Hi folks, I was looking for some feedback from registrars who are participating in this PDP, with regards to two items, namely (a) server-side programming languages in production use at registrars, and (b) typical CPM rates to promote 3rd party messages on their consumer-facing domain name registration websites. As we move into the "solutions" or "recommendations" part of our work for TM Claims notices in the subteams, I was contemplating suggesting that, if the TM Claims notices were to be maintained (some might want them to be eliminated entirely), that ICANN create open source sample code in the top programming languages used by registrars, to reduce the implementation costs of complying with the TM Claims notice requirements (i.e. some registrars haven't even offered new gTLDs, due to the high costs of integrating that functionality into their systems). It would be useful to know which programming language(s) dominate amongst registrars (e.g. Java, PHP, server-side Javascript, Python, .... ?), especially amongst those who've **not yet** implemented TM claims notices. As for CPM rates, we know there's a 93.7% abandonment rate (that's already an adjusted figure; the unadjusted figure was 99%) when TM claims notices are shown, as per the Analysis Group's work. Rather than trying to ascertain what the "cost" of that abandonment rate is for registrars (and registry operators), another way to look at things (perhaps more neutrally) might be to ask "What would registrars charge a 3rd party, on a cost-per-thousand impression basis, to deliver a message at checkout time?" e.g. that 3rd party message might be an Office 365 subscription offer, or some other message from a 3rd party within the order flow, i.e. to a qualified buyer who's ready to place an order at checkout time. Conceivably this could (depending on the discussions in the subteams and the broader working group/community) lead to a system whereby registrars get compensated on a CPM basis for delivering those TM Claims notices to the registrant, which would help offset some of the losses experienced due to abandoned shopping carts when a registrant is provided with the TM Claims notice. It could also lead to a variable-cost model for the TMCH, whereby fees are based on the number of times the TM is shown (e.g. a recordal in the TMCH like "CLOUD" or "HOTEL" that is shown more frequently than other recordals would cost more over time than a recordal that generates a TM Claims notice less frequently (say a hypothetical recordal for a small business like "JANE DOE KITCHEN SUPPLIES"). Anyhow, if registrars participating in this PDP have such data on programming languages and/or typical CPM rates on domain name registration sites, it would be greatly appreciated.
