Technical Study Group Publishes Charter

Tsg charter 1472x838 21dec18 en

Since starting our work in December, the Technical Study Group on Access to Non-Public Registration Data has finalized its charter and set a course for delivering a draft specification for community input in time for the ICANN64 Public Meeting in March 2019. We invite the ICANN community to read the charter here [PDF, 47 KB].

As previously described, this group is made of 10 invited members with expertise in the Registration Data Access Protocol (RDAP), distributed authentication/authorization technologies, systems architecture, design-thinking, and other relevant topics. We are focused on exploring technical solutions for authenticating, authorizing, and providing access to non-public registration data for third parties with a legitimate interest, where ICANN would determine whether a third party’s query ought to be approved to proceed. The charter outlines assumptions and key questions the group plans to tackle as it works to produce a draft specification.

The group will resume its work in the new year and will hold its first face-to-face meeting from 14-15 January 2019 in Washington, D.C. We will continue to keep you posted as we make progress in our discussions. You can follow our mailing list here; recordings of meetings and other materials are available here.


    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."
