本文档通过定义以下工件来定义ISO 19115-1和ISO 19115-2的集成XML实现:—？验证符合ISO 19115-1和ISO 19115-2中定义的概念模型元素的元数据实例文档所需的XML模式集；和—？一组ISO/IEC 19757-3（Schematron）规则，用于实现ISO 19115-1和ISO 19115-2 UML模型中未通过XML模式验证的验证约束。本文档描述了用于从与元数据相关的ISO地理信息概念模型生成XML模式的过程。XML模式直接从概念UML模型（8.5）生成。

This document defines an integrated XML implementation of ISO 19115-1 and ISO 19115-2 by defining the following artefacts:

—     a set of XML schema required to validate metadata instance documents conforming to conceptual model elements defined in ISO 19115-1 and ISO 19115-2; and

—     a set of ISO/IEC 19757-3 (Schematron) rules that implement validation constraints in the ISO 19115-1 and ISO 19115-2 UML models that are not validated by the XML schema.

This document describes the procedure used to generate XML schemas from ISO geographic information conceptual models related to metadata. The XML schemas are generated directly from the conceptual UML model (8.5).
