overview
Digital Case opened for business on August 22,
2006 Digital Case is Case Western Reserve
University's digital library, repository and
archive Digital Case stores, disseminates, and
preserves the intellectual output of Case
faculty, departments and research centers in
digital formats (both "born digital" items as
well as materials of historical interest that
have been digitized) Digital Case has over
10,000 items of content organized into 13
collections Users across the globe have accessed
Digital Case items over 13,000 times and
conducted over 12,000 search queries Digital
Case promotes Open Access through OAI-PMH and
Google Sitemaps

process
Institutional Repositories (IR) are technical in
nature and technical staff typically drive the
process Kelvin Smith Library (KSL) realized
early on that user interface design is not our
forte and we would need professional help with
that effort Given the importance of Digital Case
to the University and the KSL, we knew that the
user interface needed to be the best of breed in
this space Hired Optiem, a local technology and
design firm to lead the design process allowing
KSL resources to focus on the business
requirements and implementation Optiem realized
potential synergies at the outset between Ektron
and Fedora Started the process by asking our
users what they would envision a digital library
to be

digital case
Designed to collect and preserve digital content
produced by Case Western faculty and
staff Needed to make these vast collections
accessible to researchers and the world at
large via a simple and intuitive interface
10
browse
Browsing the Collections was designed to aid a
visitor by giving them easy access to
sorting and filtering items Visitors are able to
sort alphabetically or restrict by format They
may peruse through a collection with access to
Title, Creator, Date, a permanent URL and a
summary describing each item
11
search

• The Search employs an optimized
• system powered by Lucene
• Visitors can search by
• Key Word Combinations
• Digital Asset Format
• Collection or Collections

examine
Viewing individual pieces of content often
involved images. The JPEG 2000 server was used
to dynamically serve images in the size needed
by the requester Video content is served as
Flash video, employing the same technology as
You Tube and Google Video and providing for
cross browser compatibility
13
admin interface
The Admin Interface bridges the management of
both Digital and Website content Utilizing
LDAP, any Faculty member is able to submit
content, while KSL Librarians control what
content gets published Content Added is
intuitively organized in a folder structure for
easy access
14
images and files
Ektrons Library was already designed to provide
an interface for uploading and organizing files
and images The Drag and Drop multiple file
upload system provides a convenient and easy way
to move a collection of files or images,
including a Dublin core Record from the users
local machine to the server
15
smart forms
Ektron Smart Forms were used as the interface for
Objects and Data Streams Smart Form data is
stored as XML in the Ektron Database The Dublin
Core Record, the Object Info and any Data Streams
are all stored as XML data in the Smart Form
16
extensibility server
The Ektron Extensibility Server provided the
event hook functionality around which Fedora
Interfacing could take place based on the
editing, addition and publishing of CMS
content XML parsing in ASP.NET facilitated the
communication needed to translate Smart Form
content into FOXML Web Services in Ektron
allowed us to dynamically add Smart Form content
based the items dragged into the System
17
custom development
After translation of the content was complete,
calls to the Fedora API-M service allowed us to
add content to Fedora Web Services were employed
to convert Images and video to JPEG2000 and Flash
video formats, while a call to the indexing
service ensured that Lucene would detect the
addition of new items Successful addition of
content allowed for the deletion of the uploaded
content, keeping only the reference info in Ektron
