Metadata is information about Data
“Descriptive metadata helps users find and obtain objects, distinguish one object or group of objects from one another, and discover the subject or contents.” – NISO Framework of Guidance for Building Good Digital Collections
If you do your own collection, this is the primary type of metadata you’ll create.

MLA
Now we’ll do a “crosswalk”
• A crosswalk is a matrix that allows you to look at the data fields you have and match them as best you can to an existing standard.
• We are going to see how MLA fits into the Dublin Core of 15 basic terms.
MLA vs Dublin Core
Inventing Metadata Fields
• Metadata concepts for a project rarely match perfectly to a standard.
• Some standards allow you to combine concepts – a metadata mashup.
• Sometimes you need to add special fields that are
outside the standard.
• User need is more important than a standard.
What is a Data Dictionary?
• A Data Dictionary lists terms used, reasons for use, samples and context for use.
• Shared document that shows all involved parties the data fields.
• Reminds project participants of decisions made.
• Makes consistency in data entry possible.

Selecting Metadata Concepts Summary
• Find a role model• Construct a Crosswalk from the role model to the data in
use• Add in a few field concepts that the model doesn’t have• The resulting list of terms is the data dictionary.

Note differences between our model and our collection
Common Metadata Standards in the Humanities
• Dublin Core (Libraries and Museums)– http://www.bridges.state.mn.us/dcore.html
• Visual Resources Association (VRA and Museums)– http://www.vraweb.org/projects/vracore4/
• EAD aka Encoded Archival Description (Archives and Museums)
• MODS aka Metadata Object Description Schema (Library of Congress)
Tracking Rights in Metadata
• Consider your copyright message to users• Consider what permissions you’ve obtained and
how/if you wish to share them with your users• Consider where this information fits in with your
metadata scheme• Note that in Dublin Core, there is a Rights
concept
Next Steps
• Consider your audience• Find where you fit with other
collections• Find a role-model collection• Talk to your campus resources
about metadata
Data Curation and Content Selection
• Data Curation is in its infancy: processes and standards are being formed now
• Your campus may have a digital policy already in place, like the University of Utah– http://www.lib.utah.edu/collections/digital/

Project Afterlife
• Exit Strategy– Do you want your collection to live on?– Migration– Control over your content
• Creative Commons License– Define how you want others to use or re-use your
work– http://creativecommons.org/choose/
