Fedora GSearch 2.0 Release Takes Advantage of Solr

Copenhagen, DKFebruary 29, 2008

The Fedora GSearch team is pleased to announce the release of GSearch 2.0 for Fedora. The new release is designed to support Fedora 2.2.1. GSearch 3.0 for Fedora version 3.0, with message-based communication is currently being developed by Eddie Shin, Fedora Commons. The Fedora Generic Search Service or "GSearch" is part of the Fedora Service Framework that presents users with a service-oriented architecture approach that allows new services to be built as stand-alone web applications that run independently of the Fedora repository.

Peter Murray, OhioLink, observed in a Dec. 31, 2006, post to his blog The Disruptive Library Technology Jester, "GSearch - where "G" stands for "General" but could equally well stand for "Gert" Schmeltz Pedersen, its lead developer from the Technical University of Denmark." Gert and colleagues Beth Kirschner, Binaya Poudyal, Blake Anderson, Boon Low, Christian Tonsberg, Eric Brown, Jun Yamog, Junran Lei, Luis Zorita, Matt Zumwalt, Matthias Razum, Michael Appleby, Michael Hoppe, Nikolai Schwertner, Patrick Monbaron, Pierre-Yves Landron, Ranju Upadhyaya, Robert Sherratt, Ryan E. Scherle, Sam Liberman, Shunde Zhang, Steve DiDomenico Thierry Michel, and Xinjian Guo regularly contribute their work on GSearch to the Fedora Commons community as well as to DEFF, Denmark's Electronic Research Library, which funded the Fedora GSearch project.

Fedora GSearch 2.0 is a feature release compatible with Fedora 2.2.1 with improved configurability including seven new features requested by users designed to exploit more features of Solr. The Fedora System Documentation at http://www.fedora-commons.org/developers links to FedoraGSearch information that includes an introduction, list of new features, installation instructions, configuration, and additional architectural information.

The same information is available in the source download from sourceforge.net at src/html/search-service.html, and after installation at http://localhost:8080/fedoragsearch/index.html.

New Fedora Gsearch 2.0 features include:

  • Added a plugin for the Apache Solr search server.
  • Added a sortFields parameter to gfindObjects for Lucene; sorting search results as specified; exploiting Lucene classes for sorting.
  • Added optimize options for Lucene indexing; the mergeFactor and maxBufferedDocs; properties will affect performance as explained in the Lucene documentation; The optimize action of the updateIndex operation will perform the Lucene method; call IndexWriter.optimize(), which merges all segments together into a single segment; optimizing an index for search. The optimize() is no longer called after each updateIndex.
  • Added parameters to the indexDocXslt parameter of the updateIndex operation, enabling the transfer of param values into the indexing stylesheet.
  • Added untokenizedFields property to Lucene index.properties files. Adding the property with a list of all untokenized fields will ensure that they all select the appropriate analyzer.
  • Added properties snippetBegin and snippetEnd, making highlight code configurable.
  • Added property for custom URIResolver used by xslt transformers for basic authorization and SSL, see the example dk.defxws.fedoragsearch.server.URIResolverImpl class.
  • Removed encoding of special characters in indexFields. Snippets now show special characters without modification. Indexes should be reindexed.

For examples, see the index.properties file in configTestOnLucene/index/TestOnLucene. To download, see http://downloads.sourceforge.net/fedora-commons/genericsearch-2.0.zip.

Muradora 1.2.1 Now Available

Sydney, AUFebruary 18, 2008

The DRAMA team has announced the 1.2.1 release of Muradora which is now available for download at http://www.muradora.org/software. More information about Muradora (including deployment guides) can be found at http://www.muradora.org. DRAMA (Digital Repository Authorization Middleware Architecture) is a sub-project within RAMP that aims to develop a web front-end for Fedora repositories, and to re-factor Fedora authentication and authorization into pluggable middleware components. Please share your ideas and feedback with the developers.

Muradora is an easy to use repository application that supports federated identity (via Shibboleth authentication) and flexible authorization (using XACML). Muradora leverages Fedora's modularity, flexibility and scalability to form the core back-end repository, while different front-end applications (such as portlets or standalone web interfaces) can all talk to the same instance of Fedora, and yet maintain a consistent approach to access control.

Muradora and its related components are released under the Apache 2 license.

A major emphasis of Muradora 1.2.1 release was to fix bugs and to make several new features available:

  • Better support for new XForms scripts for different metadata standards
  • Preliminary support of Open Journal System (OJS) dissemination styles
  • Support for IMS learning objects
  • Automatic thumbnail generation for images
  • New administration panel for administrators to assign access control to the repository
  • Statistical view of accesses to resources

A running demo of Muradora can be found at http://demo.muradora.org. The DRAMA team has also made a Live DVD containing the complete installation of Muradora and its related components available. The Live DVD may be run directly from it without having to install Muradora on a hard disk. This DVD will be available for download within the next few days from the same address as above.

