Specifications for Object Reuse and Exchange (ORE) published

ORE Logo The first production version of the Object Reuse and Exchange from the Open Archives Initiative was published today. In the words of the release announcement, ORE provides “the foundation for applications and services that can visualize, preserve, transfer, summarize, and improve access to the aggregations that people use in their daily Web interaction: including multiple page Web documents, multiple format documents in institutional repositories, scholarly data sets, and online photo and music collections.”

Revision Proposed to ORE Atom Serialization

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:

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.
