Metadata describe the content, quality, condition, and other characteristics of spatial data sets.
Clearinghouse - a distributed network of data producers and users that is used for discovery and access to standardized metadata and geospatial data. It might typically use the Internet, internationally accepted protocols and standard methods that enable spatial data discovery and access in ways not currently available through standard web engines. Data Standards - standards for data content, classification and management that are available for the entire community of spatial data producers and users. These standards might be imposed on some producers, such as national agencies. Core Data - common base sets of data with broad geographic coverage meeting specified standards that are important to a broad variety of users.
