Current RDAP / WHOIS
Useful for the present registrar, status codes, nameservers, current registration events, expiration information, and other fields the registry or registrar exposes.
Registration history
CURRENT REGISTRATION DATA IS A SNAPSHOT, NOT A TIME MACHINE.
WHOIS and RDAP are useful for current registration facts. They should not be treated as a complete historical record of who used a domain, what was hosted there, or whether earlier registration periods existed.
What RDAP is for
START WITH WHAT THE SOURCE ACTUALLY SAYS IT PROVIDES.
ICANN describes the Registration Data Access Protocol, or RDAP, as a way to access current registration data and as the replacement for the older WHOIS protocol. ICANN's lookup tool returns registration data from registry operators and registrars in real time.

Research implication: a current record is strong evidence of what the registration system reports now. By itself, it is not a complete archive of every prior registrant, prior website, or prior registration period.
Keep the evidence types separate
DIFFERENT SOURCES ANSWER DIFFERENT QUESTIONS.
Archived web pages
Useful for showing that a domain or website was publicly used by a certain date and what content or links were visible in an archived capture.
Historical registration services
Useful when available for comparing older registration snapshots. Coverage varies, and historical records may be incomplete or redacted.
Contemporaneous records
Old emails, invoices, screenshots, account records, and third-party pages can independently establish use or control at a particular time.
The important mismatch
WHAT IF AN ARCHIVE PREDATES THE CURRENT CREATION DATE?
Do not force the two sources into one story. Record both facts. If a current registration record reports one date while an independently dated archive proves the domain was already in use earlier, the archive is evidence of earlier use and the current record is evidence of the present registration record. The gap becomes a research question.
Do not jump from “the current date is later” to “the current data is false.” The safer conclusion is that the current registration snapshot does not, by itself, explain the earlier evidence or establish continuity between the two dates.
Our publication rule
WE DO NOT TURN ONE DATE INTO A COMPLETE OWNERSHIP HISTORY.
Current registration epoch
Record the current registration event/date exactly as the authoritative RDAP or registry source reports it.
Earliest archived evidence
Record the earliest independently located dated evidence of public use separately.
Historical continuity
Mark continuity as established only when the evidence actually supports it. Otherwise use “gap observed” or “unknown.”
Ownership claims
Do not infer a prior owner from a current registrant, and do not infer current ownership from an old archived page.
Keep digging
