This extension provides the API that enables a CKAN site to be checked by the Dead or Alive link checker service. It handles saving the results posted by the link checker in CKAN’s database and adds various broken link reports to the CKAN site. Features include configurable recheck intervals, minimum fail thresholds before marking resources as broken, and report pages showing datasets with broken links including maintainer information. Works with the separate deadoralive Python service that performs the actual link checking.
