You can't compare apples with pears

CENTR's RRDG working group gets to grips with data standardisation

To measure is to know, the saying goes. But what should a registry be measuring? And how can a registry make sure its measured data lends itself to comparison with other TLDs? To answer those questions, CENTR has teamed up with SIDN and several other operators of country-code domains (ccTLDs) to establish the Registry Registrar Data Group (RRDG).

On the RRDG, we'll be working to develop shared data classifications, standards and frameworks. In simple terms, we'll be aligning various aspects of our data recording activities, so that registries for neighbouring countries know how to interpret one another's data in the context of their local markets. This blog post outlines the projects we're currently working on.

DIT

The RRDG has developed a domain industry taxonomy, or DIT for short. Based on standards such as SBI, NACE and SIC, the DIT categories address various problems discovered by crawling and classifying business websites. The aim of the project is to enable the precise international comparison of industries and internet density. It will then be possible to see things such as what percentage of hotel and catering businesses have domain names.

Domain lifecycle metrics

We've defined a set of terms and concepts commonly used in domain registration analyses. Definition will mean that registries and registrars can use the terms in their internal and external reports in ways that others understand. The initiative should also make comparison of TLD statistics more straightforward in the context of, for example, market research activities.

Business model classifications

In collaboration with registrars, the RRDG has defined seven key business models. The models enable registries to group their registrars on the basis of the way they operate. That in turn will mean that registrars can be given useful information about how their performance compares with others who operate on a similar model. For example, we'll be able to provide churn data that distinguishes between access providers and retail/hosting service providers.

Why get involved?

Removing uncertainty about how things are defined clears the way for talking about what collected data actually shows. And that should yield conclusions that will be valuable in all sorts of ways. Say, helping registrars to run effective marketing campaigns. As a .nl registrar, getting involved in this project will make it easier to put the data we send you to practical use.
