CORDEX Data Federation Building System Idea

The CORDEX Data Federation Building System aims to store CORDEX data conforming to metadata conventions, with data nodes like DMI, DKRZ, BADC, and SMHI acting as key providers. It emphasizes data protection through authorization services, with portals offering search functionality, data shopping baskets, user registration, and more. The system facilitates data access and generation of Thredds Metadata, supporting efficient download and openDAP subsetting functionalities.
