Metadata - resourceConstraints

Implementation notes about gmd:resourceConstraints parsing.

Principles

• identificationInfo[1]/*/resourceConstraints provides different categories of constraints applicable to the resource (or its metadata)
• Each resourceConstraints contains either a MD_Constraints, a MD_LegalConstraints or a MD_SecurityConstraints

Constraint types

Type	Description
MD_Constraints	Restrictions on the access and use of a dataset or metadata.
MD_LegalConstraints	Subclass of MD_Constraints describing restrictions and legal prerequisites for accessing and using the dataset.
MD_SecurityConstraints	Subclass of MD_Constraints handling restrictions imposed on the dataset because of national security, privacy, or other concerns

Attributes for each constraint type

MD_RestrictionCode

• copyright
• patent
• patentPending
• trademark
• license
• intellectualPropertyRights

• otherRestrictions

MD_ClassificationCode

• unclassified
• restricted
• confidential
• secret
• topSecret

Limitations on public access

• identificationInfo[1]/*/resourceConstraints/*/accessConstraints : MD_RestrictionCode (ex : intellectualPropertyRights)
• identificationInfo[1]/*/resourceConstraints/*/otherConstraints : Free text
• identificationInfo[1]/*/resourceConstraints/*/classification : MD_ClassificationCode (ex : restricted)

Quotes from TODO_REF :

• “The value of accessConstraints is otherRestrictions, if and only if they are instances of otherConstraints expressing limitations on public access”

Condition applying to access and use

• identificationInfo[1]/*/resourceConstraints/*/useLimitation
