Core Metadata

What is Emory Core Metadata?

As a result of the Metadata Working Group's 2014 research, standards benchmarking, and system profiling, we identified 18 core descriptive metadata fields (Emory Core) that are required or recommended for digital collections and projects. These core elements are:

  • Critical to end-user discovery and access
  • Commonly required in relevant metadata standards
  • Frequently utilized in Emory discovery interfaces (search, sort, browse, facet)
  • Broadly applicable to Emory content types
  • Schema-agnostic; mapped to established metadata standards

These guidelines are developed with final review and approval by the Emory University Libraries Cabinet. While additional metadata is encouraged and is required in some scenarios, Core metadata represents the minimum required to support search and discovery.
