Generation Panel for the Arabic Script Root Zone Label Generation Rules Seated

ICANN is pleased to announce that the Generation Panel for the Arabic Script Root Zone Label Generation Rules (LGR) has been seated.

Following the Call for Generation Panels to Develop Root Zone Label Generation Rules published on 11 July 2013, the Task Force on Arabic Script Internationalized Domain Names (TF-AIDN), a community-driven initiative of the Middle East Strategy Working Group (MESWG), has developed and submitted to ICANN, on 13 January 2014, the Proposal for Generation Panel for Arabic Script Label Generation Ruleset for the Root Zone [PDF, 772 KB] (LGR Procedure). ICANN staff has reviewed the proposal including panel composition and scope, to ensure that requirements set forth in the LGR Procedure [PDF, 772 KB], and in particular the criteria set forth in the Call for Generation Panels to Develop Root Zone Label Generation Rules, are fulfilled.

ICANN would also like to use this opportunity to thank each of the members for offering their time and expertise to volunteer on the Arabic Script Generation Panel.

With composition and work plan approved, the Arabic Script Generation Panel will start its work on the label generation rules. According to the LGR Procedure [PDF, 772 KB], the starting point of any Generation Panel's work is the maximal set of code points defined by the Integration Panel as well as a set of Default Whole Label Variant Evaluation Rules. The full specification of Generation Panel's tasks can be found in the LGR Procedure [PDF, 772 KB] in particular, Section B.3 "Variant Rule Generation Procedure".

ICANN will provide a central public location workspace on the project website where Arabic Script Generation Panel composition, work plan updates, public reports, contact details, and any other relevant information will be included.

As a reminder, and to highlight the importance of script community involvement required in the development of the IDN Root Zone LGR, we would like to reiterate the Call for Generation Panels to Develop Root Zone Label Generation Rules. A successful development of the IDN Root Zone LGR depends on having Generation Panels for each script represented in the Root Zone. In the first stages of the IDN Root Zone LGR development and in addition to ongoing efforts with the Arabic script, Generation Panel formation is expected to cover following scripts: Hebrew, Chinese, Japanese, Korean, Cyrillic, Greek, Latin, Bengali, Devanagari, Gujarati, Gurmukhi, Sinhala, Tamil, Telugu, Thai, and Georgian (i.e., scripts represented in existing applications from both New gTLD and IDN ccTLD Programs).

For further information on how to form a Generation Panel or to express individual or group statements of interest for the establishment of a Generation Panel, please refer to the Call for Generation Panels to Develop Root Zone Label Generation Rules and to the additional supporting documentation provided on the Root Zone LGR Project website.

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."
