Scope
This document establishes the XML encoding rules for the conceptual model of geographic information resources, which is used to standardize the description of geographic information resource types. The encoding rules support the UML models adopted by the national geographic information series standards and the UML-specific standards used by them, and use XML as the encoding for the output data structure.
The encoding rules described in this document are not applicable to the UML application model encoding of geographic elements (for related rules, please refer to ISO 19136).
