ROLL
Electoral roll data
Entries as published by the Election Commission of India: name, relation
name, age, gender, house number, part and serial number, and the polling
station a person is registered at. Taken from published rolls; not collected
from individuals and not augmented from other sources.
DERV
Derived attributes
Some fields are computed rather than published — surname extracted from a
name, and a community grouping inferred from that surname. These are
inferences, not statements of fact about any individual, and they carry the
provenance of which classification pass produced them.
ACCT
Account data
For platform users: a username, a password hash, the geography the account
is scoped to, and sign-in activity. Accounts are provisioned by an
administrator and are never self-registered.