Data Archiving and Networked Services "DANS" to Plan Dutch Users Group Meeting

Amsterdam, NLFebruary 15, 2008

The Netherlands Organization for Scientific Research coordinates scientific research in the Netherlands. Dutch science claims 2.6 percent of the global output of scientific publications where annual scientific research expenditures amount to approximately 9 billion euro.

The Royal Netherlands Academy of Arts and Sciences is a forum, conscience, and voice for the arts and sciences in the Netherlands. The Academy promotes the quality of scientific and scholarly work and strives to ensure that Dutch scholars and scientists make the best possible contribution to the cultural, social, and economic development of Dutch society.

"DANS" is the Dutch national organization responsible for storing and providing permanent access to research data from both sources, humanities and social sciences. DANS is developing the Easy On Fedora (EOF) prototype using Fedora software. The aim of the EOF project is to establish an improved and easily expandable software infrastructure as the basis for many solutions.

DANS is currently gauging community interest in planning and participating in a Fedora Netherlands User Group Meeting to discuss how Fedora is being used there. Attendees will be encouraged to share their own experiences, and to learn from each other's Fedora efforts.

Easy On Fedora will be among the topics to be presented. The EOF prototype provides users with software as well as with the required infrastructure, in addition to a completely updated EASY web application that uses the infrastructure. Using standard solutions like Fedora to facilitate interoperability, EOF creates more structure at the data level with content models. The project aims to be future-oriented and "future-proof" as much as possible. EOF has done extensive research on the future of archiving in many fields and are anxious to share information with the Fedora community. If you are interested in participating please contact Lodewijk Bogaards. Date and location information will follow.

Fedora-powered "University Converged Newsroom"

Ithaca, NYFebruary 1, 2008

Florencio Almirol has an interest in how university news is managed and propagated. Almirol, a graduate student at California State University Los Angeles, heads up a student team that is prototyping the CoolStateLA Enterprise System. The project is led by Professor Jon Beaupre, Professor of Broadcast Journalism in the department of Communication Studies, and Professor Russ Abbott, computer science technical advisor. CoolStateLA is aimed at creating a "converged newsroom" that combines the ability to create, manage, review, and store content that will be simultaneously available to university media outlets - a newspaper; a web site; a blog facility; RSS news feed filter; text feeds to create email alerts; news webcasts; and Internet radio. CoolStateLA is a one-stop shop for getting the word out on campus and beyond. Almirol says, "Fedora's content model architecture coupled with versioning capabilities made it ideal for pulling in and pushing out different types of media."

The system combines a workflow application specifically purposed for communications activities in a typical university news bureau that includes roles for a programmer, news director, senior editor, assignment editor, reporter/producer, and correspondent. Joomla, an open source content management system, was chosen because it is used by newspapers and has a customizable framework. Fedora is the asset manager component and serves as the integration point for all content flowing in and out of the system.

CoolStateLA team members are Farrukh Shakil - Fedora integration; Dhaval Joshi - Joomla; Mark Luntzel - RSS Feed Filter; Manoj Katwal - User Interface, and; Sepideh Nazari - Workflow. For more information contact Florencio Almirol.

Discuss Repository Issues With A Community Of Repository Managers And Builders

Philadelphia, PAJanuary 23, 2008

One of the issues raised during the National Institute of Standards (NISO) Forum "Getting the Most out of Your Repository" last month in Beltsville, Maryland, was the need for communications among those who are maintaining and building institutional repositories. The clear need to build a sense of community among repository managers was a topic on the minds of attendees in presentations and during breaks. An active email distribution list for sharing problems, concerns, and ideas has been created to help build this sense of community, and allow participants to more effectively address their repository practices and development.

A new open forum REPOMAN-L (Institutional Repository Managers' Mailing List) is offered for the discussion of issues and ideas that confront repository managers. The organizers hope that individuals will subscribe and participate enthusiastically, and use this list for problem-solving and sharing advice, for example:

  • poll the group on practices at their institutions
  • ask about any aspect of development from policy to outreach initiatives to software evaluation
  • share links to useful tools and references
  • explore rationale around decisions list members are making about their repository.

The REPOMAN-L mailing list is focused on finding out how individuals are confronting the challenges associated with each institution's repository on a day-to-day basis and solutions that have been found. The success of this new forum will hinge on sharing ideas and concerns, to consider them with open minds, and to offer colleagues the best advice possible.

REPOMAN-L is for problem-solving and community-building: it is the hope of the list creators that individuals will participate and continue to encourage and support the open exchange of ideas.

