ISO 19115:2003/19139

ISO 19115:2003 defines the schema required for describing geographic information and services. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data.

ISO 19115:2003 is applicable to:

• the cataloguing of datasets, clearinghouse activities, and the full description of datasets;
• geographic datasets, dataset series, and individual geographic features and feature properties.

ISO 19115:2003 defines:

• mandatory and conditional metadata sections, metadata entities, and metadata elements;
• the minimum set of metadata required to serve the full range of metadata applications (data discovery, determining data fitness for use, data access, data transfer, and use of digital data);
• optional metadata elements - to allow for a more extensive standard description of geographic data, if required;
• a method for extending metadata to fit specialized needs.

ISO 19139 provides the XML implementation schema for ISO 19115 specifying the metadata record format and may be used to describe, validate, and exchange geospatial metadata prepared in XML.
