Technical Study Group Engages with Community in Kobe

After a productive week of meetings with community groups at ICANN64 in Kobe, Japan, the Technical Study Group on Access to Non-Public Registration Data has charted a course toward finishing its work by mid-April. On behalf of the entire team, I'd like to thank the community for your thoughtful input, as we work to finalize our Draft Technical Model.

The Technical Study Group received feedback in Kobe and via email on a wide range of topics, including: the assumptions on which the model will be built; who will review requests for non-public registration data; and how the requested data will be stored and transferred, among other issues. We will address these issues in the revised version of the Draft Technical Model.

Some of the questions and comments are more closely related to policy choices that will guide how such a model may eventually be implemented. We urged community members who raised these issues to share these concerns with the Expedited Policy Development Process on the Temporary Specification for gTLD Registration Data team. We also plan to highlight some of those policy-related questions – which we are unable to answer – in the final version of the technical model.

The Technical Study Group continues to welcome feedback on our Draft Technical Model at Our next steps include three more virtual meetings, followed by a face-to-face meeting on 15-16 April in ICANN's Washington, DC office to review the input and finish our edits. Once complete, we will submit our final report to ICANN org President and CEO Göran Marby, who tasked our group with this project.


    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."
