3. GeoNetwork OpenSource
• GeoNetwork is a Metadata catalog
• Used to store, manage en find metadata for spatial
datasets
• GeoNetwork complies multiple standards
• GeoNetwork has an Mapviewer to directly combine
located datasets
• Using harvesting several Geonetwork nodes can form a
network. Harvesters can also be used to import metadata
from WMS, Local file system, etc
• In a default install GeoServer is included
