Relevant Reading Material

The material listed below is provided for preparation for the various IDN sessions and in order to provide a general overview. Additionally it is recommended to review previously held IDN workshops. An overview of these can be found at: http://icann.org/topics/idn/meetings.htm

IDNA Protocol Revision

The IDNA protocol was published in 2003 reflected in RFCs 3490, 3491, and 3492. The protocol was based on the Unicode version 3.2 and is currently under revision, both in terms of the functionality as based on implementation experience, and also to upgrade it to be based on the current version of Unicode (5.0).

In this connection RFC4690 (September 2006) describes issues surrounding the continued development of IDNs and in particular IDNA revisions opportunities and difficulties, such as for example:

  • revision to support Unicode 5.0
  • language specific character issues
  • issues related to use of multiple scripts for one language
  • bi-directional cases
  • visually confusable character issues

ICANN issues discussed includes: Dispute management, Whois management, and Registry policies.

In response to some of the issues discussed in the RFC4690 ad hoc design team recently published three internet drafts through the IETF editor, providing suggested solutions. The three internet drafts can be found as follows:

http://www.ietf.org/internet-drafts/draft-klensin-idnabis-issues-00.txt
http://www.ietf.org/internet-drafts/draft-alvestrand-idna-bidi-00.txt
http://www.ietf.org/internet-drafts/draft-faltstrom-idnabis-tables-01.txt

IDN Guidelines

The first version of the IDN Guidelines was created in 2003 in conjunction with the IDNA protocol as mentioned above.

Following implementation experience a working group was formed to revise the guidelines. The group consist of IDN TLD representatives from the gTLD registry constituency and the ccNSO. The latest version made available in version 2.1, see /topics/idn/implementation-guidelines.htm

The goal behind the continued revision work is to turn the guidelines into a best practise paper ensuring that the guideline directions will be used deeper into the DNS hierarchy and within TLD's where ICANN has a lesser policy relationship.

IDN Policy Development Material

The GNSO has re-instated the GNSO IDN Working Group which was originally created in May 2006. The new charter for the working group is listed online together with a call for GNSO constituency members who may wish to participate in the IDN Working Group, see http://gnso.icann.org/announcements/announcement-18nov06.htm This announcement also contains links to various GNSO IDN papers and activities.

 

IANA Repository

The IANA Repository of TLD IDN Practices was created to support the development of the IDN technology. In addition to making the IDN Tables publicly available on TLD registry websites, the TLD registries (TLD Sponsors, gTLD and ccTLD Registry Operators) may register IDN Tables with the IANA, which in turn will display them online for public access.

In order for all TLD registries to take advantage of sharing information related to their respective variance rules ICANN recommends submission of such tables to the IANA repository. See http://www.iana.org/assignments/idn/index.html
