IOOS Catalog Important Periods and Schedules

The IOOS Registry is responsible for downloading metadata from external sources. The central WAF acts as a repository for all the metadata that the registry downloads. CKAN will periodically download metadta from the central WAF into it’s internal database. CKAN will occasionally synchronize with PyCSW’s database.

It’s helpful for providers to know the periods and intervals the system uses for the various phases.

Registry

The registry harvests all published harvest records at 18:00Z every day.

CKAN

The IOOS Catalog will harvest after each registry harvest or exactly 24h after the last harvest, whichever happens first.

PyCSW

PyCSW is synchronized with CKAN every hour.

Other

Cleanup scripts cleanup duplicate datasets that will sometimes be created if a CKAN harvester fails to fully synchronize with the central WAF. These cleanup scripts run once a week on Sundays at 00:00Z.
