been operating since 2000 and its over-
all mission is to improve ways of dissemi-
nating the research results of researchers
and students based at Uppsala University.
Issues related to long-term access and pres-
ervation of documents stored digitally are
another part of its mission, as well as serv-
ing as a knowledge centre within the uni-
versity. Staff at EPC also assist other projects
related to the digital library in such issues as
interoperability and standards, usability, and
compatibility between the various technical
solutions used.
D
iVA was the very first project realised
within the Centre and its objectives
include the development of generalised
technical solutions and workflows support-
ing full text publishing, storage, and dissem-
ination of locally produced documents. The
tasks of exploring methods for ensuring
access, and using and understanding digital
objects into the future, were also part of the
project team's assignments.
THE DIVA PUBLISHING SYSTEM
T
he DiVA publishing system was devel-
oped with a focus on how to achieve
rational and convenient publishing work-
flows for both authors and administrative staff
working in the publishing process and simul-
taneously increase efficiency and reduce costs.
A significant effort has been made to develop
practical solutions to support longevity of the
electronic documents and to ensure access in
the long term. The resulting workflows are
based on the reuse, in many different contexts,
of the structured information originally cre-
ated by authors. From a system architecture
point of view, DiVA is built using a compo-
nent-based design methodology; components
can be reused in a different context, and also
seamlessly replaced with improved versions.
The system is based on current standards and
recommendations and is implemented using
Java and XML technologies.
Current functionality
The DiVA Publishing System makes it pos-
sible to:
reuse and enhance data from source doc-
uments originally created by authors
both the digital master for electronic and
printed versions, and its associated meta-
data;
convert all metadata and (if possible)
contents of the documents to a uni-
form XML-based format (the DiVA
Document Format);
assign a persistent identifier, checksum
all files, and store them in a local reposi-
tory (and an additional copy in the local
archive);
send a copy accompanied by metada-
ta and bundled into an Information
Package to the national library archives;
disseminate metadata (e.g. OAI-MHP,
catalogue records in MARC, or RSS
feed);
search and browse all items through a
local user interface;
search and browse all items through the
federate search interface the DiVA-
portal;
manage the system through an adminis-
trative interface.
A
s mentioned earlier, the metadata and,
in an increasing number of cases, even
the content of the document are stored in
XML. In order to support this a local doc-
ument format was developed the DiVA
document format (DDF).
