What Is Descriptive Metadata, and Why Is It Important?
This session will be an overview of descriptive metadata, i.e., the type of metadata designed to facilitate discovery of digital
resources. Metadata standards such as MARC, EAD, CDWA, VRA Core, and Dublin Core will be discussed, as will the controlled vocabularies (LCSH, LCNAF, AAT, TGN, etc.) that are essential for populating metadata elements if they are to be truly effective. The importance of metadata mapping and "crosswalks" will also be discussed. The session will be illustrated with examples of implementations of descriptive metadata standards and controlled vocabularies and how they are being used or misused, and the benefits of filling metadata "containers" with appropriate vocabulary values.
