The Relog Experiment reports that, at a Canadian Association of Research Libraries meeting on institutional repositories at Access 2008, most attending libraries that used DSpace were reluctant to upgrade to 1.5 and were not using Manakin.

Here's an except that explains their reservations:

• customizations made to DSpace 1.4 will take a lot of programming time to move over to 1.5
• certain plug-ins and enhancements that are in heavy use in 1.4 have not yet been made available for 1.5
• administrators are evaluating other platforms and are not willing to invest the time in upgrading to 1.5 if they end up switching platforms
• programmers are hard to find, train and retain

The Repositories Support Project has launched The DSpace Course, which has 20 modules that include workbooks and presentation slides. A Live CD is also available that has a version of DSpace that runs without requiring that it be installed on a server.

The DSpace Foundation has published the July/August NewSpace newsletter.

The DSpace Foundation and Fedora Commons have announced that they will collaborate on future digital repository initiatives.

Here's an excerpt from the press release:

Today two of the largest providers of open source software for managing and providing access to digital content, the DSpace Foundation and Fedora Commons, announced plans to combine strengths to work on joint initiatives that will more closely align their organizations' goals and better serve both open source repository communities in the coming months. . . .

The collaboration is expected to benefit over 500 organizations from around the world who are currently using either DSpace (examples include MIT, Rice University, Texas Digital Library and University of Toronto) or Fedora (examples include the National Library of France, New York Public Library, Encyclopedia of Chicago and eSciDoc) open source software to create repositories for a wide variety of purposes. . . .

The decision to collaborate came out of meetings held this spring where members of DSpace and Fedora Commons communities discussed multiple dimensions of cooperation and collaboration between the two organizations. Ideas included leveraging the power and reach of open source knowledge communities by using the same services and standards in the future. The organizations will also explore opportunities to provide new capabilities for accessing and preserving digital content, developing common web services, and enabling interoperability across repositories.

In the spirit of advancing open source software, Fedora Commons and DSpace will look at ways to leverage and incubate ideas, community and culture to:

1. Provide the best technology and services to open source repository framework communities.
2. Evaluate and synchronize, where possible, both organizations' technology roadmaps to enable convergence and interoperability of key architectural components.
3. Demonstrate how the DSpace and Fedora open source repository frameworks offer a unique value proposition compared to proprietary solutions.

The announcement came on the heels of an event sponsored by the Joint Information Systems Committee's (JISC) Common Repository Interface Group (CRIG) held at the Library of Congress. The event, known as "RepoCamp," was a forum where developers gathered to discuss innovative approaches to improving interoperability and web-orientation for digital repositories. Sandy Payette, Executive Director of Fedora Commons, and Michele Kimpton, Executive Director of the DSpace Foundation, reiterated their commitment to collaboration and encouraged input and participation from both communities as work gets underway.

A paper by researchers from the National Library of Medicine ("Testing the Scalability of a DSpace-based Archive") finds that DSpace can support an archive with a million items. The tested system "is built upon MIT's DSpace software (Version 1.4), with some modifications and enhancements to better facilitate batch based processing."

Here's an excerpt from the conclusion:

We conclude that the version of DSpace used in SPER (with MySQL database) shows acceptable ingest performance for a million-item archive. . . .

The experimental results shown here pertain to items with mostly one or two monochrome TIFF images, though a few items have up to 100 images. However, a number of inferences may be derived from these results.

• No real problems were found in ingesting a million items to the archive, using a Sun X4500 server machine, in terms of either performance or reliability of the SPER/DSpace software architecture and implementation. . . .
• With the increase in archive size, the average ingest time of an item increases in a smooth and predictable way.
• With increasing number of TIFF images, the ingest time (per item) increases by three to four percent for each additional image.
• If color TIFF images were used, the ingest times would increase slightly due to the overhead of copying additional data to the upload area, and to the archive's asset storage. However, other archival overheads should not change.

An interview with Brad McLean, DSpace Foundation's New Technology Director, has been published in the latest issue of NewSpace.

The Foresite Project has released the foresite-toolkit.

Here's an excerpt from the announcement (footnotes removed):

The Foresite project is pleased to announce the initial code of two software libraries for constructing, parsing, manipulating and serialising OAI-ORE Resource Maps. These libraries are being written in Java and Python, and can be used generically to provide advanced functionality to OAI-ORE aware applications, and are compliant with the latest release (0.9) of the specification. The software is open source, released under a BSD licence, and is available from a Google Code repository . . . .

Foresite is a JISC funded project which aims to produce a demonstrator and test of the OAI-ORE standard by creating Resource Maps of journals and their contents held in JSTOR, and delivering them as ATOM documents via the SWORD interface to DSpace. DSpace will ingest these resource maps, and convert them into repository items which reference content which continues to reside in JSTOR. The Python library is being used to generate the resource maps from JSTOR and the Java library is being used to provide all the ingest, transformation and dissemination support required in DSpace.
