1. Multiple Repository Integration
Case Study
Jim Martino
The Johns Hopkins University

2. JHU Repositories
• JShare (Xythos) - “online service that allows
students, faculty, and staff, and to share
files within and outside the university
community.”
• JScholarship (DSpace 1.5) - “is designed to
gather, distribute, and preserve digital
materials related to the Johns Hopkins
research and instructional mission.
• Data Conservancy (Fedora) – pending NSF
DataNet project for data curation.
July 2009 10th Sakai Conference - Boston, MA, U.S.A. 2

3. JShare
• Selective access, group management
• Integration target as a general content
source, specific storage destination
• No workflow for storage

4. JScholarship
• Institutional repository
• Integration target as a general
content source
• Submission has its own workflow

5. DataNet
The goal of the NSF DataNet
program is to create “a set of
exemplar national and global data
research infrastructure organizations
(dubbed DataNet Partners) that
provide unique opportunities to
communities of researchers to
advance science and/or engineering
research and learning.”

6. Data Conservancy
• The overarching goal of DC is to
support new forms of inquiry and
learning to meet these
challenges through the creation,
implementation, and sustained
management of an integrated
and comprehensive data
curation strategy.

7. Data Conservancy
Within a year ...
• we will have a large data set in
our repository
• we will demonstrate
interoperability between the
repository and a teaching and
learning environment (Sakai)

8. Data Conservancy
• Large data sets will change how
users access data
• Integration for use in teaching and
learning may require flexible
access control framework

9. Current examples
• Sakaibrary metasearch integration
is an interesting model of a
mediating system bundling access
to various diverse content
services
• SoftChalk integration feels a lot
like the Sakaibrary approach

10. Future Directions
Content Hosting Service and
Content Hosting Handlers will
likely not be available in K2
What technologies might be
available toreplace this method
of repository integration?

11. JCR Connect
JCR Tools For Sharing Content Between Open
Source Applications and Dissimilar
Repositories
Funded by the Mellon Foundation
Northwestern University
UCOP California Digital Library
FEDORA Commons
Chicago History Museum

12. JCR Connect
Project goal is to “develop software
modules that will create
interoperability between key open
source educational and scholarly
applications using JCR as a core
content exchange mechanism.”

13. JCR Connect

14. JBoss DNA
“JCR implementation that provides
access to content stored in many
different kinds of systems”
URL: http://www.jboss.org/dna/

15. JBoss DNA features
• Use the JCR API to access your repositories
• Manage numerous types of software assets,
artifacts, and components
• Sequencers that automatically help you unlock
information buried within files
• Connectors to access and integrate information
from file systems, repositories, databases, and
services
• Federate content from multiple connectors into a
single, unified JCR repository
• REST server for use by other services and client
applications
