mdb:MD_Metadata
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.
|
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.
|

| 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.
|
