Use of Standards

Metadata Creation – EAD, Dublin Core, etc

Imaging – 600 DPI, 8 Bit Greyscale, 24 Bit Color

OCR – ASCII Text

Data Structure – Metadata Encoding and Transmission Standard (METS)

Metadata

What is it and why is it important?

Gabrielle V. Michalek, Carnegie Mellon University

Descriptive Metadata

Data that describes the digital object such as a bibliographic record or finding aid, i.e. MARC record

Gabrielle V. Michalek, Carnegie Mellon University

Structural Metadata

Represents the relationship between multiparts objects, i.e. chapters of a book

Gabrielle V. Michalek, Carnegie Mellon University

Administrative Metadata

“Data that supports the unique identification, maintenance, and archiving of digital objects, as well as related functions of the organization managing the repository”, i.e.who created this object, which software, version was used, etc.

Gabrielle V. Michalek, Carnegie Mellon University

What We Are Using

Archival Collections - Encoded Archival Description (EAD)

Books, Journals, Photographs, etc. – Dublin Core

METS Incorporates descriptive, structural, and

administrative metadata

Allows you to bind heterogeneous collections together and show relationships between information

Becomes a wrapper for the collection
