D.3
XML Schema Implementation of NGMP Extensions of ISO 19115
Introduction
This clause defines the XML encoding for the NGMP Extensions of ISO 19115 defined in D.1. This XML schema implementation follows the encoding rules stated in ISO/TS 19139 (8 – Encoding rules). The exceptions and the implementations based on external types are detailed in this clause. This clause uses the UML notation commonly used in the ISO 19100 series of International Standards and the specific notations defined in clause in 5.4 of ISO/TS 19139.#

Specification of the XML Schema implementation
Organization of the ngmp namespace
This namespace contains the XML Schema Implementation of NGMP extensions of ISO 19115. The root and unique XML Schema Document of this namespace is ngmp.xsd.
ngmp.xsd
This XML schema implements the UML conceptual schema defined in clause D.1. It directly imports the XML Schema definition from gco and gmd namespaces.
All the concepts defined in clause D.1and described in clause D.2are implemented in this XML schema document in conformance with the encoding rules defined in Clause 8 of ISO/TS 19139.
