【国外标准】 Geographic information - Metadata - Part 3: XML schema implementation for fundamental concepts

Defines an integrated XML implementation of ISO 19115 1, ISO 19115 2, and concepts from ISO/TS 19139 by defining the following artefacts: a) a set of XML schema required to validate metadata instance documents conforming to conceptual model elements defined in ISO 19115 1, ISO 19115 2, and ISO/TS 19139; b) 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; c) an Extensible Stylesheet Language Transformation (XSLT) for transforming ISO 19115-1 metadata encoded using the ISO/TS 19139 XML schema and ISO 19115 2 metadata encoded using the ISO/TS 19139 2 XML schema into an equivalent document that is valid against the XML schema defined in this document.
