MRL 1.3 is an XML Schema implementation derived from ISO 19115-1, Geographic Information - Metadata - Part 2: Extensions for acquisition and processing, Clause 6.3.3. It includes elements for describing resource lineage. The XML schema was encoded using the rules described in ISO/TS 19139:2007.

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

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

lineage.xsd implements the UML conceptual schema defined in ISO 19115-1, Geographic Information - Metadata - Part 2: Extensions for acquisition and processing, Clause 6.3.3. It was created using the encoding rules defined in ISO 19118, ISO 19139.

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

lineageImagery.xsd implements the UML conceptual schema defined in ISO 19115-2, Geographic Information - Metadata - Part 2: Extensions for acquisition and processing, Clause 6.3.3. Information about lineageImagery.xsd can be obtained from https://schemas.isotc211.org/19115/-2/mrl/2.2.0/

The mrl 1.3 namespace imports these other namespaces:

Schematron rules for validating instance documents required for a complete validation are:

Other schematron rule sets that maybe required for a complete validation (optional direct from MD_Metadata or indirectly through associations) are:

Schematron rules for validating instance documents of the mrl 1.3 namespace are in mrl.sch.

When revisions to these schema become necessary, they will be managed in the ISO TC211 Git Repository.
