Same Cubicle, New Title, New Challenges

Here is a bit of personal news to report. Tom Sanville, OhioLINK’s executive director, announced today that I am changing roles at OhioLINK. Here is what he said:

I’m pleased to announce that Peter Murray will assume the position of Assistant Director, New Service Development effective immediately. In light of the formation of 13 task forces to pursue investigation of our strategic priorities it is critical that we have a skilled OhioLINK staff member with primary responsibility to analyze, recommend, and coordinate plans for the introduction and use of new information technologies and services by OhioLINK and its member institutions. Through Peter’s tracking and contact with information and library hardware, software, and database vendors, he will provide leadership and support to the OhioLINK staff, committees, task forces and other planning groups.

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.)

Scripted Searches for Java Code in Popular Source Code Search Engines

Sometimes the best way to solve a programming problem is to see how others have done the same thing. When that happens, having immediate access to the various search engines helps get you back on track quickly. Here are OpenSearch plug-ins (suitable for Firefox and MSIE7) that will search the Java code in five of the more popular source code search engines.

Getting Around Drupal’s Prohibition of @ Characters in User Ids

A while back we created an LDAP directory to consolidate account information for various back-room services, and when we created it we decided to use the individual’s e-mail address as the account identifier (uid in LDAP-speak). It seemed like the logical thing to do — it is something that the user knows and it is a cheap and easy way to assume that the account identifiers will be unique. This is not uncommon for many internet services, of course.
