CSW
This service is deprecated: https://data.gov/meta/data-gov-to-discontinue-csw-service-on-may-1/
The CSW (Catalog Service for Web) app is powered by PyCSW. The implementation is based on the CSW standard for geospatial metadata. It contains the same datasets in catalog.data.gov but in ISO formats (ISO 19115) which CKAN does not support very well.
A nightly job imports all datasets from CKAN. Historically, it has been treated as a component of Catalog, but it should function as its own application with a dependency on Catalog.
CSW comes in two flavors, csw-all (/csw-all) and csw-collection (/csw). csw-all exposes all 3+ million datasets while csw-collection only exposes the top-level Collections.
