Digital Object Prototypes Framework Released

Kostas Saidis has released the Digital Object Prototypes Framework. It is available from the DOPs download page.

Here is an excerpt from the fedora-commons-users announcement:

At a glance, DOPs is a framework for the effective management and manipulation of diverse and heterogeneous digital material, providing repository-independent, type-consistent abstractions of stored digital objects. In DOPs, individual objects are treated as instances of their prototype and, hence, conform to its specifications automatically, regardless of the underlying storage format used to store and encode the objects.

The framework also provides inherent support for collections /sub-collections hierarchies and compound objects, while it allows DL-pertinent services to compose type-specific object behavior effectively. A DO Storage module is also available, which allows one to use the framework atop Fedora (thoroughly tested with Fedora version 2.0).

PRESERV Project Report on Digital Preservation in Institutional Repositories

The JISC PRESERV (Preservation Eprint Services) project has issued a report titled Laying the Foundations for Repository Preservation Services: Final Report from the PRESERV Project.

Here’s an excerpt from the Executive Summary:

The PRESERV project (2005-2007) investigated long-term preservation for institutional repositories (IRs), by identifying preservation services in conjunction with specialists, such as national libraries and archives, and building support for services into popular repository software, in this case EPrints. . . .

PRESERV was able to work with The National Archives, which has produced PRONOMDROID, the pre-eminent tool for file format identification. Instead of linking PRONOM to individual repositories, we linked it to the widely used Registry of Open Access Repositories (ROAR), through an OAI harvesting service. As a result format profiles can be found for over 200 repositories listed in ROAR, what we call the PRONOM-ROAR service. . . .

The lubricant to ease the movement of data between the components of the services model is metadata, notably preservation metadata, which informs, describes and records a range of activities concerned with preserving specific digital objects. PRESERV identified a rich set of preservation metadata, based on the current standard in this area, PREMIS, and where this metadata could be generated in our model. . . .

The most important changes to EPrints software as a result of the project were the addition of a history module to record changes to an object and actions performed on an object, and application programs to package and disseminate data for delivery to an external service using either the Metadata Encoding and Transmission Standard (METS) or the MPEG-21 Part 2: Digital Item Declaration Language (DIDL). One change to the EPrints deposit interface is the option for authors to select a licence indicating rights for allowable use by service providers or users, and others. . . .

PRESERV has identified a powerful and flexible framework in which a wide range of preservation services from many providers can potentially be intermediated to many repositories by other types of repository services. It is proposed to develop and test this framework in the next phase of the project.

Trustworthy Repositories Audit & Certification: Criteria and Checklist Published

The Center for Research Libraries and RLG Programs have published the Trustworthy Repositories Audit & Certification: Criteria and Checklist.

Here’s an excerpt from the press release:

In 2003, RLG and the US National Archives and Records Administration created a joint task force to address digital repository certification. The goal of the RLG-NARA Task Force on Digital Repository Certification was to develop criteria to identify digital repositories capable of reliably storing, migrating, and providing access to digital collections. With partial funding from the NARA Electronic Records Archives Program, the international task force produced a set of certification criteria applicable to a range of digital repositories and archives, from academic institutional preservation repositories to large data archives and from national libraries to third-party digital archiving services. . . . .

In 2005, the Andrew W. Mellon Foundation awarded funding to the Center for Research Libraries to further establish the documentation requirements, delineate a process for certification, and establish appropriate methodologies for determining the soundness and sustainability of digital repositories. Under this effort, Robin Dale (RLG Programs) and Bernard F. Reilly (President, Center for Research Libraries) created an audit methodology based largely on the checklist, tested it on several major digital repositories, including the E-Depot at the Koninklijke Bibliotheek in the Netherlands, the Inter-University Consortium for Political and Social Research, and Portico.

Findings and methodologies were shared with those of related working groups in Europe who applied the draft checklist in their own domains: the Digital Curation Center (U.K.), DigitalPreservationEurope (Continental Europe) and NESTOR (Germany). The report incorporates the sum of knowledge and experience, new ideas, techniques, and tools that resulted from cross-fertilization between the U.S. and European efforts. It also includes a discussion of audit and certification criteria and how they can be considered from an organizational perspective.

UK EThOSnet ETD Project Funded

A UK-wide ETD project called EThOSnet has been funded for a two-year period by JISC and CURL (Consortium of Research Libraries). When the project concludes, the British Library will establish the EThOS service based on the work done by EThOSnet.

An excerpt from the press release is below:

The project builds on earlier exploratory work, also funded by JISC and CURL, which between 2004 and 2006 developed a prototype for the service. Independent evaluation has since given the prototype strong backing and suggested further developments, while a recent consultation resulted in expressions of interest from over 70 HE institutions to participate in the emerging e-theses service.

EThOSnet builds on these firm foundations and through collaboration with the British Library and the HE community will transform access to theses in the UK by providing the full text of theses through a single point of entry. In addition, in tandem with the emerging network of institutional repositories in the UK, it promises to become a central element of the national infrastructure for research.

Fez 1.3 Released

Christiaan Kortekaas has announced on the fedora-commons-users list that Fez 1.3 is now available from SourceForge.

Here’s a summary of key changes from his message:

  • Primary XSDs for objects based on MODS instead of DC (can still handle your existing DC objects though)
  • Download statistics using apache logs and GeoIP
  • Object history logging (premis events)
  • Shibboleth support
  • Fulltext indexing (pdf only)
  • Import and Export of workflows and XSDs
  • Sanity checking to help make sure required external dependencies are working
  • OAI provider that respects FezACML authorisation rules

For further information on Fez, see the prior post "Fez+Fedora Repository Software Gains Traction in US."

Fez+Fedora Repository Software Gains Traction in US

The February 2007 issue of Sustaining Repositories reports that more US institutions are using or investigating a combination of Fez and Fedora (see the below quote):

Fez programmers at the University of Queensland (UQ) have been gratified by a surge in international interest in the Fez software. Emory University Libraries are building a Fez repository for electronic theses. Indiana University Libraries are also testing Fez+Fedora to see whether to replace their existing DSpace installation. The Colorado Alliance of Research Libraries (http://www.coalliance.org/) is using Fez+Fedora for their Alliance Digital Repository. Also in the US, the National Science Digital Library is using Fez+Fedora for their Materials Science Digital Library (http://matdl.org/repository/index.php).

Open Access Repository Software Use By Country

Based on data from the OpenDOAR Charts service, here is snapshot of the open access repository software that is in use in the top five countries that offer such repositories.

The countries are abbreviated in the table header column as follows: US = United States, DK = Germany, UK = United Kingdom, AU = Australia, and NL = Netherlands. The number in parentheses is the reported number of repositories in that country.

Read the country percentages downward in each column (they do not total to 100% across the rows).

Excluding "unknown" or "other" systems, the highest in-country percentage is shown in boldface.
