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.

Key elements of the DCC Curation Lifecycle Model

• Full Lifecycle Actions– Description and Representation

Information– Preservation Planning– Community Watch and Participation– Curate and Preserve

Key elements of the DCC Curation Lifecycle Model

• Sequential Actions– Conceptualise– Create or Receive– Appraise and Select– Ingest– Preservation Action– Store– Access, Use and Reuse– Transform

Key elements of the DCC Curation Lifecycle Model

• Occasional Actions– Dispose– Reappraise–Migrate

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 CarolinaWhen:• 2003-2004, initial project• 2004-2007, partnership project

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.

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• 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

JLDC• 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?

• 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

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!
