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)
![Page 12: DIGITAL ARCHIVES](https://reader034.vdocument.in/reader034/viewer/2022051416/568145ef550346895db2f3a8/html5/thumbnails/12.jpg)
Metadata
What is it and why is it important?
![Page 13: DIGITAL ARCHIVES](https://reader034.vdocument.in/reader034/viewer/2022051416/568145ef550346895db2f3a8/html5/thumbnails/13.jpg)

Descriptive Metadata
Data that describes the digital object such as a bibliographic record or finding aid, i.e. MARC record
![Page 14: DIGITAL ARCHIVES](https://reader034.vdocument.in/reader034/viewer/2022051416/568145ef550346895db2f3a8/html5/thumbnails/14.jpg)

Structural Metadata
Represents the relationship between multiparts objects, i.e. chapters of a book
![Page 15: DIGITAL ARCHIVES](https://reader034.vdocument.in/reader034/viewer/2022051416/568145ef550346895db2f3a8/html5/thumbnails/15.jpg)

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.

What We Are Using
Archival Collections - Encoded Archival Description (EAD)
Books, Journals, Photographs, etc. – Dublin Core
Metadata Encoding and Transmission Standard - METS

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
