Overview
1.Organisational objectives: current status
2. Example of digital curation in practice
Organisational objectives: current status
• Current digital curation practices focused on supporting the e-Science/e-Research support framework on campus
• Acknowledge the fact that digital curation is more than just ingesting, preserving and disseminating research output
• Started experimenting with replication technology – LOCKSS
• Institutional Repository (IR) will interface with Research Management System (RIMS) – SA RIMS (InfoEd) project
• Dspace RIMS interaction via Staging Area needs attention
Organisational objectives: current status
• Library Service, Dept of Research Development and the Dept of Information Technology: policy framework
• Institutional policies need to be in place• Human Resources: no dedicated
programmers, no dedicated repository administrator, no dedicated systems administrator, 2 part time staff, no real budget

Implementation - technology plan
• Dspace digital repository system• Standardize on version 1.5 for 3 years• Need to workshop OAIS framework (in
South African context)• Full OAIS-compliance in Dspace Release
2• Replication of ETD’s with LOCKSS – Proof
of Concept planned for 2009• Some work done with LOCKSS on format
migration• Multiple instances of Dspace – more
flexibility, more personalization
Implementation – virtual server setup