How To Subscribe:
To subscribe to REPOMAN-L, go to https://listserv.indiana.edu/cgi-bin/wa-iub.exe?A0=REPOMAN-L, click "Join or Leave REPOMAN-L," and fill in the fields. You will be sent an email to confirm your subscription. (For those who are already familiar with LISTSERV lists, you may also subscribe by sending the command "subscribe repoman-l" in an email message to listserv@listserv.indiana.edu.) Once you have subscribed, you can send questions and comments to repoman-l@listserv.indiana.edu for distribution to the list subscribers.

REPOMAN-L is hosted by Indiana University, but is not affiliated with the University. Contact Richard Griscom (griscom@upenn.edu), University of Pennsylvania, or Leah Vanderjagt (lvanderj@library.ualberta.ca), University of Alberta, with questions.

Now Available: Beta One Release of Content Model-driven Fedora 3.0

Ithaca, NYDecember 21, 2007

The 12th release of the popular Fedora software is now available for testing. The first beta version of Fedora 3.0 featuring a Content Model Architecture (CMA), an integrated structure for persisting and delivering the essential characteristics of digital objects in Fedora, is available at http://www.fedora-commons.org/. The Fedora CMA plays a central role in the Fedora architecture, in many ways forming the over-arching conceptual framework for future development of Fedora Repositories.

Like a well-thumbed book on a shelf, digital content is stored with the expectation that intellectual works will be the same each time they are accessed, whether the content was put away yesterday, or many years ago. Fedora is a simple, flexible and evolvable approach to delivering and sharing the "essential characteristics" of enduring digital content. Librarians, archivists, records managers, media producers, authors and publishers use patterns of expression formats such as books, journals, articles, collections to convey the essential characteristics of content. The capabilities of digital tools combined with essential characteristics of digital works result in well-understood patterns of expression for different types of content models.

The software engineering community also utilizes patterns of expression for the development of complex computer systems. The same concepts that satisfy agile IT infrastructures can help provide solutions for creating, accessing and preserving content. The Fedora CMA builds on the Fedora architecture-downloaded more than 18,000 times in the last 12 months-to simplify use while unlocking potential.

Dan Davis, Chief Software Architect, Fedora Commons, explains the CMA in the context of Fedora 3.0, "It's a hybrid. The Fedora CMA handles content models that are used by publishers and others, and is also a computer model that describes an information representation and processing architecture." By combining these viewpoints, Fedora CMA has the potential to provide a way to build an interoperable repository for integrated information access within organizations and to provide durable access to our intellectual works.

We encourage the Fedora community to download and experiment with Fedora 3.0 Beta 1. It is particularly important to receive comments while the software is still being developed to help ensure this important update to the Fedora architecture meets the needs of the community. Please contribute your observations and comments to fedora-commons-developers@lists.sourceforge.net or fedora-commons-users@lists.sourceforge.net. Fedora 2.2.1 will remain available for all production repository instances.

API-M-LITE
A simple web interface for managing and modifying objects is an item on many Fedora Users' wish lists. For the release of Fedora 3.0 Beta 1 developer Matt Zumwalt, MediaShelf, decided to take the lead by creating API-M LITE. Zumwalt says, "The idea of Restful interfaces has gotten a lot of traction lately, especially in the Ruby world. It seemed like a good fit for Fedora, so MediaShelf decided to make it happen. I have been using the API since August and am certain that it will enable all of us to start using Fedora in radical new ways. We are very happy to contribute this code to Fedora Commons and look forward to making further contributions in the future."

Acknowledgements
The release of Fedora 3.0 is made possible by a collaborative partnership with community developers and the Fedora core software development team that include: Chris Wilper (Fedora Commons), Eddie Shin (Fedora Commons), Robert Haschart (Fedora Commons),, Ross Wayland (Fedora Commons),Matt Zumwalt (API-M LITE, Media Shelf), Cuong Tran (API-M LITE, Digital Innovation South Africa), and many others.

Preservation and Archiving Focus of Sun Meeting in Paris

Ithaca, NYNovember 30, 2007

The Sun Microsystems™ Preservation and Archiving Special Interest Group (Sun PASIG), a group dedicated to working on the unique problems of storage and data management, workflow, and architecture for very large digital repositories, held its second meeting in Paris for 171 industry, education, government, and library services representatives from Europe, the United States, Australia and New Zealand on November 14-16, 2007. Sun PASIG plans to host a meeting of leaders concerned with issues of maintaining or restoring access to artifacts, documents and records semi-annually.

Day one was devoted to Sun technology workshops. The opening session reviewed the current state of asset management systems. The focus of presentations was in the commercial realm rather than on academic or library applications. The panel was made up of consultants and software integrators who had worked with Sun. Presentations from two Sun technologists on aspects of preservation and archiving followed. The day ended with a Sun Honeycomb Users' Group meeting. Representatives from eight different institutions that are using the StorageTek™ 5800 system, also known as "Sun Honeycomb," talked about their experiences. Most had recently received system hardware so had only just begun to work with the system; more than half of the presenters were using the Fedora software platform.

