Esri expands the power of geoportals with the release of the ArcGIS Server 10 Geoportal extension
Geoportals manage resources by registering (storing and cataloging) the resources' metadata. At version 10, the extension provides tools to simplify registering, managing, using and integrating these resources by introducing server-side resource synchronization, which replaces the harvesting tool and services from earlier versions. Once a resource is registered with the geoportal, the geoportal will monitor the resources for changes and availability and automatically update its catalog entry.
Now, searching, browsing and using geographic information system (GIS) data registered with a geoportal allows federated searching so that users can find multiple catalogs registered with the geoportal at once. The updates also give users the ability to search ArcGIS Search Services, which is an ArcGIS Server service that makes a searchable index of an organization's GIS content available to the local network. The search service is integrated into the geoportal's interface, so there is no need for users to exit the extension to find what they need.
