Solutions Showcase:
DSpace
  • Scott E. Siddall
  • Denison University

In 2010…
  • Prospective students envision their major by browsing your institution’s Repository of Student Scholarship
  • Consortial faculty members share curricular and research materials because tools to catalog the content are effective
  • Your alums read selected contributions that are reviewed and assembled into a virtual journal of creativity and scholarship

Growth in digital content
  • In 200 years…
        • 29 million monographs
        • 2.7 million recordings
        • 12 million photographs
        • 4.8 million maps
        • 57 million manuscripts
  • Today, globally, this volume of digital data is produced each 15 minutes


  • 40% of our time spent searching; 70% of content is created anew


    • [Center for Advanced Computing Research]

DSpace
  • Organize and use content today
  • Archive for the future
  • Of course…
    • Images, documents, music
  • But more…
    • Data sets, software, videos, compound items
  • And preserve access and authenticity


5
What is DSpace?
  • Repository with archive emphasis
  • Metadata workflow manager
  • Archive with granular access rights
  • Preservation architecture

Open source
  • Flexible, modifiable
  • Costs: lower?  Maybe, but certainly different
  • Technical details
    • Java application, Linux, Apache, Tomcat, relational database
  • Built on a community of innovation

Loosely coupled architecture
  • Best-of-breed architecture
  • Modular
  • Interoperable, designed for integration
    • e.g., authentication via LDAP, CAS, AD
    • Group definitions
  • Fit easily into campus IT framework
  • Based on open standards
15
Open standards
  • J2EE – Java program code
    • Mac/Windows/Unix agnostic
  • Metadata schema
    • Dublin core, METS
  • SQL
    • MySQL, PostgreSQL, Oracle
  • File formats
    • Tiff, PDF, XML, MP3
    • Global Digital Format Registry
  • Permanent URI
    • Handle. net – name service from CNRI
16
Hierarchy well-suited to consortia
  • Communities
  • Sub-communities
  • Collections
  • Items
  • Bitstreams and bundles

Metadata workflow roles
  • Submitter
  • Reviewer
  • Coordinator
  • Metadata Editor


  • E-mail goes to each person at the appropriate step in the workflow
  • Authorizations are set up in advance for each role in the workflow
22
Submitter permissions
  • Can edit metadata for own submission
  • Can upload files for own submission
  • Cannot do anything once item is submitted
23
Reviewer and coordinator permissions
  • Can review content of all files submitted to collection
  • Can accept or reject all submissions to collection
  • Can send a message explaining decision
  • Rejection stops submission
  • Acceptance lets submission go to next step (cannot edit metadata or change files)
24
Metadata editor permissions
  • Can edit metadata of all submissions to collection
  • Submission automatically becomes part of DSpace after this step (any approval would have happened before)
25
Flexible searching
  • Within a community or collection
  • Across all communities and collections in one DSpace instance
  • Federated searching across DSpace instances through OAI harvesting

Other features
  • News and announcements
  • Notifications about collections
  • Version tracking
30
Challenges
  • Tuning the interface
  • Costs of metadata creation
  • Additional metadata schema
  • Small colleges
    • Are we consumers or developers or both?
  • Support – there are commercial offerings
31
 
32
A pilot program
  • Student theses, journals, monographs, digital collections (e.g., texts, images, multimedia)
  • Open for submission by faculty-sponsored individuals on campus
  • Metadata review
33
 
34
Pilot management
  • Representative management board
  • Faculty sponsorship for collections
  • Service level agreement
35
Service Level Agreement
  • The university
    • provides routine web resources including server, space, backup, limited administrative support without any guarantees for performance or access
    • will maintain long-term access to content (stable URLs, archived copies, pointers to removed materials)
    • does not limit or charge for access to the content, and will not claim copyrights on the content
    • will from time to time promote the Denison University Digital Archive
36
Service Level Agreement
  • The sponsor and contributor
    • are responsible for all content
    • must comply with the current Acceptable Use Policy
    • are fully and individually responsible for compliance with copyright laws and regulations
    • are responsible for page markup, uploading data, maintenance, updates, error corrections, optimization of graphics and multimedia elements, proper titling and initial metadata tagging
    • cannot charge for access
    • will apply for ISSN and will register online publication with abstracting and indexing services, if desired
    • retain full rights over the content, including the right to remove their archived content
37
Strategic role of DSpace
  • Scholarly Communication – Yes!