During the rest of the meeting presentations and updates were given on the status of Fedora Commons, DSpace and Eprints by a mix of academic and national library project professionals. The majority of projects and initiatives were using Fedora. National libraries were well represented, both on the program and among the participants. The majority of representatives expressed a preference for open-source software, and for the Fedora platform, in particular. A notable exception was the National Library of New Zealand, that is working with Ex Libris to develop a proprietary system. Working groups met to discuss topics that included Use Cases and Business Models, Architecture, Security and others.

Fedora Commons held an after-hours session to discuss ways to work with companies who provide software integration services and software products built around Fedora software. Companies represented included ATOS Origin, CARE Affiliates, FIZ Karlsruhe and VTLS, as well as representatives from Sun Microsystems. Several other interested people from the conference also attended.

Meeting presentations, agenda, and a list of attendees are available here. Questions about Sun PASIG activities may be sent to Art Pasquinelli, Education Market Strategist Sun Global Education and Research at art.pasquinelli@sun.com.

Fedora UK and Ireland Users Host 18 Institutions at London Meeting

London, UKNovember 27, 2007

Fedora users excel at finding opportunities to talk about making better use of Fedora software's unique capabilities. On November 22, 2007, 32 representatives from Fedora projects gathered at Birkbeck College in London for the most recent Fedora UK and Ireland User Group Meeting to do just that. The morning session featured reports from members followed by presentations of general interest in the afternoon. Chris Awre's (University of Hull) meeting notes and selected presentations are available online. Highlights from community presentations follow.

2007 marks the centenary anniversary of the National Library of Wales (NLW). What began as an experimental Fedora project at NLW over three years ago has become an ongoing program at this national library dedicated to preserving Welsh culture, heritage and knowledge for the people of Wales. Paul Bevan explained that NLW uses Fedora with VITAL. Challenges include ingest scalability of large collections that may include 1,000,000 images. NLW continues to look at ways to streamline overall processes to get more content "in," especially now that other teams at NLW have discovered what the repository can do for them.

Rightscom specialises in the provision of solutions for the management, trading and protection of intellectual property rights and digital content in the network environment. Martin Dow presented Fedora "as a storage layer in the overall technology stack" in a suite of ongoing projects: TIME (Testbed for Interoperability of Metadata for E-Books); RELI (Registry of Electornic Licences), and; RIDIR (Resourcing IDentifier Interoperability for Repositories). Collaborating with the University of Hull, they have identified the importance of semantics for the RIDIR project as clear descriptions of what is being described is essential. RDF functionality within Fedora is proving invaluable to this work.

David Flanders, Bloomsbury Colleges, presented an early look at a project that aims to "Enable anyone to easily install a repository system for their entire institution's use in one day; therefore allowing institutions to focus on the real work of the repository: collecting and enhancing their content!" Fedorazon (Fedora plus Amazon Web Services) will accomplish this by using "Amazon Web Services (AWS) which will enable libraries to forego the cost and maintenance fees of server hardware installations (outsourcing the work to AWS's EC2 and S3). Instead the server configuration for Fedora will be pre-loaded as an "Amazon Machine Image" which enables the immediate "out of the box" installation of Fedora on a highly-scalable and robust network."

The StORe (Source-to-Output Repositories) Project is a collaborative effort among 9 UK and US institutional partners led by the University of Edinburgh that seeks to add value to the intellectual products of academic research by enabling repositories of published reports and papers to interact directly with the repositories of source data. Fedora is used as a gateway for people to upload data into the Archive. They are also keen on investigating Muradora as a way to implement security.

The UK and Ireland Users Group has agreed to help organize the Fedora User Group Meeting to be held in Southhampton on April 3-4, 2008, as part of the Open Repositories Conference. The next UK and Ireland Users meeting will be held in Dublin to coincide with the Seventh International JISC/CNI Conference scheduled for July 2008 in Belfast.

U Maryland Launches Digital Collections Portal Based on Fedora Platform

College Park, MDNovember 30, 2007

The University of Maryland Libraries has announced the launch of its digital collections portal at http://www.lib.umd.edu/digital/.

This release marks two and a half years of work in the creation of a repository that serves the teaching and research mission of the University of Maryland Libraries. Many of the objects are digital versions from Maryland's Special Collections (such as A Treasury of World's Fairs Art and Architecture) or are new virtual collections (The Jim Henson Works). Other collections (such as Films@UM) support the teaching mission of the Libraries. This release also marks the integration of electronically available finding aids, ArchivesUM, into the repository architecture, creating a framework for digital objects to be dynamically discovered from finding aids.

