OAI-ORE Alpha Specifications Updated

As a result of discussions coming from the OAI-ORE open meeting in Baltimore in the first week of March, the document editors released a new version of the ORE alpha specifications (labeled “0.3″) earlier this month to coincide with the open meeting at Southampton, UK. In a message to the technical committee, Herbert Van de Sompel summarized the changes as:

  • Data Model: changes in the relationship between Resource Map and Aggregation; introduction of a solution regarding the reference in context; revised approach regarding nesting aggregations.
  • Atom serialization: Significant revision of the mapping from the ORE Model to Atom.

OAI-ORE Open Meeting, March 3 2008, Johns Hopkins University

Here is the press release describing the event:

FOR IMMEDIATE RELEASE:

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

Ithaca, NY and Los Alamos, NM, October 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 scholarly communication, research, and higher education infrastructure requires standardized approaches to identify, describe, and exchange these new outputs of scholarship.

“Using Access Data for Paper Recommendations”

Here is a pair of papers that I’d like a chance to digest at some point. The first is “Recommending Related Papers Based on Digital Library Access Records” by Stefan Pohl, Filip Radlinski, and Thorsten Joachims. According to the notes on the paper, it is to appear in proceedings of JCDL’07. The abstract:

An important goal for digital libraries is to enable researchers to more easily explore related work. While citation data is often used as an indicator of relatedness, in this paper we demonstrate that digital access records (e.g. http-server logs) can be used as indicators as well. In particular, we show that measures based on co-access provide better coverage than co-citation, that they are available much sooner, and that they are more accurate for recent papers.

A Report on Namespaces Used by OAI-PMH Repositories

I had a need for a survey of the metadata namespaces used by OAI-PMH repositories, so I wrote up a quick shell script and XSLT style sheet to parse through the list of Registered Data Providers at the OpenArchives.org website. The results of this effort are pretty interesting. Some of them:

The Intersection of the Web Architecture with Scholarly Communication

Two previous posts on dltj.org have described the OAI Object Reuse and Exchange (ORE) project and the theory behind what has become known as the ‘Web Architecture’. These two areas meet up now in this post which describes the issues surrounding the raw Web Architecture as applied to a web of scholarly communication and a basic outline of what the ORE project hopes to accomplish.

Working With the Web Architecture

As you may have noticed, the web has evolved a set of common principles that are a mix of ratified standards and ad hoc practices. The notion of a Web Architecture was codified in a W3C technical report called “Architecture of the World Wide Web” http://www.w3.org/TR/2004/REC-webarch-20041215/ or simply ‘Web Architecture.’ Those projects and protocols that align with the ‘Web Architecture’ are more likely to be picked up and used than those that do not. As a result, the OAI Object Reuse and Exchange (ORE) project seeks to provide an infrastructure for web-based information systems that exploit and enhance the Web Architecture, and therefore overlay cleanly on the existing web.

Introducing the OAI Object Reuse and Exchange Initiative

In the past few months a new group has formed to tackle the problem of representing and exchanging complex digital objects in a web-based environment. I am proud to serve on the technical committee for this group and over the next few postings I’m aiming to introduce the library community to the work of the Open Archives Initiative Object Exchange and Reuse group and seek the feedback of the wisdom of this crowd.

Google News Archive Search — Where Are the Links to Content from Libraries?

Extra! Extra! Read All About It! “Explore History as it Happened: Google News Now Has Archive Search” Extra! Extra!

In my imagination I can see and hear the herald of the newspaper carrier on the street corner barking out this call. Except, Kids These Days would probably decry the use of dead trees to carry stale news and already be reading it on their PDAs and text-messaging each other on their cell phones. As it is, I found out about it through a story on Search Engine Watch (also found in Wall Street Journal and the U.K. Guardian and the New York Times) which itself touted Google’s “200 Year News Archive Search.” It is a nice service; I look at it, though, and have to wonder about the changing — if not outright diminishing — role of libraries as couriers of information. After all, couldn’t links to resources from the user’s local library be included right there next to the commercial article suppliers? If they could, why aren’t they? And what does it mean that they are not?

A Known Citation Discovery Tool in a Library2.0 World

When it comes to seeking a full-text copy of that known-item citation, are our users asking “what have you done for me lately?” OpenURL has taken us pretty far when one starts in an online environment — a link that sends the citation elements to our favorite link resolver — but it only works when the user starts online with an OpenURL-enabled database. (We also need to set aside for the moment the need for some sort of OpenURL base resolver URL discovery tool — how does an arbitrary service know which OpenURL base resolver I want to use!) What if a user has a citation on a printed paper or from some other non-online form? Could we make their lives easier, too? Here is one way. (Thanks go out to Celeste Feather and Thomas Dowling for helping me think through the possibilities and issues.)

Automated Faceted Analysis In Google?

Has anyone else started seeing what looks to be faceted topical headings at the top of Google searches? This past weekend I was the groomsman at my brother’s wedding and had the unfortunate timing to catch a case of conjunctivitis in both eyes the day before the ceremony. (”Does your camera have red-eye reduction setting?” I asked the photographer. She seemed confused, so I continued: “How about pink-eye reduction?” She looked a little closer at my eyes, laughed, and said “That’s what Photoshop is for.”) Wanting to know more, I did what any self-respecting information-finder would do — I asked Google. And here’s what came up.
