Mandatory, Conditional and Optional Elements for Marine Geographic Datasets¶
Mandatory metadata elements are elements that must appear in any MCP metadata record.
Conditional metadata elements are elements that are mandatory if a certain condition exists. For example, it is mandatory to have a metadata language element if the language encoding is not one of the common ISO10646-1/Unicode character sets such as UTF-8.
Optional metadata elements are elements that don’t need to be present but are recommended to maximize interoperability.
Mandatory Metadata Elements for Marine Geographic Datasets¶
About the Dataset:

D6 | Bounding Box | mcp:MD_Metadata/gmd:identificationInfo/mcp:MD_DataIdentification/gmd:extent/gmd:EX_Extent/gmd:geographicElement/gmd:EX_GeographicBoundingBox |
D7 | Temporal Extent | mcp:MD_Metadata/gmd:identificationInfo/mcp:MD_DataIdentification/gmd:extent/gmd:EX_Extent/gmd:geographicElement/mcp:EX_TemporalExtent |
Rationale for making D7 and D8 mandatory: In earlier versions of the MCP documentation (eg. http://www.aodc.gov.au/files/MarineCommunityProfilev1.4.pdf), D7 and D8 were made conditional on the hierarchyLevel being set to ‘dataset’. However the subject (and the title of this section) in previous documentation has always been about ‘Metadata Elements for Marine Geographic Datasets’. Given that we are referring to ‘datasets’, this condition would appear to be trivially satisfied and we can safely make elements D7 and D8 mandatory.
About the Metadata record:
No. | Name | XPath |
---|---|---|
M1 | File Identifier | mcp:MD_Metadata/gmd:fileIdentifier |
M2 | Standard Name | mcp:MD_Metadata/gmd:metadataStandardName |
M3 | Standard Version | mcp:MD_Metadata/gmd:metadataStandardVersion |
M4 | Date Stamp | mcp:MD_Metadata/gmd:dateStamp |
M5 | Revision Date | mcp:MD_Metadata/mcp:revisionDate |
M6 | Point of Contact | mcp:MD_Metadata/gmd:contact/gmd:CI_ResponsibleParty |
Rationale for making M2 and M3 and Mandatory: The MCP is implemented in both a production version and an experimental version. Implementations need to be able to distinguish between these versions of the MCP.