The repository is based on the Fedora platform, uses Lucene for indexing, and Helix for streaming video. The repository features almost 2500 digital objects, with new objects added monthly. Object types currently delivered include full text (both TEI and EAD), video, and images. Objects can be discovered within a collection context or via a search across multiple collections. Cross-collection discovery is achieved through a common metadata scheme and controlled vocabulary. This metadata scheme also provides for individual collections to have more granular domain-specific metadata.

Feedback and comments are welcome at http://www.lib.umd.edu/digital/contact.jsp.

On the New Jersey Digital Highway with Fedora

New Brunswick, NJNovember 26, 2007

With Fedora under the hood, statewide collaborators on the "New Jersey Digital Highway" (http://www.njdigitalhighway.org/) are providing seamless access to historical collections for every user in the state. Funded in part by a National Leadership Grant from the Institute of Museum and Library Services (IMLS), the New Jersey Digital Highway is a three-plus-year project led by Rutgers University that has digitized more than 10,000 pictures, records, and oral histories and is serving as a model for how to connect community cultural organizations through a central Web site.

"This is about local ownership and shared access," says Linda Langschied of Rutgers University Libraries and PI for the NJDH project. "It is a true statewide preservation service. It's books, reports, audio, and video. The services developed for collections owners is a critical component. We don't do the work for the cultural heritage partners. It's their collection - they manage it, they run it. But we assist with consultation and can lend equipment."

What that meant was finding a digital platform that could be used by all statewide institutions to mount their objects and descriptive metadata. They found that platform in FEDORA (Flexible Extensible Digital Object Repository Architecture) that is both customizable and allows local institutions to have true control over what they digitize and make available.

With a promise to digitize some 10,000 objects, Rutgers went forward with 17 partners that include large state institutions like public television station NJN to small and diverse collection holders like Seabrook Educational and Cultural Center and the American Hungarian Foundation. They launched the site showcasing a topic near and dear to New Jersey residents: the state's rich immigrant heritage.

"We are the immigrant state," Langschied says. "For so many people, this was the doorstep to America. New Jersey is among the most diverse states in the nation, with so many wonderful stories to tell. This was a perfect opportunity."

Merging collections from around the state, The Changing Face of New Jersey: the Immigration Experience from Earliest Times to the Present covers four centuries of immigration in the Garden State through eye-catching, fully searchable maps, photos, sheepskin deeds, audio and video histories, immigration records, letters, and diaries. Through the Web site, teachers can find curriculum content standards, desk references on history and ethnic education, and lessons on how to use digitized and primary resources in history education. Students can get help with homework or questions about New Jersey culture and history or get advice and assistance with research papers. And researchers can find links to genealogy resources from the state and individual counties to help uncover family histories.

With 10,000-plus visitors a month, evaluations of the New Jersey Digital Highway have been glowing thus far, according to a final report, with visitors lauding the layout and the integration of different communities.

The accolades don't end at New Jersey's borders. When Virginia Tech suffered tragedy earlier this year with a horrific student shooting, tributes, letters and messages of condolence piled up quickly. By the end, the university had amassed more than 75,000 pieces, but had no plan in place to deal with them. Within the technology community, Rutgers had earned so much renown for its adaptation of FEDORA that Virginia Tech immediately contacted the university's library to help create an online digital memorial and repository. That project continues, with plans to have a Web site up in the near future.

"We want to become the best digital library project that exists," Langschied says. "We want to partner with other organizations, form a close community of FEDORA users and engage in collaborative development with them. At the end of the day, our goal is to provide seamless access to historical collections for every user in the state."

Fedora Commons Integrates Its Software Platform with the Sun StorageTek™ 5800 System

Ithaca, NYNovember 13, 2007

Fedora Commons, a non-profit organization which provides sustainable technologies to create, manage, publish, share and preserve digital information assets, announced today plans to integrate the Fedora Commons software platform with the Sun StorageTek™ 5800 System. This collaboration provides a substantial opportunity to advance open systems for durable access to the digital information assets, which increasingly forms the basis for our intellectual, organizational, scientific and cultural heritage.

The Fedora Commons free, open-source software platform uses a service-oriented architecture that enables the creation of collaborative, integrated information spaces where any information entity can be linked to any other entity. The StorageTek 5800 system has advanced data integrity, resilience and failure tolerance over other storage system designs, and includes customer-defined arbitrary metadata indexing and search. Customers can seamlessly scale, saving millions of dollars in administrative costs over traditional storage, and be assured of an advanced level of data availability.

During the creation or authoring of intellectual works, changes occur rapidly, but over their lifecycle these works become fixed information assets. New scholarship is built upon earlier works and new science is built upon other research. Without durable access to previous works, research progress cannot be sustained. Unless key digital assets such as datasets and analyses are reliably kept and their authenticity is guaranteed, the scientific method may be compromised and the results may be questioned. The StorageTek 5800 provides a powerful capability to handle fixed unstructured information assets.

