3.1.3: Metadata Catalogs
Create and Maintain Catalogs Other Information:
Metadata catalogs will advertise the existence of shared data and will contain information about all data assets contained
in the associated shared space (including databases, system output files, web pages, documents, and access services). At a
minimum, the mandatory discovery metadata elements in the DDMS must be represented within metadata catalogs for any data asset
posted to a shared space. COIs will establish and maintain catalogs. Each catalog may be organized according to the community-defined
ontology. An Enterprise catalog will be established that links to community catalogs, effectively creating a “catalog of catalogs.”
The Enterprise catalog will also contain metadata for data posted by users and applications without a specific COI affiliation.
Catalogs will be searchable by applications or through user-friendly, web-based interfaces. The web-based interfaces will
have a consistent look and feel and will support posting of metadata to the catalog and data to the shared space. The catalogs
will also be searchable, either manually or automatically via agents, through application programming interfaces. All metadata
catalogs will adhere to Enterprise discovery interface standards to allow searches within a catalog or across catalogs.
