ISO/TS 19139-1:2019

This document defines XML based encoding rules for conceptual schemas specifying types that describe geographic resources. The encoding rules support the UML profile as used in the UML models commonly used in the standards developed by ISO/TC 211. The encoding rules use XML schema for the output data structure schema.
The encoding rules described in this document are not applicable for encoding UML application schema for geographic features (see ISO 19136 for those rules).
