It follows a metadata-driven approach where datasets are documented by standardized discovery metadata that are exchanged through standardized Web services. The GCW Data Portal can interface with scientific and other data providers with WMO-specific interfaces like real-time exchange through WMO GTS. For all other purposes, the Internet is used as a communication network. A critical component of the discovery metadata exchanged is the application of a standardized semantic annotation of data and interfaces, for example using ontologies as well as linkages between datasets and additional information useful to fully understand a dataset (e.g. WIGOS information).
