Presentation structure

Background: DSpace 1

Successes and key strengths

Why develop DSpace2?

Current status of DSpace 2 development

The future for DSpace 2

DSpace1: The world has turned

Written for MIT library

Used by >100 institutions

Written as a Digital Preservation Testbed

Used in institutional repositories, open access systems, e-science data, learning objects etc etc

Written by closed development team

Developed by an extended global community

DSpace1: Key strengths

Enables self-archiving

Simple, easy-to-use interface

Browse indices

Guided ingest process

Starting platform for digital preservation

Bitstream preservation

Persistent identifiers (Handles)

Use for open access publishing

Community gaining momentum

Why develop DSpace2?

DSpace2.....

Address DSpace 1 weaknesses

Take new opportunities

DSpace 1: Weaknesses

Limited I18N capability

Customization can be difficult

JSP override mechanism + customizable submission forms (in v1.2.2b1)

Difficult to maintain customizations

No extension mechanism

Limited Metadata handling

“Missing” features

Version control

Sane HTML storage

DSpace 2 Opportunities: 1

Build in internationalization from the ground up

Enable use of novel storage systems?

Storage Resource Broker (http://www.sdsc.edu/srb)

LOCKSS (Lots Of Copies Keeps Stuff Safe)

http://lockss.stanford.edu/

Modular Architecture

Easier to customize

Easier to extend

Tailor DSpace for different purposes

Better software quality → Faster releases

DSpace 2 Opportunities: 2

Most important 3 features of modern web data services: -

Interoperability

Interoperability

Interoperability

Web Services technology

More novel deployments

Increased architectural support for emerging industry standards

OAIS for data structure and process modeling

Standardised packaging for export and import

SRW for external search?

Better support for OAI

DSpace2 Opportunities: 3

Scalability

File size (>2GB)

# of items

# of TB

# of simultaneous users

Replication / mirroring of DSpace

Improved metadata handling

RDF?

Extensible Dublin Core

Version Control

Current Status of DSpace 2

Design planning work underway

Proposal + discussion
