Current record

Current claims returned for this entity, grouped by provenance subject. The table exposes the source identifier recorded for each claim.

Point-in-time

Query retained claim coordinates under bitemporal-read/v1. Most facts have no superseded row; dates outside retained coverage may return no prior version, and diffs require both coordinates.
