GI-cat

"GI-cat features caching and mediation capabilities and can act as a broker towards disparate catalog and access services: by implementing metadata harmonization and protocol adaptation, it is able to transform query results to a uniform and consistent interface. GI-cat is based on a service-oriented framework of modular components and can be customized and tailored to support different deployment scenarios.

GI-cat can access a multiplicity of catalogs services, as well as inventory and access services to discover, and possibly access, heterogeneous ESS resources. Specific components implement mediation services for interfacing heterogeneous service providers which expose multiple standard specifications; they are called Accessors. These mediating components map the heterogeneous providers metadata models into a uniform data model which implements ISO 19115, based on official ISO 19139 schemas and its extensions Accessors also implement the query protocol mapping; they translate the query requests expressed according to the interface protocols exposed by GI-cat, into the multiple query dialects spoken by the resource service providers. Currently, a number of well-accepted catalog and inventory services are supported, including several OGC Web Services (e.g. WCS, WMS), THREDDS Data Server, SeaDataNet Common Data Index, and GBIF. A list of test endpoints is here available.
