【国外标准】 Information Technology - North American Profile of ISO 19115:2003 - Geographic Information - Metadata (NAP - Metadata)

The North American Profile of ISO 19115:2003, Geographic information - Metadata, is intended to identify geospatial metadata that are needed for North American organizations to describe their geospatial data, including dataset and dataset series, and related Web services. It is based on ISO 19115:2003, Geographic information - Metadata, and ISO 19106:2004, Geographic information - Profiles. It also includes service metadata from ISO 19119:2005, Geographic information - Services, and implementation perspectives from ISO/TS 19139:200,7 Geographic information - Metadata - XML schema implementation. As outlined in ISO 19106:2004, Geographic Information - Profiles, it satisfies conformance Class 1 since it defines a pure subset of ISO 19115:2003, Geographic information - Metadata, and ISO 19119:2005, Geographic information - Services. Retained metadata elements have been selected to enhance discovery of geographic information within North America and to minimize authorized duplications. The extension of code lists is also intended to support to geographic information discovery. Annex A provides the adjustments made to the ISO 19115:2003, Geographic information - Metadata, and ISO 19119:2005, Geographic information - Services UML models.
