Institutional repositories are digital collections that preserve and provide access to a university's research output. They allow for long-term preservation of works and open access to scholarly articles, data, and other materials. Content is ingested through a submission process, preserved in a bitstream format, and disseminated through search and browsing. Institutional repositories differ from traditional databases in their use of bitstream storage and workflows. Common repository software includes DSpace and EPrints, which provide features like metadata collection, document archiving, and usage statistics. However, challenges exist in gaining contributor support and addressing intellectual property issues.

3. Introduction
• Institutional repositories are digital collections
capturing and preserving the intellectual output
of a single or multi-university community. (Crow,
2002).
Institutional Repository
• A collection of (digital) objects, in a variety of
formats
• Scholarly output of an Institution
3

4. Motivation
• Long term Preservation
• Open Access
Institutional Repository
• A place for the storage and retrieval of informal
publications, datasets, technical reports, course
materials, etc.

5. How an IR Works
• Three Common steps involved
1. Data Ingestion
Institutional Repository
2. Data Preservation
3. Data Dissemination
5

6. Data ingestion
• The process of adding digital documents to the
institutional repository, along with Meta Data.
• Example: Ingestion in Cornell IR
• User Registration and Authentication
Institutional Repository
• Document Uploading
• Licensing
6

7. Data Preservation
• Storing the Digital Material in a Bit Stream
format to Preserve it for a longer time.
• Example: Preservation in Cornell IR
Institutional Repository
• Document Archiving
• Data Preservation support
• Administration

8. Data Dissemination
• Exhibiting the bit stream content in a proper
digital document form. The method through
which users can access digital material in IR.
Institutional Repository
• Example: Dissemination in Cornell IR
• Searching and Browsing
• Management of Search Rights

10. Difference From Traditional
Databases
• Bit Stream storage along with a relational Database
• Usually involves a workflow
Institutional Repository
• Example software
• Dspace
• Eprints
• Fedora
10

11. IR Software:Dspace
• Web Base System
• Involves a workflow
• Allows one or more human reviewers or 'gatekeepers' to check
over the submission and ensure it is suitable for inclusion in the
Institutional Repository
collection.
• Meta Data correction by Administrators
• Bit Stream file storage on the server with PostgreSQL or
Oracle as Database
11

12. IR Software:Dspace…
• Searching and browsing
• one or more keywords in metadata or extracted full-
text
• Browsing through title, author, date
Institutional Repository
• OpenURL Support
• Item, Collection and Community Usage Statistics

14. Problems
• Not all potential contributors are enthusiastic
• Cost
• Software cost
• Cost of Required number of staff
Institutional Repository
• Cost of Preserving Data
• Intellectual Property Policies
• Mixed meta data problem
14

15. Conclusion
• We can develop a network of institutional repositories,
that presents every institutions intellectual work in
distributed manner.
• With the help of an IR an institution can show its
Institutional Repository
intellectual work to the world, which can be an indicator
to the quality of work done, thus increasing its status
visibility and value.
