3 GEO Discovery and Access Broker (DAB) GEO DAB is a brokering framework that interconnects hundreds of heterogeneous and autonomous supply systems (the enterprise systems constituting the GEO metasystem) by providing mediation, harmonization and transformation capabilities.

(Python) Server side APIs: REST/JSON APIs OpenSearch APIs.

7 GEO DAB View Definition: Subset of the whole resources defined by applying, via the DAB, a set of clauses Discovery clauses (e.g. spatial envelope, keywords, sources, etc.) Access clauses (e.g. data format, access protocol, CRS, etc.) Defined View exposed on the Portal Consumer-defined View i.e. Client-side These views are available only for the client application which defined the view. Provider-defined View i.e. Server-side These views are available for all client applications.
