Definitions
In plain terms
A column named close is not enough. You also need the instrument, venue or source, currency, adjustment basis, interval, calendar, and field meaning.
Technical
A series key should encode or reference all dimensions whose change would alter comparability, including instrument, field, source, frequency, unit, adjustment, and valid-time policy.
Scope
The dimensions are dataset-specific; the glossary does not prescribe one universal composite key.
Examples
- A governed dataset records series identity explicitly instead of inferring it from an ambiguous field.
Common misconceptions
- Series Identity does not have one universal meaning without its stated market, source, and time context.
