Digital Preservation
“Preservation is a critical function for any institutional repository, as organizations both large and small realize the need for built-in digital preservation tools to ensure access, storage, and management for the long-term. DSpace fulfills that responsibility admirably. The choice of which better suits an institution depends on its resources, technology support, and desire to have a heavily customizable or out-of the box solution to institutional repository and preservation needs.” -Lisa Phillips
Digital Preservation
Philosophy Lots of digital material is already lost Most digital material is at risk Better to have it, do bit preservation than t
o lose it completely Need to capture as much information as
possible to support functional preservation Cost/benefit tradeoffs
{Electronic} e-Institutional Repository Vs Digital Library
Institutional Repository are organized around a particular Institutional community while Digital Library may be May be built around any number of organizing principles (often topic, subject, or discipline).
Institutional Repository are dependent upon the voluntary contribution of materials by scholars for the content in their collection while Digital Library are the product of a deliberate collection development policy
Institutional Repository are mainly repositories and therefore may only offer limited user services while Digital Library are typically include an important service aspect (reference and research assistance, interpretive content or special resources).
A repository makes the intellectual output of an organization (or multiple organizations or just one department) freely and openly available. A digital library on the other hand, is a gateway to electronic resources including but not limited to: an OPAC (Online Public Access Catalogue), ebooks, ejournals (usually subscription based), bibliographic databases (e.g. CINAHL, MEDLINE, PsycINFO, Embase, Cochrane Library, Web of Science - depending on your subject areas) and citation management tools. It should also include access to online referencing and to a live librarian (real qualified person is good). I manage both a digital library and a repository so if you need more info, please contact me. It might be wise to start with a needs analysis of your clients.
What is DSpace
100% free open source software Based on JAVA (Web based /Web
archiving) Begin federation
Fall 2002 DSpace Foundation
First Developed by MIT and HPMIT first public release
October 3, 2002 &
Open Source to the world - DSpace 1.0 November 4, 2002
What is DSpace (Count…
Scalable (Means any grid support- hardware, Cloud)
Modular- like Joomla, Drupal, Moodle User Friendly Multi-user (including both searching and
maintenance) Multimedia digital object enabled Platform independent (including both
client and server components) interoperable
Federation Partners
Cambridge University (UK)

What DSpace can…
Captures Digital research material in various formats Directly from creators (e.g. faculty)
Describes Descriptive, technical, rights metadata
Distributes Via WWW, with necessary access control
Preserves type : Functional Preservation
DSpace Offering
Large-scale, stable, managed long-term storage
Support for range of digital formats depositing of multiples bite in one item Easy-to-use submission process Persistent network identifiers Access control Search and delivery interface Digital preservation services

Technology Stack
Apache- Maven, Tomcat, OpenSSL/mod_ssl
Java 1.3, JSP 1.2, Servlet 2.3 PostgreSQL 7, JDBC (rdbms) CNRI Handle System 5 (persistent ids) Lucene 1.2 (index/search) Jena (RDF History system) JUnit (testing), Log4j (logging) HP/UX, Linux, Solaris, etc.
Information Structure
“Community" is a grouping of collections and/or "Sub-communities“
“Collection" is a group of related items in an archive.
"Items" are records that describe the file(s) being archived, using the Dublin Core metadata scheme
"Bundle" is a grouping of files associated with an item
"Bitstreams" are the individual files grouped together in a bundle and associated with an item. (e.g. license text, jpegs, tiffs, pdfs, doc, xml)

Administering DSpace
Anonymous Users (anybody) Members, who wish to subscribe to a collection (one
can not subscribe to communities). Also called E-person in DSpace
Submitters (authors), who submit their publications to a collection (they should be members and have been authorized to submit).
Reviewers - members who are authorized to review submissions. They can either accept or reject submissions). Normally, they are subject specialists
Metadata Editors – who validate the metadata. Normally, they are library professionals
Administering DSpace (Count… Collection Administrators. In a large
digital repository collection administration can be delegated various E-groups.
They can choose the reviewers, metadata editors among members and decide the collection policy
They are different from DSpace administrators, who have the overall responsibility and power. A kind of super-user
E-Groups
DSpace calls the reviewers, metadata editors, collection administrators as E-groups
It means, there can be more than one e-person (member) in any list of reviewers or metadata editors etc.
Each e-group can be associated with one or more collections
A member can be placed in none or more than one e-group
