Ron Murray and Barbara Tillett, both from the Library of Congress, are presenting their research in thinking about bibliographic information as networks of interrelated nodes at ALA Annual. This is a continuation of their “paper tool” work which was presented at the Library of Congress last year.
Last Friday, Herbert Van de Sompel posted a message to various mailing lists about a proposed revision to the serialization of OAI-ORE into Atom. The proposal by Michael Nelson, Robert Sanderson, and Herbert has two key components:
- To express an ORE Aggregation at the level of an Atom Entry, rather than (as in the current draft) at the level of an Atom Feed
- To convey ORE-specific relationships types using add-ons/extensions, rather than by making ORE-specific interpretations of pre-existing Atom relationship types
Here is the text of Herbert’s message:

Open Archives Initiative Announces U.K. Public Meeting on April 4, 2008 for European Release of Object Reuse and Exchange Specifications
Ithaca, NY and Los Alamos, NM, January 21, 2008 – As a result of initiatives in eScholarship, the format of scholarly communication, and the process that underlies it, are becoming increasingly expressive and complex. The resulting new artifacts of scholarship are aggregations composed of multiple media types, links to data, and to applications that allow interaction with that data. The success of these innovations depends on standard methods to identify, describe, and exchange these new forms scholarly communication.
Last night, Herbert Van de Sompel announced the availability of the draft specifications and user guide for Object Reuse and Exchange (ORE). This effort, under the auspices of the Open Archives Initiative (OAI), seeks to define a standard for the description and exchange of aggregations of web resources.
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.
The Technical Committee and Liaison Group of the OAI Object Reuse and Exchange effort met last week in New York City to hammer out face-to-face some of the last remaining issues before work could begin on a draft specifications document. In preparation for that meeting, we worked on a white paper that is officially called “Compound Information Objects: The OAI-ORE Perspective” — but it might more accurately be called “Thoughts on Compound Documents”. The outline of the white paper looks like this:
- Introduction and Motivation
- An OAI-ORE Interoperability Layer for Compound Objects
- Exposing Logical Boundaries in the Web Graph
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
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.
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.
