The presentation was given at the Delos Summer School (Tirrenia, June 2008). This presentation provides an overview of digital repositories, looking at different repository types and dividing them by content type, coverage, functionality and target user group. It concludes with two group exercises, one writing a use case for a web archiving project and the other a business case for sustained funding for an Institutional Repository beyond its start-up phase, to help apply knowledge to real-world situations.

What is a repository?Content is deposited in a repository, whether by the content creator, owner or third partyRepository architecture manages content as well as metadataRepository offers a minimum set of basic services (put, get, search, access control)Repository must be sustainable and trusted, well-supported and well-managed

Heery and Anderson, Digital repositories review 2005

Open Access repositoriesRepository must provide open access to its content (unless there are legal constraints)

Repository must provide open access to its metadata for harvesting

Not all repositories are OA repositories

Core requirements for digital archives -1Commitment to digital object

maintenance

Organisational fitness

Legal and contractual rights

Effective and efficient policies

Acquisition and ingest criteria

Core requirements for digital archives -2Integrity, authenticity and usability

Provenance

Dissemination

Preservation planning and action

Adequate technical infrastructure

Context

Wider information environment

Corporate management systems

Content creation workflows

Personal information environment of users

Services built on repository content

Page 8: Repository models: from experimentation to services

8

Types of repositories

By content type

By coverage

By functionality

By target user group

Page 9: Repository models: from experimentation to services

Content types

Raw research data

Derived research data

Pre-prints

Post-prints

E-theses

Technical reports

Learning objects

Corporate records

Coverage

Personal (author’s personal archive)

Journal (single or group)

Departmental

Institutional [IR]

Inter-institutional (regional, collaborative, economies of scale)

National

international

Page 11: Repository models: from experimentation to services

Functionality

Enhanced access to resources (resource discovery)

Subject access to resources

New modes of dissemination

Institutional asset management

Sharing and re-use of resources

Digital preservation

Page 12: Repository models: from experimentation to services

Target user group

Learners

Teachers

Researchers

Administrators

Regulators

General public

Can you think of other user groups served by existing repositories?

OAIS

Does a repository have to conform to or otherwise follow OAIS (ISO 14721)?

A national election is called!Web archiving project

Dark archive, dissemination issues later

Rights issues already fixed

Funding has already been found

Write a use case

Page 17: Repository models: from experimentation to services

Use case

Summary

Actors and goals – people and what they want to achieve

Stakeholders and interests

Main success scenario

Page 18: Repository models: from experimentation to services

Sustaining an Institutional RepositoryMedium-large university

Active research and teaching

Integrated library and IT function

Start up was externally funded

Deliver a business case to the Principal
