Description

MCO 1.3 is an XML Schema implementation derived from ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 6.5.4. It includes elements for describing resource and metadata constraints. The XML schema was encoded using the rules described in ISO/TS 19139:2007.

XML Namespace for mco 1.3

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

XML Schema for mco 1.3

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

constraints.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 1: Fundamentals, Clause 6.5.4. It was created using the encoding rules defined in ISO 19118, ISO 19139.

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

  • MD_Constraints

  • MD_LegalConstraints

  • MD_SecurityConstraints

  • MD_Releasability

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

  • MD_ClassificationCode

  • MD_RestrictionCode
