What are the XML Schema or DTD declarations for each format?

 

A schema or DTD (Document Type Definition) describes the structure of an XML record as well as the relationship of the elements to the application. It must appear at the beginning of the first record of a file of records, or at the beginning of each record if a file contains only one record. Records without a schema or DTD will be rejected.

Below are the schema and DTDs for the three metadata formats that can be employed on AGRICOLA metadata records.
