EBSCOhost Connection Records Found In-The-Wild

EBSCOhost Connect was announced in the spring of 2006 as near as I can recall. (I can’t find the press release about it on the EBSCO website. As close as I can come to a date is from an announcement at the Oregon School Library Information System.) After three years, I’ve finally seen an EBSCOhost Connect in Google web search results. This screencast and accompanying transcript (below) show what I’ve found.

Analysis of PubGet — An Expedited Fulltext Service for Life Science Journal Articles

In June, a new service that speeds access to life sciences literature reached a milestone. Called PubGet, it is a service that reduces the number of clicks to the full text of an article, and the milestone was activating the 50th institution using its service. Using its own proprietary “pathing engine”, it links directly to the full text on the publisher’s website. PubGet does this by understanding the link structure for each journal of each publisher and constructing the link to the full-text based on information from the citation. The PubGet service focuses on the life sciences journals indexed in PubMed — hence the play on names: PubMed to PubGet.

Collocating Serial Formats Via “Linking ISSN”

Earlier this week I received an e-mail from the director of the ISSN International Center announcing a session at the ALA Annual Conference in Anaheim to talk about the “linking ISSN”. Abbreviated ISSN-L, this is a new addition to the revised ISSN standard (ISO 3297, published last August) that allows for the collocation of separate ISSNs under a single ISSN-L. The ISSN standard now explicitly states that an ISSN is a unique identifier for a specific serial in a defined medium. In other words, separate ISSN should be assigned to each different medium version of a serial. The ISSN-L table brings these separate ISSNs together.

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.

Problems With the Web Architecture

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.
