Description

MRC 1.3 is an XML Schema implementation derived from ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals AMENDMENT 1, Clause 6.5.9. It includes elements for describing resource structure and content. The XML schema was encoded using the rules described in ISO/TS 19139:2007.

XML Namespace for mrc 1.3

The namespace URI for mrc 1.3 is https://schemas.isotc211.org/19115/-1/mrc/1.3.

XML Schema for mrc 1.3

mrc.xsd is the XML Schema document to be referenced by XML documents containing XML elements in the mrc 1.3 namespace or by XML Schema documents importing the mrc 1.3 namespace. This XML schema includes (indirectly) all the implemented concepts of the mrc namespace, but it does not contain the declaration of any types.

content.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals AMENDMENT 1, Clause 6.5.9. It was created using the encoding rules defined in ISO 19118, ISO 19139.

https://schemas.isotc211.org/19115/-1/mrc/1.3.0/content.xsd contains the following classes:

  • AbstractMD_ContentInformation

  • MD_FeatureCatalogueDescription

  • MD_FeatureCatalogue

  • MD_CoverageDescription

  • MD_ImageDescription

  • MD_AttributeGroup

  • MD_RangeDimension

  • MD_SampleDimension

  • MD_Band

  • MD_FeatureTypeInfo

https://schemas.isotc211.org/19115/-1/mrc/1.3.0/content.xsd contains references to the following codelists:

  • MD_CoverageContentTypeCode

  • MD_ImagingConditionCode

contentInformationImagery.xsd implements the UML conceptual schema defined in ISO 19115-2, Geographic Information - Metadata - Part 2: Extensions for acquisition and processing, Clause 6.5.9. Information about contentInformationImagery.xsd can be obtained from https://schemas.isotc211.org/19115/-2/mrc/2.2.0/

https://schemas.isotc211.org/19115/-1/mrc/1.3.0/mrc.sch

  • MD_SampleDimension - if count (m axValue + m inValue + meanValue) \> 0 then units is mandatory

  • MD_FeatureCatalogueDescription - if Feature Catalogue not included with resource and MD_FeatureCatalogue not provided then featureCatalogueCitation \> 0

  • MD_Band - if count(boundMax + boundMin) \> 0 then boundUnits is mandatory
