Nimilistan

Nimilistan is a Finnish term meaning a list of names, typically a roster or registry used to identify participants or members of a group. The canonical form is nimilista, while nimilistan denotes the genitive case (for example, information about the nimilistan or the organizer of the nimilistan). The term is used in everyday language to refer to any compiled listing of individuals, often including fields such as etunimi (given name), sukunimi (surname), syntymäaika (date of birth), osoite or sähköpostiosoite (email), and puhelinnumero (phone number).

Nimilistan can be maintained in paper form or in digital databases and spreadsheets. Common use cases include school enrollments, sports club rosters, event registrations, attendee check-ins, and workplace contact lists. Because such lists may contain personal data, their collection, storage, and processing are subject to privacy regulations, including the European Union's General Data Protection Regulation (GDPR) and Finland's data protection rules. Organizations should collect only necessary data, inform individuals about purposes, implement access controls, and define retention periods.

Related terms include osallistujaluettelo (participant roster), jäsenluettelo (membership list), rekisteri (registry), and henkilötietorekisteri (personal data registry). Nimilistat thus function as a basic data structure in administrative and organizational contexts, with governance focused on data minimization and privacy.
