Presentation Summary: “Cross-Repository Semantic Interoperability: the MIT SIMILE Project”

Posted on by

Richard Rodgers presented this talk based on the work of he and MacKenzie Smith in the Digital Library Research Group at MIT. The original abstract of the presentation was:

Many questions are raised as previously unreachable digital content is found in and among new repositories–is each repository an island or a separately searchable resource? SIMILE (Semantic Interoperability of Metadata and Information in Unlike Environments) has developed an extensive ‘tool chain’ for gathering and manipulating data assets. Richard Rodgers and MacKenzie Smith, MIT, will demonstrate how tools developed by the SIMILE project can be used as powerful instruments for the federation, discovery, exploration, and curation of metadata.

Presentation Summary: “MPTStore: Implementing a fast, scalable, and stable RDBMS-backed triplestore for Fedora and the NSDL”

Chris Wilper gave this presentation on behalf of the work that he and Aaron Birkland did to improve the performance of the Fedora Resource Index.

Version 2.0 of the Fedora digital object repository software added a feature called the Resource Index (RI). Based on Resource Description Framework (RDF) triples, the RI provided quick access to relationships between objects as well as to the descriptive elements of the object itself. After about two years of use using the Kowari software, the RI has pointed to a number of challenges for “triplestores”: scalability (few triplestores are designed for greater than 100 million triples); performance; and stability (frequent “rebuilds”).

Open Source for Open Repositories — New Models for Software Development and Sustainability

This is a summary of a presentation by James L. Hilton, Vice President and CIO of University of Virginia, at the opening keynote session of Open Repositories 2007. I tried to capture the esessence of his presentation, and omissions, contradictions, and inaccuracies in this summary are likely mine and not that of the presenter.

Setting the stage

This is a moment in which institutions may be willing to invest in open source development in a systematic way (as opposed to what could currently be characterized as an ad hoc fashion) driven by these factors:

A Vision for FEDORA’s Future, an Implementation Plan to Get There, and a Project Update

This morning, Sandy Payette of Cornell University and FEDORA project co-director, gave an update on the FEDORA project including a statement of a vision for FEDORA’s future, information about the emerging FEDORA Commons non-profit, and a status report/roadmap for the software itself. Below is a summary based on my notes of Sandy’s comments and slide content.

Vision for FEDORA’s Future

From her perspective, Sandy sees many kinds of projects using FEDORA, and she sees them fall into these general categories: Scholarly Workbenches — capturing, managing and publishing the process of scholarship; Linking Data and Publications — complex objects built up of relationships with different types of internal and external objects; Reviews and Annotations of Objects — blogs and wikis on top of information spaces; collaborations surrounding a repository object; and Museum Exhibits with K-12 Lesson Plans.

Blogging About Open Repositories 2007? Use the ‘icor2007′ tag.

Are you blogging the Open Repositories conference in San Antonio this week? Are you posting pictures to Flickr?

if so, may I suggest using the ‘icor2007′ tag when posting your content. When doing so, the HitchHikr service will aggregate content from Technorati and Flickr based on that tag. (Why not simply “or2007″? — it looks like that tag picks up extra cruft in a non LATIN-1 character set.)

Building an Institutional Repository Interface Using EJB3 and JBoss Seam

Posted on by

This tour is designed to show the overall architecture of a FEDORA digital object repository application within the JBoss Seam framework while at the same time pointing out individual design decisions and extension points that are specific to the Ohio Digital Resource Commons application. Geared towards software developers, a familiarity with Java Servlet programming is assumed, although not required. Knowledge of JBoss Seam, Hibernate/Java Persistence API, EJB3 and Java EE would be helpful but not required; brief explanations of core concepts of these technologies are included in this tour.

The tour is based on revision 709 of /drc/trunk and was last updated on 18-Jan-2007.

Sandy Payette, Co-Director of the Fedora Project and Researcher in the Cornell Information Science department, announced a tentative date for the release 2.2 of the FEDORA digital object repository.

The Fedora development team would like to announce that Fedora 2.2 will be released on Friday, January 19, 2007.

This new release will contain many significant new features and enhancements, including [numbers added to the original for the sake of subsequent commentary]:

  1. Fedora repository is now a web application (.war) that can be installed in any container
  2. Fedora authentication has been refactored to use servlet filters (no longer Tomcat realms)

Heads up! International Conference on Open Repositories (01/23/07 – 01/27/07, San Antonio, TX, US)

Open Repositories 2007 is coming up next year, and it looks to be an interesting meeting. The first day is open user group meetings for DSpace, Fedora, and Eprints, followed by general conference sessions that cover issues that cut across all of the open repository systems. This year, the user groups will partition their programs into Plenary, Technical Issues, and Management Issues and the partitions will be staggered so that IT managers can attend all plenary sessions, technical staff can attend all technical sessions, etc.
