Update on Root Zone Label Generation Rule Generation Panel Formation

As we approach ICANN 50, ICANN is pleased to share the steady momentum of the development on the formation of Generation Panels for developing the script proposals. These script based panels – made up of Internet community volunteers – will propose the rules that define code points, variants and additional label level constraints for the Root Zone. The latest updates on Label Generation Rule (LGR) Generation Panels will be a key topic at the ICANN meeting in London, which takes place 22-26 June 2014.

Progress to date includes:

  • The Arabic Script Generation Panel is fully formed and operational. The Panel had its second face to face meeting in June 2014, which took place in Istanbul, Turkey. Arabic script code point variants were discussed.
  • Members of the community have submitted a formal proposal to form the Chinese Generation Panel, which is currently under review.
  • There has been outreach activity in the Korean and Japanese script communities to form corresponding Generation Panels.
  • Community members involved with the Chinese-Japanese-Korean (CJK) panels have initiated coordination efforts for the Han script.
  • Members of the community are actively organizing the Neo-Brahmi Generation Panel and recruiting members. Interested parties should view the Call for Participation [PDF, 72 KB].
  • There is initial interest in forming other Generation Panels.

To learn more about these efforts, we invite you to join us in person or remotely at ICANN 50 Internationalized Domain Name (IDN) sessions:

  • IDN Variant TLDs Program session
    Wednesday, 25 June 2014 - 08:30-10:00 BST
    (http://london50.icann.org/en/schedule/wed-idn-variant-tld)
    The session will focus on updates on the IDN Variant TLD Program, and more specifically on the Root Zone LGR Project, including developments around the MSR-1, program outreach efforts, and script community updates on the LGR work.

  • IDN Root Zone LGR Generation Panels Workshop
    Wednesday, 25 June 2014 - 13:00-15:00 BST
    (http://london50.icann.org/en/schedule/wed-lgr)
    The purpose of this workshop is to foster interactions among community members, gather feedback on experiences to establish Generation Panels, and engage with Integration Panel members. Several script community representatives will present, with opportunities for questions and answers.

Speak up for your language!

ICANN continues to seek panel volunteers for following scripts: Arabic, Bengali, Chinese, Cyrillic, Devanagari, Georgian, Greek, Gujarati, Gurmukhi, Hebrew, Japanese, Korean, Latin, Sinhala, Tamil, Telugu, Thai, and other scripts. Ideal candidates will have a diverse range of interests, expertise in a variety of technical and language disciplines, and a commitment to expanding a multilingual Internet. Volunteers interested in getting involved should email ICANN at idntlds@icann.org.

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."
