• Ingesting digital objects into The UNZA’s IR is
challenging
– Ingestion is time consuming due to the complex ingestion
workflows
– There is a backlog of digital content not yet ingested

10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors
Research Objectives
• The main objective of this study was to investigate the
feasibility of using subject institutional repositories for
ingesting digital objects
– To what extent is scholarly research output visible via the
institutional repository?
– What is the feasibility of implementing a subject repository as
part of an institutional repository ingestion workflow?
– What is the perceived usability of a subject institutional
repository?
• Main contributions of this work
– Evaluating IR ingestion practices, using a content analysis
approach of IR digital objects
– Results from usability studies conducted to determine the
outcome of using subject repositories
– Demonstration of the feasibility and efficacy of using subject
repositories

Research Approach (1/4)
The study employed a mixed methods approach that
involved undertaking a situational analysis, in order to
understand the current state of the problem and,
implementation and subsequent evaluation of a subject
institutional repository
1. Content analysis of repository objects
2. Interview sessions aimed at understanding the
ingestion workflow
3. Implementation of subject institutional repository
4. Usability evaluation of subject institutional repository
10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors
Research Approach (2/4)
• Content analysis
– Dublin core descriptive metadata harvested using the
OAI-PMH protocol
– Metadata elements analysed
• Interviews with staff responsible for ingestion of
digital objects

Conclusion and Outlook
• A case study aimed at assessing the feasibility of
using subject IRs for facilitating effective ingestion of
digital content
– Empirical analysis of digital objects ingested into The UNZA
IR demonstrates the extent of these challenges.
– Implementation and usability evaluation of the subject IR
demonstrates the feasibility of implementing usable subject
IRs
• The obvious benefits of subject IRs is that
self-archiving is decentralised, making it relatively
easier for research output to be made available online
– HEIs are better placed to ensure that research output is made
available in IRs in a timely manner

  • 17. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Research Objectives • The main objective of this study was to investigate the feasibility of using subject institutional repositories for ingesting digital objects – To what extent is scholarly research output visible via the institutional repository? – What is the feasibility of implementing a subject repository as part of an institutional repository ingestion workflow? – What is the perceived usability of a subject institutional repository? • Main contributions of this work – Evaluating IR ingestion practices, using a content analysis approach of IR digital objects – Results from usability studies conducted to determine the outcome of using subject repositories – Demonstration of the feasibility and efficacy of using subject repositories
  • 18. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Research Approach (1/4) The study employed a mixed methods approach that involved undertaking a situational analysis, in order to understand the current state of the problem and, implementation and subsequent evaluation of a subject institutional repository 1. Content analysis of repository objects 2. Interview sessions aimed at understanding the ingestion workflow 3. Implementation of subject institutional repository 4. Usability evaluation of subject institutional repository
  • 19. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Research Approach (2/4) • Content analysis – Dublin core descriptive metadata harvested using the OAI-PMH protocol – Metadata elements analysed • Interviews with staff responsible for ingestion of digital objects

  • 26. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Major Outcomes/Results (3/4)
  • 27. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Major Outcomes/Results (3/4) ● Ingestion of digital content is not done in a timely manner, compromising the recency of digital content ● Backlog of legacy content not yet uploaded
  • 28. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Major Outcomes/Results (4/4) ● Overall, acceptable SUS score
  • 29. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Major Outcomes/Results (4/4) ● Overall, acceptable SUS score supported by reasonably “Good” adjective rating
  • 30. 10 - 14 May 2021 IST-Africa 2021 Copyright 2021 Authors Conclusion and Outlook • A case study aimed at assessing the feasibility of using subject IRs for facilitating effective ingestion of digital content – Empirical analysis of digital objects ingested into The UNZA IR demonstrates the extent of these challenges. – Implementation and usability evaluation of the subject IR demonstrates the feasibility of implementing usable subject IRs • The obvious benefits of subject IRs is that self-archiving is decentralised, making it relatively easier for research output to be made available online – HEIs are better placed to ensure that research output is made available in IRs in a timely manner
