Evaluating Your DPN Metadata Approach

Evaluating Your DPN Metadata Approach.  DPN Preservation Metadata Standards Working Group. July 27, 2017. [PDF, 6 pp.]
     This brief guide can help determine a clear metadata approach to recovering data "in the far future among unpredictable circumstances".  The document can help users create a sound approach to preserving your institution’s data and make decisions that fit with their own institutional needs.

The first section is:
What information is needed to understand and contextualize an object? It examines both descriptive and structural metadata.

Descriptive Metadata: for the purpose of identification and discovery of an object. Dublin
Core, MODS and VRAcore are common standards used for descriptive metadata.  

Structural Metadata: describes relationships between objects, such as pages in a book. The METS Structural Map can express  hierarchical relationships or parent/child relationships. The PREMIS "relationship" element can express version relationships.

The document also looks at how to:
  • understand and contextualize a collection; 
  • connect/relate objects to a collection; 
  • connect/relate versions to each other; 
  • connect metadata records to associated objects and collections;
  • ensuring the authenticity of an object;
  • ensuring the essential characteristics of the original are maintained in a data migration
