Call for Subject Matter Experts for the IDN Root Zone LGR Integration Panel and Advisors to All Panels

Today, ICANN's IDN Variant TLD Program moves forward with initiating the implementation of the IDN Root Zone LGR Procedure by publishing the Call for Subject Matter Experts for the IDN Root Zone LGR Integration Panel [PDF, 169 KB] and Call for Advisors to the IDN Root Zone LGR Panels [PDF, 164 KB].

The IDN Root Zone LGR implementation project will undertake work to develop the rules that identify the valid repertoire of code points for IDN TLDs, as well as the rules for identifying and possibly delegating any IDN variant TLDs. The work is carried out as specified in the "Procedure to Develop and Maintain the Label Generation Rules for the Root Zone in Respect of IDNA Labels" [PDF, 1.39 MB] (Procedure) and involves an Integration Panel, (to be staffed by paid experts), a set of Advisors to all Panels (formed of paid consultants, volunteers, or ICANN staff), and a set of Generation Panels (consisting of volunteers). The latter are subject to a separate call.

Successful development of the IDN Root Zone LGR depends on having Integration Panel members with the right skills to perform the substantive work. Therefore ICANN is soliciting the participation of subject matter experts to serve on the Integration Panel and advisors to the Integration and Generation Panels.

The Integration Panel will be comprised of a small number of technical experts in the following areas: DNS, IDNA, Unicode, and linguistics. The Call for Subject Matter Experts for the IDN Root Zone LGR Integration Panel [PDF, 169 KB] describes the details of expertise needed, as well as the expert selection process. The Call for Advisors to the IDN Root Zone LGR Panels [PDF, 164 KB] describes the desired expertise for advisors and their selection process. Interested experts are invited to submit their CV and an expression of interest statement demonstrating how they meet the qualifications for one or other of the subject matter or advisor expertise areas. Expressions of interest should be sent to idnvarianttlds@icann.org no later than 27 June 2013.

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."
