MD IdentificationInformation.png

Elements			Definition and Recommended Practice
1	metadataIdentifier	0..*	Code that uniquely identifies 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. For 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	defaultLocale	0..*	Default language, country of origin and characterSet used in metadata. Locale is mandatory when more than one language is used in free text descriptions
3	parentMetadata	0..*	Citation to a parent level metadata record
4	metadataScope	0..*	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	contact	1..*	Individual and/or organization responsible for metadata creation and maintenance. Use roleCode="pointOfContact". Provide contact details, such address, phone and email.
6	dateInfo	1..*	Date of last metadata update. Highly recommend revisiting the metadata content annually to ensure that all the information is still relevant. Use ISO 8601 extended format: YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS.
7	metadataStandard	0..*	Citation of the metadata standard used.
8	metadataProfile	0..*	Citation of the profile(s) of the metadata standard used.
9	alternativeMetadataReference	0..*	Citation to alternative metadata for the resource.
10	otherLocale	0..*	Alternative language, country of origin and characterSet used in metadata.
11	metadataLinkage	0..*	Online location information for the metadata.
12	spatialRepresentationInfo	0..*	Spatial representation properties for Gridded datasets.
13	referenceSystemInfo	0..*	Identification of the horizontal projections, vertical datums and temporal reference systems used. Mandatory if spatialRepresentationType in dataIdentification is vector, grid, or tin.
14	metadataExtensionInfo	0..*	Description of extended metadata fields and structure.
15	identificationInfo MD_DataIdentification SV_ServiceIdentification	1..*	Choose one and repeat identificationInfo if needed.
16	contentInfo	0..*	information about the feature catalogue, or descriptions of the coverage and the image data characteristics.
17	distributionInfo	0..*	nformation about acquiring the resource.
18	dataQualityInfo	0..*	Data quality quality reporting for the resource.
19	resourceLineage	0..*	Data processing history (provenance) for the resource.
20	portrayalCatalogueInfo	0..*	A portrayal catalogue is a collection of defined symbols used to depict humans, features on a map.
21	metadataConstraints	0..*	The limitations or constraints regarding the use and access of the metadata.
22	applicationSchemaInfo	0..*	Information about the conceptual schema of the dataset.
23	metadataMaintenance	0..*	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	acquisitionInformation	0..*	Information about the platforms and instruments collecting the data.
