dc:Source

This field will always identify the paper publication from which this digital object was derived, including information such as Journal Title, Volume, Page Number, etc. For a digital object for which multiple alternate formats/types is available, this field may also refer to a digital authoritative original from which this object is derived.

dc:Subject

This field will always contain a key word, phrase, or code from a controlled vocabulary which describes the object.

dc:Title
