Identifier Title / Description Value Domain Card Condition Metadata classses Guidelines Example
RSSCST
[DMF/Core]
Resource Security Constraint
This element provides a means to express a set of security constraints applicable to the resource
Security Constraint 0..*   DMF/Core defines the minimum set of metadata elements to be implemented by any metadata catalogue. This set satisfies the discovery use case. If the classification used is a national classification, ISO 3-letter code should be used for MDSCST.system  MDSCST.level = unclassified  
RSREL
[DMF/Defence]
Resource Releasability
This element provides a means to express a set of releasability information applicable to the resource.
Releasability 0..*   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. To be compatible with NATO requirements, the String value should be an ISO 3-letter code. GBR,FRA,DEU  
RSUSE
[DMF/Core]
Resource Use Limitation
This element provides a means to express general use limitations (limitations not implied by security or legal constraints) of the resource.
Free Text 0..*   DMF/Core defines the minimum set of metadata elements to be implemented by any metadata catalogue. This set satisfies the discovery use case. Standardized phrases could be considered based on known products and/or output. Defence purposes only
RSLCST
[DMF/Core]
Resource Legal Constraint
This element provides a means to express a set of legal constraints applicable to the resource.
Legal Constraint 0..*   DMF/Core defines the minimum set of metadata elements to be implemented by any metadata catalogue. This set satisfies the discovery use case.   restricted
