Questions

The data dictionary then defines for both the user and the submitter the
necessary metadata fields, as well as the data that should be present. In the
case of this sample collection, one can see that a number of Dublin Core
elements have been repeated, but each element has a specific meaning within
the data dictionary. Moreover, utilizing this data dictionary, a DTD can be
created to give programmers within the library the ability to easily interpret
the metadata from this collection.
