GeoNetwork OpenSource is an open source geospatial data catalog service host, metadata creation and management system, and basic web mapping platform that is in broad use by a number of international organizations in deploying their Spatial Data Infrastructure (SDI). GeoNetwork implements a set of key international geospatial standards, including catalog service (OGC Catalog Services for Web [CSW], z39.50), metadata (FGDC, ISO19139, Dublin Core [for general documents]), and map visualization (OGC Web Map Services [WMS]) standards that allow for integration of GeoNetwork services into national (i.e. NBII, Geospatial OneStop) and international (i.e. GEOSS) geospatial data discovery and access programs.
