Metadata elements of constraints related to access and use specify a high level of data classification. They provide information to the user about any limitations to access and use of data resources. In setting constraints related to access and use, care must be taken to set specific values for data resources, because metadata are not meant to be repositories of knowledge about a particular right or a special form of licensing.
If there are detailed information or documents published about particular rights, links to the relevant document or information can be documented to help the user. Constraints related to access and use are expressed by means of the following:
Conditions of access and use
Public access limitations: access
Public access limitations: other restrictions
