GeoCat has implemented the ebRIM registry interface with the basic and ISO extension packages for the European Space Agency project ERGO. The project fits within the broader Heterogeneous Mission Accessibility Test bed (HMA-T) that works towards harmonized access to all earth observation data collected by the ESA member states at the distributed ground segments. The registry is implemented as a component of the GeoNetwork open source project and transparently publishes metadata published in GeoNetwork through the registry.