The Fedora Commons software platform and StorageTek 5800 architecture form a natural synergy for the creation, management, use and care of fixed information. Both systems recognize that, over time, all technologies and formats change. Dan Davis, Fedora Commons Chief Software Architect, notes, "We must develop an open-ended, evolutionary, interoperable architecture, built upon open standards, to ensure that our digital heritage remains accessible and useful, now and in the future."

It is hard to imagine all the ways in which our digital information assets will be used and how knowledge will be synthesized in the future. Users and software applications must be free to use, fuse (mash-up), and repurpose information in new and innovative ways. Dan Davis observed, "The StorageTek 5800 extensive and flexible support for metadata closely integrated with the content is a natural enabler for the Fedora Commons semantic linking and dissemination capabilities. Using our offerings together will provide a straightforward, easy way to support the entire information lifecycle from creation to preservation, and to facilitate rapidly building innovative applications or mash-ups while ensuring your information is secure."

National Science Digital Library (NSDL) Introduces NCore–Fedora-based Virtual Library Tools

Washington, D.C.November 6, 2007

The National Science Digital Library (http://nsdl.org) Core Integration team at Cornell University led by Dean Krafft presented an overview of "NCore," an open source suite of technologies and standards that power the National Science Digital Library's (NSDL) core infrastructure, at NSDL's Annual Meeting held in Washington, D.C., November 6-8, 2007. Download the presentation.

NCore technologies and standards replace NSDL's original metadata records-based data paradigm allowing for greater flexibility in collaborating and creating context around library resources. In the initiative's first phase, completed in January 2007, NSDL Core Integration successfully implemented existing library services on top of NCore—a change that was largely invisible to users. Now, NSDL is leveraging what the Fedora-based NCore platform has to offer by introducing next-generation library services and collaborative tools.

Managing and Maintaining Digital Libraries with NCore

NCore is a general platform for building semantic and virtual digital libraries united by a common data model and interoperable applications. DLESE, the Digital Library for Earth Science Education (http://dlese.org), ported their existing infrastructure to NSDL using NCore. By overlaying their data model on top of the NCore model, developers enabled specialized DLESE services to continue without loss of functionality, and to co-exist alongside of, but independent from, NSDL.

The NCore API (http://sourceforge.net/projects/nsdl-core) was used to build the DLESE index by reading DLESE metadata from the Fedora-based NSDL Data Repository (NDR), using the NDR API (http://sourceforge.net/projects/nsdl-core), and then building the index. The key technical point in this step was to extract the required metadata from NDR objects.

The DLESE Search Service is run from the index and is used to power the DLESE library search and browse functionality. Use of the NSDL Data Repository as the primary metadata repository required no modifications to DLESE Search Service. The indexes and search service remain the same, which means the DLESE library interface and all other interfaces that use the NCore service continue to operate without modification.

Inside NCore

The NCore platform consists of a central repository built on top of Fedora, a data model, an API, and a number of fundamental services such as full-text search or OAI-PMH. Innovative NSDL services and tools that empower users as content creators are now built on, or transitioning to, the NCore platform. These include: the Expert Voices blogging system (http://expertvoices.nsdl.org/); the NSDL Wiki (http://wiki.nsdl.org/index.php/NSDL_Wiki); the NSDL OAI-PMH metadata ingest aggregation system; the OAI-PMH service for distributing public NSDL metadata; the NSDL Collection System (NCS), derived from the DLESE Collection system (DCS); the NSDL Search service; and the OnRamp content management and distribution system (http://onramp.nsdl.org).

Because NCore is a general Fedora-based open source platform useful beyond NSDL, Core Integration developers at Cornell University have made the repository and API code components of NCore available for download at the NCore project on SourceForge (http://sourceforge.net/projects/nsdl-core). Over the next six months, NSDL will release the code for major tools and services that comprise the full NCore suite on SourceForge.

The NCore project aims to support NSDL's continued growth as a semantic and virtual digital library providing open source educational cyberinfrastructure services and tools in support of teaching and learning, while meeting the needs of new, existing, and evolving digital libraries. For more information contact Aaron Birkland (birkland@cs.cornell.edu).

Open Archives Initiative Announces Public Meeting on March 3, 2008 to Release Object Reuse and Exchange Specifications

Ithaca, NY and Los Alamos, NMOctober 31, 2007

On March 3, 2008, the Open Archives Initiative (OAI) will hold a public meeting at Johns Hopkins University in Baltimore, MD, to introduce the Object Reuse and Exchange (ORE) specifications. The ORE specifications are developed in response to a significant challenge that has emerged in eScholarship. In contrast to the paper publications of traditional scholarship, or even their digital counterparts, the artifacts of eScholarship are complex aggregations. These aggregations consist of multiple resources with varying media types, semantics types, network locations, and intra- and inter-relationships. The future of scholarly communication, research, and higher education infrastructure requires standardized approaches to identify, describe, and exchange these new outputs of scholarship.

