Session GoalSession Goal
Workshop participants will be able to produce technical, administrative, and descriptive metadata about the digital
objects.

Session ObjectivesSession Objectives
Overview big picture metadata issuesOverview technical, administrative,
preservation, and descriptive metadataFamiliarize learners with project
documents for metadata creationIllustrate the metadata creation process
involving technical, administrative, and descriptive metadata in a Hands-on Lab

Learner OutcomesLearner Outcomes
Understand different types of metadata and their uses
Recognize the necessary documentation used to produce tech, admin, and descriptive metadata
Use CONTENTdm Acquisition Station in order to add descriptive to digital images
Name and Save a TIFF, TXT transcript, and PDF onto computer HD using standard naming convention

Digital Objects RecommendationsDigital Objects Recommendations
CONTENTdm does much of the metadata work for us
Recommended: Excel worksheet◦File names, scanner, date, item filed, etc.
File naming conventions

Data standardsData standards
What do you need to describe a resource? To help researchers find it? To know who created it?
Data structure standards◦Specifies the elements that should be included◦Examples: MARC, MODS, EAD, VRA Core, CDWA

CONTENTdm provides a descriptive framework using Dublin Core and tools for the creation of◦Compound objects (multi-sided or multi-level
documents that use the same metadata)◦Tools to edit metadata field names that can
then be linked to Dublin Core records
