Personal Data “Use” Matrix Now Available for Public Review

This is our third in a series of blogs (read part one and part two) on the progress we have made related to data privacy and protection regulations, notably on the European Union's General Data Protection Regulation (GDPR), which will take full effect on 25 May 2018.

In our last update, we noted that an ad hoc volunteer group was formed to help us create and populate a matrix of user stories of the personal data the ICANN organization's contracted parties collect, transmit, or publish in relation to our contracts with registries and registrars. The purpose for collecting this data is to inform a legal analysis on the potential impact of the GDPR from a contractual perspective, which is an activity that we expect to begin in September.

Thanks to the hard work of this group, along with the many other community members who contributed to this effort, we now have most of this information and have published the first draft of the matrix of user stories.

We are posting the matrix for a 30-day public review period. Given the importance of ensuring the data is as complete as possible, we encourage you to review the matrix and let us know if you are aware of something that should be included. We will be updating the matrix during the review period as more data becomes available.

Gathering this information was an extensive undertaking, particularly given the aggressive schedule the group set to complete this activity. We sincerely thank everyone for their hard work and contributions to this important effort.

Following the 30-day review period, we will consolidate the data into a condensed and more easily readable format. We expect to complete this activity by early September. Once the analysis is complete, we will use this data, when appropriate, in our discussions with data protection agencies and other relevant parties. Concurrently, we will move forward with the legal analysis.

We are moving quickly through this process and we will provide you with regular updates. You can also visit the data privacy/protection page on for information that includes our blogs, details of the matrix, community initiatives, useful links and more. If you have specific questions or have content to contribute to the matrix, please reach out to us directly or email with "GDPR Matrix" in the subject line.

In closing, we want to once again express our appreciation to all of you who contributed to this data-gathering effort.


    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."
