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

etc. Audio files Video files Learning Objects Reformatted

digital library collections

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
