Gathered here for ease of access are materials from ICANN relevant to applying for a new TLD. There is a voluminous amount of material on ICANN’s site, but it is not always easy to locate.
ICANN’s Guide to Applying for a new TLD
ICANN’s mini-site devoted to new gTLDs. Lots of useful information.
The latest Applicant Guidebook is available in multiple languages from this page. This enormous instruction manual also contains the draft Registry Agreement that all new gTLD registries will have to sign with ICANN.
ICANN’s Similarity Algorithm, a.k.a. “Sword Algorithm.” Excessively expensive software that evaluators will use to see if your proposed TLD conflicts with others. Current version doesn’t work well. ICANN has said (Nov 26 2008 teleconf) that it is only an “aid” to evaluators, so humans will verify the results.
Trademark Clearing House. Description of the Trademark Clearing House, which is important for the Sunrise Period and the Trademark Claims Service. January 2012.
Final Report of the Implementation Recommendation Team (IRT). ICANN asked the people from the intellectual property/trademark group to come up with their own rules since they didn’t like anything that the rest of ICANN was proposing. Most of the intellectual property protection measures required of new gTLD registries stem from this report.
