ISO(c) GMX schema ReadMe.txt ------------------------------------------------------------------------------ Geographic Metadata XML (GMX) Schema GMX is a component of the XML Schema Implementation of Geographic Information Metadata documented in ISO/TS 19139:2007. GMX includes all the definitions of http://www.isotc211.org/2005/gmx namespace. The root document of this namespace is the file gmx.xsd. The most current schemas are available at: http://standards.iso.org/ittf/PubliclyAvailableStandards/ISO_19139_Schemas/ ------------------------------------------------------------------------------- 2012-07-13 Nicolas Lesage on behalf of the ISO/TC 211 XML Maintenance Group * Update of readme.txt file and schema annotations * Use of absolute schema locations of imported namespaces * Simplification of the schema location of included XML Schemas * Adoption of W3C Implementation of XLink: - schemaLocation changed to: http://www.w3.org/1999/xlink.xsd - xlink:simpleLink renamed xlink:simpleAttrs * Addition of the version attribute to the schema element. The value of this attribute is expected to be the date of the last release of the XML schemas (e.g. 2012-07-13 for this release) * Include root XML Schema document in all schema documents Validation: Schemas have been validated with XML Spy 2010 Rel. 2 (MSXML 6.0) 2009-03-16 Marcellin Prudham & Nicolas Lesage * Change of GML namespace: http://www.opengis.net/gml (GML 3.2) => http://www.opengis.net/gml/3.2 (GML 3.2.1=ISO 19136) Note: ISO/TS 19139:2007 (published 2007-04-17) normatively reference ISO 19136 which was published 2007-08-23. The major change applied to ISO 19136 is the change of the namespace URI. Previous release of GMX are not compliant with ISO/TS 19139:2007 Validation: Schemas have been validated with XSV 2.10, Xerces J 2.7.1 and XML Spy 2009 (2009-03-02, IGN / France - Nicolas Lesage / Marcellin Prudham) 2006-05-04 Marie-Pierre Escher & Nicolas Lesage * First official release of GMX * GMX XML Schema files were generated from ISO/TC 211 UML class diagrams in accordance with ISO/TS 19139:2007.
