Key elements of the DCC Curation
Lifecycle Model
Key elements of the DCC Curation
Lifecycle Model
• Data
• any information in binary digital form, is at the
centre of the Curation Lifecycle.

Case Study
The Eastern North Carolina
Digital Library
The Eastern North Carolina Digital
Library: the 4 W’s
Who:
• Joyner Library at East Carolina
University+
What:
• A digital library of books+ about eastern
North Carolina
When:
• 2003-2004, initial project
• 2004-2007, partnership project
The Eastern North Carolina Digital
Library: the 4 W’s
Where:
You are
here.
The Eastern North Carolina Digital
Library: the 4 W’s
Why:
• ECU is the largest university in the eastern
region, serving some of the poorest and
most under-served counties in the state.
• Material on eastern NC not widely
available
• The expertise and interest existed in the
library to create a great digital project.

…until
Case Study: The Eastern North
Carolina Digital Library
• 2008-2009, creation of Joyner Library
Digital Collections, a sister repository more
broad in scope
• 2010-2011, migration of ENCDL into JLDC
Comparing
ENCDL
JLDC
• TextML / ASP.net
• Non-standard metadata (aside
from TEI transcriptions)
• Two basic material types
• Non-standard filenaming
• Significant supplementary
documentation for each object
• Text and Image/artifact in
different search and browse
• Extensive web-presence with
educational activities
• TextML / ASP.net
• Metadata standards (METS,
MODS, MIX, TEI)
• Variety of materials
• Each object has Persistent
Identifier (PID) and consistent
filenaming
• Full-repository search
• Basic web-presence, but
robust searching tools
Digital Curation
Round One…
Applying the lifecycle model
• Community Watch and Participation
– What are the common standards endorsed by our
community?
•
•
•
•
•
•
JPEG2000
EPUB
PREMIS
NC ECHO’s PMDO
Flash
HTML 5
• Curate and Preserve
– What are the standards that
will best fit our curation and
preservation needs?
Applying the lifecycle model
• Preservation Planning
– What actions are in the best long-term interest
of the ENCDL? JLDC?
• Meetings with
stakeholders
• Web analytics
• Reproduction requests
• Review of infrastructure
• Migration
– Digital objects, metadata,
web application
Applying the lifecycle model
• Create a new collection in the repository
• Create a “PID” for each digital object into the repository
• Create METS/MODS/MIX/TEI/PREMIS record for each
– Incorporate supplemental metadata
– Create new PREMIS records for each
• Create new hybrid object type
for image + video
• JPEG2000 for all images
• pdf and epub for books
Applying the lifecycle model
• JPEG2000
– Complicated algorithms
– Inadequate software
– Web application development with Kakadu
– Presentation copies only at this time.
• Metadata
– PREMIS
– Mapping and scripting multiple times
• Repository structure
– Modeling new object types
– Functional requirements for UI
and metadata
– Use case scenarios in ENCDL
mapped to JLDC
Applying the lifecycle model
• Access, Use and Reuse
– Recreate the book viewer using JPEG2000
– Create subject and map browse for the entire
repository
– Recreate ENCDL pages
with repository’s
stylesheet
The End
• Curation
• Preservation
• Community Watch
and participation
What Have We Learned?
• Many of us will eventually need to migrate not
just data, but collections and “experiences”
into other repositories.
• Digital Curation Lifecycle Model can help us
think through Curation activities and evaluate
them.
• The Lifecycle Model is not linear, nor will our
activities be.
• The Lifecycle Model is not finite, but iterative.
Thanks!
