What does the registry publish?
There is no sample record yet that shows which fields this registry publishes.
What happens when a domain expires?
ICANN rules apply to gTLDs: after expiry there is a 0–45 day renewal grace period depending on the registrar, then a 30-day redemption period and a 5-day pending delete period; after that the name is released.
