RDAP Transformation of Contact Information

Generic TLDs (gTLDs) Domain Name Registries and Registrars operating according to an agreement with the Internet Corporation for Assigned Names and Numbers (ICANN), are required to follow ICANN Consensus Policies. On 2015/09/28, the ICANN Board adopted the GNSO Council Policy Recommendations concerning the translation and transliteration of contact information as presented in the "Final Report on the Translation and Transliteration of Contact Information Policy Development Process" (T&T Report, see ). The T&T Report recommends: Contact information that has been transformed (i.e. transliteration or translated) must be marked as such and their source(s) indicated. This specification is intended to be used by gTLD Domain Name Registries and Registrars in order to support this recommendation.

A server that conforms to this specification MUST include the string literal "rdap_transformation_of_contact_information" in the "rdapConformance" member of the topmost JSON object of all responses provided by the server. An example of a rdapConformance data structure including this extension:

A transformation object class represents the transformation (i.e. transliteration or translation) of an entity object. The transformation object class uses jCard to represent contact information, such as postal addresses, email addresses, phone numbers and names of organizations and individuals. Many of the types of information that can be represented with jCard have no use in RDAP, such as birthdays, anniversaries, and gender. The transformation object class contains the following members: objectClassName -- the string "transformation". vcardArray -- a jCard with the entity's contact information. The language property MUST be included in the jCard object in case of a translation in order to indicate the language that the contact information was translated to. sourceOfTransformation -- a string containing the source of the transformation. The possible values of sourceOfTransformation are: registry, registrar or reseller. typeOfTransformation -- a string containing the type of the transformation. The possible values of typeOfTransformation are: translation or transliteration. An OPTIONAL transliterationStandard -- a string containing the standard (e.g. ISO 9, ISO 7098, etc.) used for the transliteration. This element MUST be present if typeOfTransformation is transliteration.

The transformations object is an array of transformation objects (defined in ) included in an entity object. If a transformations object is included, the parent entity object MUST show the contact information as originally inputted by the user. The following is an example of a JSON domain object, that includes a transformations object, representing a forward DNS delegation point that might be served by a DNR.
