This presentation describes the development and implementation of WSU Research Exchange, a permanent digital repository system that is being, adding WSU researchers to the growing list of authors who can self- archive their research publications in support of current worldwide Open Access initiatives. Research Exchange supports a number of services, including harvesting of information by discipline-specific repositories in order to raise the visibility and citation of self-archived research; a permanent naming convention known as handles to minimize broken link problems; and, support for the preservation of included research materials. Additionally, the presentation provides information on new means of dissemination of research and the increasing importance of scholarly communication issues in light of the global development of systems like Research Exchange and of metadata harvesting protocols. Washington State University will be using the DSpace repository software, which was developed by the Hewlett-Packard Labs and the Massachusetts Institute of Technology Libraries. The DSpace application provides access to and preserves digital assets, including digitally-born and digitized materials, pre-prints, post-prints, multimedia materials, WSU records, and publications. In December of 2005, the WSU Libraries convened an Institutional Repository Task Force to develop the WSU Research Exchange and promote this service to WSU researchers. This summer, Task Force members will be identifying early adopters to contribute their research output to this repository. The test WSU Research Exchange system. The production system is currently being built on an Hewlett-Packard server purchased using funds provided by the Provost’s Office and housed in Information Technology’s Departmental Server facility. A summary record in the WSU Research Exchange system. The identifier assigned to the record is durable handle, thus helping to resolve the broken link problem for digital research materials. An important goal of the Research Exchange system is to enhance the visibility of Washington State University’s faculty researchers. The system is architected to support harvesting by discipline-specific repositories, using the Open Archives Initiative-Protocol for Metadata Harvesting (OAI-PMH). Digital items within the Research Exchange become much more visible to the research community because of the OAI-PMH specifications used by the software. Listed below are examples of some discipline specific repository systems that will be able to use harvesting techniques to include Research Exchange item information. The result: the ability for faculty research information to be seamlessly added to and updated in repository systems. MIT’s DSpace deployment illustrates the community, sub-community, and collection structure supported by the DSpace software. The DSpace software supports a decentralized management system, in which authorized users and workflow characteristics can be customized for each collection. The DSpace software is architected to support long-term preservation. WSU’s Research Exchange uses a bitstream format registry table that maps file formats to declared levels of support. Storing, Preserving and Providing Access to WSU Research Through Bitstreams The DSpace system saves files in bitstream (digital) format that can be used for mapping between a particular bitstream format and a declared level of support based on the level of commitment to digital preservation. In all cases, bitstream preservation is the minimum level of support that is provided. The three basic support levels are:  supported: This level is most commonly used for proprietary formats. Based upon the open nature of the format, the submitted bitstream will be reasonably preserved into the future using functional preservation techniques.  known: This level is most commonly used for proprietary formats. While the format is known there is limited information on the file format functions so that committing to providing functional preservation of the format is not possible.  not known: Commitment to preservation of this format is limited to bitstream preservation only. The DSpace software has these basic functionalities:  Metadata: Use of Qualified Dublin Core metadata, a relatively simple description system, with only three required fields (title, language, and submission date).  User interface: A web-based user interface is provided for end-user search and retrieval, submitting documents, and collection administration.  Workflow: Supports different workflows depending on the needs of a faculty member, academic department, or research center. Two example workflows include: direct submission by an approved list of submitters, with items immediately viewable to the public; submission by a list of submitters, with a smaller group of reviewers able to approve the item or storage and public access. Community Sub-Community This could be a specific researcher, a sub-unit of the department or a particular type of publication. Collections Test Communities set up for Research Exchange DSpace software will be customized to meet WSU research needs ABSTRACT Building a Digital Repository WSU-Style This presentation describes the development and implementation of WSU Research Exchange, a permanent digital repository system that will be customized to support the archiving needs of faculty and students at Washington State University. Repositories such as the (WSU) Research Exchange are being developed and implemented at major universities around the world. The (WSU) Research Exchange enables WSU researchers to join the growing list of authors who self-archive their research publications in support of current worldwide Open Access initiatives. Research Exchange raises the visibility and citation of self-archived research while supporting a number of initiatives, including: harvesting of information by discipline-specific repositories a permanent naming convention known as handles that minimizes broken link problems; and, support for the preservation of included research materials. Additionally, the presentation will provide information on new means of dissemination of research and the increasing importance of scholarly communication issues in light of the global development of systems like Research Exchange and of metadata harvesting protocols. WSU Research Exchange is our implementation of MIT’s DSpace, open-source software that was built on the model shown below. The DSpace information model (Source: “DSpace: An Open Source Dynamic Digital Repository”, D-Lib Magazine, January 2003). The Handle for each item is a short numerical permanent identifier that is based on the institution and a sequential item number. The Research Exchange record includes size and format of the file File format and level of support are linked by the DSpace software. Benefits of Depositing Research Materials in the WSU Research Exchange The technology behind WSU Research Exchange  Server operating system: Red Hat Enterprise Linux AS  Database: PostgreSQL Relational Database Management System  Support web delivery of Java DSpace application: Jakarta Tomcat servlet engine  To provide durable identifiers: CNRI Handle System Server  To provide secure communications: Java Secure Socket Extension (JSSE), Verisign SSL certificates Following its implementation at MIT, an international group of institutions using DSpace has evolved, with 137 sites currently registered as production DSpace instances. The widespread use and customization of DSpace has led to the creation of a number of significant grassroots enhancements by DSpace institutions: Use statistics module - University of Edinburgh Creative Commons distribution license support – Creative Commons LDAP [Lightweight Directory Access Protocol] authentication – Brigham Young University
