Sources, rights, and provenance
Source categories
- Selected public procurement and award records
- Public supply, item, and supplier-reference materials
- Connector and retrieval metadata used to measure repeatability
Rights posture
Public availability does not remove source-specific use, attribution, redistribution, or retention requirements; these remain part of the research review.
Structure, labels, and lineage
Entity resolution and normalization
The dataset models agencies, suppliers, awards, identifiers, items, and source revisions as separate entities before deriving analytical relationships.
Lineage
The lineage model preserves retrieval context and transformation history from each source record through normalized entities and derived relationships.
Quality, reconciliation, and versioning
Quality and reconciliation
Quality work covers identifier resolution, duplicate handling, source reconciliation, and coverage measurement.
Freshness and versioning
Coverage and refresh are measured per source. No currentness or refresh commitment is offered.
Delivery and access discussion
Access state
There is no public procurement feed, download, API, or service-level commitment.
Delivery discussion
An authenticated API, a scheduled export, or an agreed structured format can be scoped for this dataset. Coverage, schema, authentication, cadence, versions, rights, and support are defined with the engagement.
