With the help of NORC at the University of Chicago, the pioneer of one of the earliest studies into WHOIS accuracy, ICANN is publishing NORC's suggested model for implementing this statistical analysis. Taking into account recent WHOIS developments, such as the adoption of the new 2013 Registrar Accreditation Agreement (2013 RAA), the model examines a WHOIS record for each of the validation perspectives highlighted in SSAC-58 [PDF, 490 KB], namely, syntactic, operational, and identity validation, and assigns a scoring methodology. These in turn will translate into a finding of accuracy labels, based on range of possibilities, such as: No Failure, Minimal Failure, Limited Failure, Substantial Failure, and Full Failure, which will be reported on a regular basis, and tracked over time. The model also describes a sampling methodology to ensure that a statistically significant number of records are examined to provide adequate geographic scope, and that enable a comparison of accuracy levels associated with new gTLDs and legacy gTLDs, as well as other comparisons.
