ICANN Meetings in Accra, Ghana – 10-14 March 2002 | Preliminary Announcement

ICANN's next round of meetings will be held 10-14 March 2002 in Accra, Ghana. The meetings are free to all attendees, and open to any interested person. ICANN encourages broad participation in its bottom-up consensus-development process. The meetings will be held in the brand new convention center close by Accra's modern hotels.

In addition to ICANN's normal meetings, consideration is being given to devoting part of the meeting to a special topic. More details will be announced later.

Information relating to the meeting is posted on the ICANN web site. Please also check the local host's web site (mirrored here) for information on hotels and air transportation. Air transportation should be booked early. Pre-registration will be available soon.

Because the meeting is in a tropical climate, protection against yellow fever is required and protection against malaria is recommended. Please also consult your local health service for advisory information. Protection must normally be obtained at least one month prior to the date of departure. Business visas are also required for visitors from many countries so attendees should check with their local Ghanaian embassy or consulate.

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."
