New gTLD Program: Technical Resources for Trademark Clearinghouse Available to Prospective New gTLD Registry Operators

In response to community request, ICANN is establishing an open mailing list to further refine and complete the technical specification of the interface between the new gTLD Registries and the Trademark Clearinghouse.

One way to protect property rights, and the interests of registrants, in the New gTLD Program is the establishment of a Trademark Clearinghouse. The Trademark Clearinghouse is being designed to increase protections and reduce costs for trademark holders and start-up registries alike. Given that new gTLD registry operators will need to establish systems to support the required Sunrise and Trademark Claims services, ICANN is inviting participation on a technically-focused mailing list.

The mailing list is open to any interested participants. The scope of the discussion is limited to refining the technical details of the Registry-Clearinghouse interface. It is expected that the discussion will be highly specialized and will be most relevant to those involved in implementing the Sunrise and Claims processes on the registry side. According to the established project plan, the model specification will need to be in place by 15 August 2012.

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."
