Do not confuse with:
DATE METADATA MODIFIED: the date, or date and time, on which an Open Government Portal catalogue record is changed.
In the Open Government Portal context, DATE MODIFIED refers to the last date on which the content of an information resource revised. The date of the most recent update is the only date retained.
In the case of records which describe an information resource with more than one items (files) attached to the record, such as serial resources or resources with more than one part (eg. book chapters), the DATE MODIFIED should be changed when the content of one or more of the described resources is changed, or when new issues or new parts of the resource are added.
For most publications and many other information resources in the Portal, the DATE CREATED and DATE MODIFIED will be the same and will likely remain the same.
