MRL 2.0 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, Clause 8 and implementation approach from ISO/TS19115-3, Clause 8.

mrl.xml

The namespace URI for mrl 2.0 is http://standards.iso.org/iso/19115/-3/mrl/2.0.

mrl.xsd is the XML Schema document to be referenced by XML documents containing XML elements in the mrl 2.0 namespace or by XML Schema documents importing the mrl 2.0 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, and the implementation approach described in ISO 19115-3 and contains the following classes (codeLists are bold): LI_Lineage, LI_ProcessStep, and LI_Source
