Abstract

The International DOI Foundation (IDF) recently published the third edition of its DOI Handbook, which sets the scene for DOI's expansion into much wider applications. Edition 3 is not simply an updated user guide. A great deal has happened in the underlying technologies and in the practical deployment and development of DOIs (Digital Object Identifiers) since the last edition was published a year ago. Much of the program of technical work foreseen at the inception of DOIs has now been completed. The initial simple implementation of DOI as a persistent name linked to redirection continues to grow, with approaching ten million DOIs assigned from several hundred organisations through a number of Registration Agencies in USA, Europe, and Australasia, supporting large scale business uses. Implementations of more sophisticated applications (offering associated services) have been developing well but on a smaller scale: a framework for building these has been completed as part of the latest release and promises to stimulate a new wave of growth. From its original starting point in text publishing, there has been gradual embrace by a number of communities: these include national libraries (a consortium of national libraries recently joined the IDF); government documentation (with the appointment of TSO The Stationery Office in the UK as a DOI agency and the announced intention of the EC Office of Publications to use DOIs); non-English language markets (France, Germany, Spain, Italy, Korea). However implementations in non-text sectors have been far slower to develop, though several are now under discussion. The DOI community can point to several significant achievements over the past few years: * A practical successful open implementation of naming objects, treating content as information objects, not simply packets of bits; * The IDF's role in co-sponsoring, championing, and now implementing the <indecs>T framework as a semantic tool for structured metadata - an essential step for treating content as information in Semantic-Web-like applications; * A template for building advanced applications, connecting resolution and metadata technologies, and offering hooks to web services and similar applications; * The development of a policy framework that allows multiple communities autonomy; * The practical implementation of DOIs with emerging related standards such as the OpenURL framework in contextual linking.
A number of issues remain to be solved. In the main these are no longer technical in nature, but more concerned with perception and outreach to other communities. They include: correctly positioning the DOI in the standards community as a practical implementation (based on standards, but more than standards); offering the benefits of DOI to other communities working in related identifier development whilst allowing them to remain largely autonomous; demonstrating how DOIs can complement, rather than compete with, other activities; and ensuring that a sustainable long-term infrastructure for any application (commercial and non-commercial alike) is in place. Persistent, actionable identifiers with a fully managed sustainable infrastructure are not appropriate for every activity; but they are suitable for many, and where they are used, the key to providing a successful and widely adopted system is encouraging economy of scale (and so, where possible, convergence with other related efforts), flexibility of use, and a low barrier to use. DOI is well on the way to providing this, but not yet guaranteed of success without the further effort that is now being applied.
