GeoNode is a web-based application and platform for developing geospatial information systems (GIS) and for deploying spatial data infrastructures (SDI). You can browse and search for geospatial data and web services as well as upload, manage and share geospatial data. It's a complete framework for OGC-compliant web services. CKAN and pycsw are catalog systems. CKAN has a nice user interface, and pycsw has a more powerful search capability for geospatial and temporal data.
