Source citations and verification
Quoin keeps source evidence attached to individual facts. Applications should show the display-ready official source route while preserving dates, quality flags, and property-link scope.
Start freeTwo evidence views
- provenance is developer-facing audit data expanded from opaque source references.
- sources contains display-ready official portals, exact lookup inputs, covered fields, access notes, and fallbacks.
What applications must preserve
Keep the fact’s semantic identity, typed value and unit, effective period, release date, status or null meaning, source reference, quality flags, and link scope together.
Safe human verification
Use stable official document pages or human search portals with exact lookup inputs. Never present raw ArcGIS REST, JSON, download, or session-bound MyTax URLs as the verification link.
