2. 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
3. Digital Preservation
Philosophy
Lots
of digital material is already lost
Most digital material is at risk
Better to have it, do bit preservation than to lose it
completely
Need to capture as much information as possible
to support functional preservation
Cost/benefit tradeoffs
4. {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.

12. 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)

17. 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
18. 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
19. E-Groups
DSpace calls the reviewers, metadata
editors, collection administrators as E-groups
It means, there can be more than one eperson (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
