Limitations on public access: access

Name Limitations on public access: access
Definition Access limitations are applied to ensure the protection of privacy or intellectual rights, or any other impediments or restrictions to access data resource.
Obligation
  • dataset or dataset series: mandatory
  • service: mandatory
Multiplicity [1..*] for accessConstraints per each MD_LegalConstraints instance
Example other restrictions
Only one instance of this element is required, which must have a code list value "other constraints".

Implementation instructions This metadata element provides information about limitations on public access to data and the reasons why they occur. Article 13 of Directive 2007/2/EC prescribes the cases in which public access to a spatial data source may be limited. Public access to spatial data sources through the discovery service may be limited if such access could adversely affect international relations, national security and national defense. Public access to spatial data sources through view, download, transformation and invoke services or e-commerce services may be limited if such access could adversely affect one of Article 13 (a) (h) of Directive 2007/2/EC.

At least one reason must be documented as a limitation on public access or in case there are no limitations, to emphasize this fact, in such a way that the element gmd:resourceConstraints/gmd: MD_LegalConstraints includes:
 
  • one instance of the gmd:accessConstraints/gmd:MD_RestrictionCode element containing the value of other restrictions ("otherRestrictions" XML value) of the ISO 19139 code list MD_RestrictionCode (Limitations on public access: access) and
  • one or more instances of the gmd:otherConstraints element (Limitations on public access: other restrictions), depending on the number of reasons, using the gmx:Anchor element to state the appropriate reason and reference the definition of the same.
    • The reasons which may be given in the element are the reason in point (a) or the reasons in points (c) to (h) defined in Article 13 (1) of Directive 2007/2/EC which have been cited above. To refer to them, it is necessary to use the LimitationsOnPublicAccess INSPIRE code list. In addition to the reasons for limitations on public access, this code list also contains an expression that defines that there are no limitations ("noLimitations" XML value) that needs to be specified in case when there are no limitations on public access to the spatial data source.
    • In the xlink:href attribute of the gmx:Anchor element, a link to the appropriate code list value needs to be specified, and the content of the element can be the name or definition of the code list value in the metadata language (see coding example).
