The Open Archives Initiative – Object Reuse and Exchange Project has just released a white paper entitled “Compound Information Objects: The OAI-ORE Perspective” which describes the Web-centric OAI-ORE perspective on compound information objects. This document is a work in progress and was used as a discussion document in preparation for the May 2007 meeting of the OAI-ORE Technical Committee. The paper presents some crucial thinking which underpins this project and outlines a range of issues that are critical to its success.
