MD Metadata

From Federation of Earth Science Information Partners


The root element of the ISO Metadata Standards contains information about the metadata and sections that contain other information.

Elements Domain Definition and Recommended Practice Examples
1 mdb:metadataIdentifier 0..1 mcc:MD_Identifier Unique identifier for this metadata record, assigned and maintained by the custodian of the metadata record.
Recommended Practice: value of identifier is usually the same as the name of the metadata file - for example C00500.xml.
There are two general approaches to ensuring uniqueness for these identifiers:
1. use a universal unique identifier (UUID), to distinguish it from other resources.
2. Include a namespace and a code guarenteed to be unique in that namespace in the identifier.
Example: gov.noaa.class:AERO100. In this case gov.noaa.class is a namespace and AERO100 is a code guaranteed to be unique in that namespace
2 mdb:defaultLocale 0..1 lan:PT_Locale Default language, country of origin and characterSet used in metadata.
defaultLocale is mandatory when more than one language is used in free text descriptions
3 mdb:parentMetadata 0..1 cit:CI_Citation Citation to a parent level metadata record
4 mdb:metadataScope 0..* mdb:MD_MetadataScope Scope of resource to which the metadata applies. Now includes an MD_ScopeCode and a name for a hierarchy level. Repeat if more than one scope is applicable to this metadata description.
5 mdb:contact 1..* cit:CI_Responsibility Individual and/or organization responsible for metadata creation and maintenance. Use roleCode="pointOfContact". Provide contact details, such address, phone and email.
6 mdb:dateInfo 1..* cit:CI_Date Date(s) associated with the metadata record. Highly recommend revisiting the metadata content annually to ensure that all the information is still relevant.
Creation date must be provided, others can also be provided
Use ISO 8601 extended format: YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS.
7 mdb:metadataStandard 0..* cit:CI_Citation Citation of the metadata standard used.
8 mdb:metadataProfile 0..* cit:CI_Citation Citation of the profile(s) of the metadata standard used.
9 mdb:alternativeMetadataReference 0..* cit:CI_Citation Citation to alternative metadata for the resource.
10 mdb:otherLocale 0..* lan:PT_Locale Alternative language, country of origin and characterSet used in metadata.
11 mdb:metadataLinkage 0..* cit:CI_OnlineResource Online location information for the metadata.
12 mdb:spatialRepresentationInfo 0..* msr:MD_SpatialRepresentation Spatial representation properties for Gridded datasets.
13 mdb:referenceSystemInfo 0..* mrs:MD_ReferenceSystem Identification of the horizontal projections, vertical datums and temporal reference systems used. Mandatory if spatialRepresentationType in dataIdentification is vector, grid, or tin.
14 mdb:metadataExtensionInfo 0..* mex:MD_MetadataExtensionInformation Description of extended metadata fields and structure.
15 mdb:identificationInfo

1..* mri:MD_DataIdentification
   - or-
Choose one and repeat identificationInfo if needed.
16 mdb:contentInfo 0..* mrc:MD_ContentInformation information about the feature catalogue, or descriptions of the coverage and the image data characteristics.
17 mdb:distributionInfo 0..* mrd:MD_Distribution nformation about acquiring the resource.
18 mdb:dataQualityInfo 0..* mdq:DQ_DataQuality (ISO 19157-2) Data quality quality reporting for the resource.
19 mdb:resourceLineage 0..* mrl:LI_Lineage Data processing history (provenance) for the resource.
20 mdb:portrayalCatalogueInfo 0..* mpc:MD_PortrayalCatalogue A portrayal catalogue is a collection of defined symbols used to depict humans, features on a map.
21 mdb:metadataConstraints 0..* mco:MD_Constraints The limitations or constraints regarding the use and access of the metadata.
22 mdb:applicationSchemaInfo 0..* mas:MD_ApplicationSchemaInformation Information about the conceptual schema of the dataset.
23 mdb:metadataMaintenance 0..1 mmi:MD_MaintenanceInformation Document recent metadata record edits. When the metadata is generated automatically, use this section to document the source and transform tool in the maintenanceNote field.
24 mdb:acquisitionInformation 0..* mac:MI_AcquisitionInformation Information about the platforms and instruments collecting the data.
