Data quality audit

Freshness and metadata checks from the public catalog.

This audit turns the current CKAN and ArcGIS pull into a launch-cleanup queue: modified dates, owner fields, notes, licenses, datastore coverage, selected layer checks, and source URLs.

The generated CSV keeps each source's owner, category, modified date, age bucket, issue summary, resource counts, datastore coverage, and source URL together.

Launch cleanup stance

  • Use source-system metadata; do not invent freshness or quality scores.
  • Review older records with departments before hiding or changing them.
  • Keep cleanup notes tied to CKAN package and ArcGIS layer URLs.
  • Separate portal usability improvements from source-system governance decisions.

Core metadata completeness

170 of 170 CKAN packages currently have owner, modified date, notes, and license fields available in the public pull.

Datastore coverage

166 packages expose at least one datastore-backed resource in the current CKAN package pull.

Launch cleanup queue

Rows are sorted by metadata issue count and age. The queue is a working review list, not a claim that a source is invalid.
