MacroObservation

close: schema:Observation

One macroeconomic observation for a country and period. `attribution` is REQUIRED, not optional: the open macro sources Certvas redistributes (World Bank, IMF, ECB) require attribution as a licence condition, so a row that cannot state its attribution may not ship.

Slots

slot	range		description
`country`	`string`	required	ISO 3166-1 alpha-2 country code.
`indicator_code`	`string`	required	Source indicator code, as published by the originating body.
`indicator_name`	`string`	optional	Human-readable indicator name.
`period`	`string`	required	The period the observation covers, as published.
`macro_value`	`decimal`	optional	The observed value.
`unit`	`string`	optional	Unit of measure for the value.
`attribution`	`string`	required	Required attribution string for the source, for example "World Bank, CC BY 4.0". A licence condition of redistribution, not a courtesy.
`observed_at`	`datetime`	required	When Certvas itself observed this value. Never a proxy for publication date.
`source_ref`	`string`	required	URL or document-hash pointer into the immutable raw archive.
`license_class`	`string`	required	License Register ID governing redistribution of THIS row. Per-row rather than per-table because a single table legitimately mixes sources with different terms.
`valid_from`	`date`	required	Start of the interval over which this assertion holds.
`valid_to`	`date`	optional	End of the validity interval; NULL means current. Half-open, so `valid_from <= t < valid_to` selects without double-counting the boundary.
