Before a source enters the dataset it must carry 6 things: a stable identifier, the publisher and title, a deep link to the exact figure, an access date, a type and preference tier, and any stated reuse terms. This mirrors the source schema and keeps every citation traceable.
- 6 required fields per source.
- Deep links only — a citation must land on the exact figure.
- Drives the source hierarchy and confidence defaults.
Required fields
| Field | Requirement | Why |
|---|---|---|
id | Stable, unique kebab-case identifier. | Permanent identifier so citations never break across versions. |
title / publisher | The publishing organization and document title. | Lets a reader judge authority and find the original. |
url (deep link) | A deep link to the specific page or table, not a homepage. | A citation must land on the exact figure, not a site root. |
accessedDate | ISO date the source was last accessed. | Records when the linked content was verified. |
type / tier | Source type (official, IGO, market, news) and preference tier. | Drives the source hierarchy and confidence defaults. |
license / reuse note | Note any reuse terms where the publisher states them. | Downstream consumers need to know reuse constraints. |