The ORE specifications address this challenge with the ORE data model that defines how to associate an identifier, a URI, with aggregations of web resources. By referring to these identifiers, aggregations can then be linked to, cited, and described with metadata, in the same manner as any web resource. The ORE data model also makes it possible to describe the structure and semantics of these aggregations. The ORE specifications define how these descriptions can then be packaged in the XML-based Atom syndication format or in RDF/XML, making them available to a variety of applications.

In addition to their utility in eScholarship, the ORE specifications also apply to our everyday web use where we often encounter aggregations such as multi-page HTML documents and collections of multi-format images on sites like flickr. OAI-ORE descriptions of these aggregations can be used to improve search engine behavior, provide input for browser-based navigation tools, and develop automated web services to analyze and preserve this information.

The March 3 meeting at Hopkins is intended for information managers and strategists, and implementers of networked information systems. It will be led by the two coordinators of OAI-ORE, Carl Lagoze of Cornell University and Herbert Van de Sompel of Los Alamos National Laboratory. Attendees will learn about the ORE data model. They will also learn about the translation of this data model to the XML-based ATOM syndication format. In addition, they will hear the results of initial experiments with the specifications by OAI-ORE community members. There will be ample time for discussion and questions and to meet other members of the OAI-ORE community. Detailed information for the meeting is at the registration page at http://www.regonline.com/oai-ore (NOTE: attendees must register in advance and attendance is limited). A subsequent meeting with similar content will be held in the UK in connection with the Open Repositories 2008 Conference. An announcement will be made when details are settled.

About the Open Archives Initiative: The Open Archives Initiative (OAI) develops and promotes interoperability standards that aim to facilitate the efficient dissemination, sharing, and reuse of web-based content. OAI-ORE work is supported by the Andrew W. Mellon Foundation, Microsoft Corporation, and the National Science Foundation (IIS-0430906). More information is available at http://www.openarchives.org.

Fedora-Muppet Mash-up at the University of Maryland

College Park, MarylandOctober 30, 2007

The Office of Digital Collections and Research (http://www.lib.umd.edu/digital/) at the University of Maryland Library began implementing Fedora to make their digital resources more accessible in January 2005. The University of Maryland Libraries (http://www.lib.umd.edu/), like many academic libraries, include not only familiar books and journals of the general collections, but many rare and unique materials.

Among those unique digital collections using Fedora disseminators for their objects is the Jim Henson Works (http://www.lib.umd.edu/digital/henson/). This collection is curated by the Michelle Smith Performing Arts Library and spans 35 years of Henson's groundbreaking work in television and film. In collaboration with the Disney Corporation, Jim Henson Works makes over 70 digital videos from Henson's career available to UM's community of students, scholars, and visitors. Fedora programmer Paul Hammer explains, "Fedora makes it possible to ingest a collection and maintain rights on individual items or objects. Fedora gives the go-ahead to a Real Server to stream rich media."

Muradora: A Web-based Repository Supporting Federated Identity and Flexible Access Control

Sydney, AustraliaOctober 15, 2007

The DRAMA (Digital Repository Authorization Middleware Architecture) team at Macquarie University in Sydney, Australia is pleased to announce the V1.0 release of Muradora, an easy to use repository application that supports federated identity (via Shibboleth authentication) and flexible authorization (using XACML). Muradora leverages the modularity, flexibility and scalability of the well-known Fedora repository.

Muradora's unique vision is one where Fedora forms the core back-end repository, while different front-end applications (such as portlets or standalone web interfaces) can all talk to the same instance of Fedora, and yet maintain a consistent approach to access control.

Muradora's key features are:

  • "Out-of-the-box" or customized deployment options
  • Intuitive access control editor allows end-users to specify their own access control criteria without editing any XML.
  • Hierarchical enforcement of access control policies. Access control can be set at the collection level, object level or datastream level.
  • Metadata input and validation for any well-formed metadata schema using XForms (a W3C standard). New metadata schemas can be supported via XForms scripts (no Muradora code modification required).
  • Flexible and extensible architecture based on the well known Java Spring enterprise framework.
  • Multiple deployments of Muradora (each customized for their own specific purpose) can talk to the one instance of Fedora.
  • Freely available as open source software (Apache 2 license). All dependent software is also open source.

