Transparency and Accountability Wiki Project -- ICANN Board Resolutions - Draft - 2009

Open: 21 June 2010
Closed: 26 July 2010

Explanation/Background: As part of ICANN's Transparency and Accountability Wiki Project, ICANN Staff has created searchable wiki pages to provide the public with easy-to-access information on every substantive resolution approved by ICANN's Board. In order to get initial public feedback that can serve as the basis for further improvements before full implementation, the 2009 resolutions have been loaded on the wiki. These pages are a work-in-progress.  In the interest of getting early customer input, we decided to publish these resolution pages now.  Each resolution has a wiki page that provides basic information, including when it was approved, what it's about, the status of the resulting implementation actions, and links to additional information. Each wiki page contains a comment box to allow individuals to share information about the resolution and its implementation.

Interested individuals are encouraged to use this wiki and give us feedback.  Do you like this wiki format? Have we chosen the right search categories? Is all the basic information provided in an easy-to-understand way?  Do you have suggestions for additional information on particular resolutions? Please share your thoughts to help us provide you with a more useful service. 

Is it clear to you what this comment period covers? Do you have all the information you need to respond? Please click "More information please" below to email ICANN directly.

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"""" is not an IDN."
