What metadata and services are available for search?
Contains 27,318 NGDC records. (30 January 2012 (MST))
Contains 28,725 records total. (30 January 2012 (MST))
How do the metadata and services get harvested?
Set up of the harvest nodes are managed by Dave Neufeld and Anna Milan. If there are problems with the source metadata Anna will advise the appropriate author as needed. Data managers do not need to manage the harvest and synchonization process - HOWEVER, it is recommended that each data manager take some time to review the metadata in Geoportal.
Synchronized weekly. All metadata records are re-harvested and indexed automatically.
Selection of a distributed search option enables searching remote catalogs from the geoportal's interface. Lucene search options may differ.
