Usage metrics are aggregated daily counts with no personal identifiers.
Metrics definitions
- Snapshots are individual captured pages with a timestamped record.
- Pages are URL groups that may have multiple snapshots over time.
- Last capture date is a proxy for freshness and reflects archive capture time (UTC), not source update time.
- Annual and ad-hoc editions in the existing corpus retain their labels and capture dates. No future cadence is assumed; any future capture requires a separately authorized data-continuity decision.
- Usage counts are aggregated daily totals (search requests, snapshot views, report submissions).
Monthly impact report
