN meeting in Sydney. Comments received during its presentation and during the following public comments phase helped the Board review WG to conclude its analysis of the few issues that were still outstanding; the WG releases now its draft final report [PDF, 132 KB], which will be presented at the Seoul meeting. Community is invited to participate to this final round of consultation before the finalization of the report for Board action.

Staff member responsible: Marco Lorenzoni

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."
