Geographic information — Metadata — Part 3: XML schema implementation for fundamental concepts
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).
