Metadata Set Identifier
This is a value uniquely identifying the original and published versions of the metadata set.
|
String
It is strongly recommended to provide a unique identifier (e.g. UUID, URI, URN or URL). The value shall be the identifier of an existing metadata set.
|
0..1 | Mandatory if used in a catalogue. | It should be the value which enables the user to access a metadata set by its identifier. It is usually generated automatically by the catalogue system. | b6986b32-1336-487a-8d4d-45b317d8a31f | |

Metadata Linkage
This element refers to the online location where the metadata is available.

Parent Metadata Set
This refers to the metadata set of a resource to which this resource is a subset (child). Typically, the parent metadata set of a dataset metadata set is the metadata set of the corresponding dataset series.
|
Parent Metadata Reference | 0..1 | This element is not applicable to services It is mandatory if an upper-level hierarchy exists, typically if a dataset pertains to a dataset series | As title is mandatory in ISO mdIdentifier will be mapped both to identifier and title | 123e4567-e89b-12d3-a456-426655440000 | |

Metadata Default Locale
This is the locale in which the metadata elements are primarily expressed.
|
Locale | 1 | MDDLOC.identifier is never set | Metadata principal locale should be English and should be encoded in UTF8 | eng | |

Metadata Translation
This defines the locale in which some metadata elements may be translated

Metadata Responsible Party
Information about the party responsible for the metadata.
|
Responsible Party | 1..* | The party.role is usually defaulted to pointOfContact.
The party.orgName can be defaulted to "To be determined" but it is strongly recommended that each organization set up its own default values.
The party.Name should be used according local legislation on storing personal data

Name of organization: Danish Defence Acquisition and Logistics Organisation

Metadata Date Stamp
The date which specifies when the metadata record was created or updated.
|
Date or DateTime
|
1 | Default value is the date of the current day  Should be a DateTime; | 2017-10-12 or 2017-10-12T11:15:00 | ||
| MDSTD

Metadata Standard
This is a citation of the metadata standard to which the metadata set conforms.
|
Citation | 1 | The values for MDSTD shall be MDSTD.title='urn:dgiwg:metadata:dmf:2.0:profile:all'and MDSTD.version='2.0' for the 'all' profile, MDSTD.title='urn:dgiwg:metadata:dmf:2.0:profile:core'and MDSTD.version='2.0' for the 'core' profile, or the values of one of the registered DMF Profiles: (MDSTD.title='urn:dgiwg:metadata:dmf:2.0:profile:<ProfileName>' and MDSTD.version='<ProfileVersion>'). | See citation.
metadataStandardName (respectively metadataStandardVersion) shall contain DMF (respectively 1.0) or the name (respectively the version) of one of the DMF registered profiles, e.g. STANAG 2586 (respectively Edition 1).
|
For backward compatibility use MDSTD.title='STANAG 2586' and MDSTD.version='Edition 1' for STANAG 2586 Edition 1. | urn:dgiwg:metadata:dmf:2.0:profile:all |

Metadata Security Constraint
This element provides a means to express a set of security constraints applicable to the metadata.
|
Security Constraint | 0..* | If the classification used is a national classification, ISO 3-letter code should be used for MDSCST.system | MDSCST.level = unclassified
MDSCST.system = NATO
or
MDSCST.level= Secret Défense
MDSCST.system = FRA

Metadata Releasability Addressee
This element establishes a body to which the metadata can be released.
|
String
|
0..* | The security constraints may appear before or after the releasability constraints. | To be compatible with NATO requirements, the String value should be an ISO 3-letter code. | GBR,FRA,DEU
NATO

Metadata Legal Constraint

Metadata Maintenance Frequency
This element provides information on the frequency with which changes and additions are made to the metadata after the initial metadata is completed.
|
Frequency Codelist | 0..1 |
| DMF/Core | DMF/Core defines the minimum set of metadata elements to be implemented by any metadata catalogue. This set satisfies the discovery use case. |
| DMF/Common | DMF/Common is an additional set of metadata elements for a more complete description of any type of resource supported by DMF. It extends DMF/Core and covers discovery and basic evaluation use cases. |
| DMF/Defence | DMF/Defence extends DMF/Core or DMF/Common for military oriented needs including NATO needs (extensions defined in NGMP, particularly security). It is needed to handle metadata to be exchanged with NATO in conformance with NGMP. DMF/Defence can be implemented with DMF/Core and possibly any other metadata class. |
| DMF/Specific | DMF/Specific is an extension of the ISO metadata standards for high level military implementation of the DMF metadata elements. |