Muradora utilises the new Digital Repository Authorization Middleware Architecture (DRAMA Auth/Z Suite). It consists of the following components:

  • Extended XACML support with a native XML database (DB XML) for efficient storing and querying of XACML policies. There is also a new hierarchical policy combination algorithm to support hierarchical enforcement while still allowing for fine-grained access control. These extended XACML features can be used by any XACML-aware application, especially those requiring better management of their policies.
  • Pluggable and extensible authorization infrastructure for Fedora. This new architecture utilizes an interceptor pattern to remove embedded authorization logic inside Fedora and allows new authorization requirements to be added to the system without modifying any code inside Fedora.
  • Support for federated identity with Shibboleth. The actual Shibboleth authentication is done on the Fedora server itself. This is different to the common approach of having the web interface handle Shibboleth authentication which would prevent multiple web interfaces talking to the same Fedora instance. Again this module is pluggable and can be deployed on top of Fedora without any code modification. It can also be used in conjunction with existing Fedora authentication modules.

Muradora and DRAMA Auth/Z suite can be downloaded separately and installed together by following the deployment guide at (http://www.muradora.org).

However, due to configuration flexibility and the large number of components, this installation method should be attempted only by experienced Fedora administrators.

For other users, we recommend our Live DVD which integrates all necessary components for an "out-of-the-box" repository. The Live DVD can be used to try Muradora by booting the system from the DVD and running the pre-installed system directly from the DVD (no changes are made to the host computer's hard disk). Alternatively, the Live DVD can install Muradora on a server following an easy installation procedure that is based on Ubuntu Linux Distribution. Muradora Live DVD can be downloaded from http://www.muradora.org/software.

Cultural Heritage, Learning and Research at UPEI

Prince Edward Island, CanadaSeptember 21, 2007

The “Islandora” vision, as Mark Leggott, UPEI University Librarian has dubbed the Fedora-UPEI Project, has an ambitious set of goals. He arrived at the name inspired by Che Nyguen's earlier Sept. 20, 2007 presentation to a group of Canadian Maritime librarians, archivists, and developers at the University of Prince Edward Island (UPEI) about security issues and the turnkey GUI for Fedora repository federated identity and flexible access control system - Muradora.

Leggott and his UPEI team aim to create a seamless digital repository system that is integrated into their users' environments and contexts. They will integrate the Fedora digital repository system into primary campus systems using Drupal, a proprietary content management system, Moodle, Groupwise and Open Office. They will also provide support for “landscapes” tailored for administrative, learning, and research at UPEI.

People on the move: A Fedora-based Open Access Repository To Provide a World of Information on Forced Migration

Ithaca, New YorkSeptember 10, 2007

Anyone who has put a web site together about an interesting topic has seen its content expand in proportion to interest and use. Good information tends to become more complex over time as web site displays, interactive features, new kinds of content, web services, and access to multiple data storage facilities are added. Management of even modest online information facilities can end up being perceived by users as a patchwork of access and preservation — elegant pieces cleverly stitched together without an plan for how the information will persist — a liability for those who may need it most.

The Open Access Repository System (OARS) Project has plans to migrate just such a collection of significant, well-used, and yet fragmented resources from the Forced Migration Online (FMO) Digital Library, a digital repository of scholarly resources based at the University of Oxford’s Refugee Studies Centre, to an open source platform based on Fedora in the next two years. With funding from JISC, the OARS repository will be the largest on its subject area in the world representing a unique and expanding collection of resources highly valued by the user community it serves. The OARS repository will improve management, and will also interoperate with other global open access systems, as well as with the University of Oxford’s institutional repository. The repository’s long-term preservation will be ensured by compliance with JISC Information Environment open source software and open standards. Ultimately, the new repository will help create an information environment about forced migration that is discoverable and accessible to a much wider community of users and contributors.

Force Migration Online (FMO) contains regional resources, multimedia, journals handbooks and guidelines and working papers that address what happens when people have to leave their homes or homelands to escape from political or natural disasters. FMO uses the International Association for the Study of Forced Migration (IASFM) definition for forced migration: “A general term that refers to the movements of refugees and internally displaced people (people displaced by conflicts) as well as people displaced by natural or environmental disasters, chemical or nuclear disasters, famine, or development projects.”

The Oxford Research Archive (ORA) team are also using the Fedora repository system for the construction of the University of Oxford’s institutional repository. The ORA team has developed an open source management and search interface for Fedora. The OARS Project will develop a browser–based management and search interface for their Fedora–based repository based on the ORA work and in compliance with ORA open standards.

For more information on the OARS Project contact Mike Cave, Co-Director or Sean Loughna, Co-Director.

Colorado Alliance Seeks Proposals for User Interface Design and Development

Denver, ColoradoAugust 16, 2007

The Colorado Alliance of Research Libraries (The Alliance) is a consortium of 11 partner libraries including the Denver Public Library. The Alliance shares development, costs, servers, and personnel.

The Alliance is currently seeking proposals for the design, development, and integration of a robust user interface for its Alliance Digital Repository service. The interface will provide a customizable "look and feel" to the ADR's initial discovery and access portal, encompassing the searching, browsing, and viewing actions related to digital content, including jpegs, pdfs, xml documents, and audio and video files. The interface will bring together multiple software platforms (Fedora,
