AB: Metadata standards in the earth sciences have evolved considerably over the last several decades. Drivers of this evolution have included community needs initially expressed as extensions and then incorporated into future standards, as well as the recognition of the importance of preserving understanding relative to data discovery. The ISO Geographic Metadata Standard, 19115, includes many features that originally emerged in the Directory Interchange Format (DIF) and as extensions to the FGDC Metadata Standards. The ISO Standard also includes new and powerful features that extend the capabilities of the standard considerably beyond previous standards. These features include a spectrum of metadata from granule to collection levels, user feedback, reasonable on- line resources, multiple spatial and temporal extents, and a very general mechanism for describing data quality. I will describe these features with examples of how they will be used at NGDC.
