DOI News

  1. DOI tools
  2. Metadata interoperability: DOI signs metadata agreement
  3. DOI develops advanced functionality, common metadata tools
  4. DOI applications continue to flourish
A number of tools to help in using DOIs are now available. More will be added as they become available. Current tools include:
  • Plug-in for Adobe Acrobat® and Acrobat Reader®: an extension to Adobe's software that uses a DOI to offer customised services specific to the document -- e.g., alert the reader to a new version of the document.
  • Server Side Resolution: scans web pages for DOI links and creates popup menus containing details of those DOIs.
  • DOI Button: JavaScript: paste or type a DOI and then resolve it, or highlight a DOI on a web page and resolve it without retyping.
  • CNRI Handle System Resolver Web Browser: plug-in extension for Internet Explorer and Netscape -- recognize DOIs and resolve them directly.
  • Protocol Handler: JavaScript functionality for Mozilla and Netscape 6 enables direct resolution of DOIs.
  • Mozilla Protocol Extender: allows users to specify behaviour when a DOI of a defined type is activated in a link.
The International DOI Foundation has joined several other major standards activities (among them GILS, ONIX, MARC21, CERIF, IEEE/LOM and Dublin Core) in committing to assign URI identifiers to all metadata elements it uses, and to support the stability, persistence, and maintenance of the identifiers. This will aid in the development of mapping infrastructures and interoperability services through a common citation mechanism. DOIs, of course, are designed from the outset for stability, persistence, and maintenance and so ideally suited to such a role. For the full text of the resolution, see http://www.cores-eu.net/interoperability/.
A number of demonstrations have shown the power of the multiple resolution functionality of DOIs -- allowing one DOI to offer several choices or services (e.g., the Adobe Acrobat example showing "latest version" options: see "DOI Plug-In for Adobe Products Demonstrated"). The International DOI Foundation has developed a common approach to allow such multiple resolution features to be offered independently by many different developers, yet maintain an underlying common logic. DOIs from many sources can be dealt with by the same mechanisms.
Part of this work leads users to access DOI metadata in a common format: we are including mappings of ONIX and the MPEG Rights Data Dictionary in the first release of a practical tool for allocating metadata to DOIs in a structured way, which will be released shortly, and will add other mappings as they become available (see earlier DOI News for information on agreements with ONIX, and IDF's work on the MPEG-21 RDD standard, now nearing completion: http://0-www.doi.org.libus.csd.mu.edu/press_release_archive.html).
This combination of multiple resolution and structured metadata -- called "Application Profiles" -- offers powerful enhanced DOI functionality and value. Working groups within IDF are now showing practical implementations of this approach, and we invite others to join us.
The biggest current DOI application, CrossRef (an association of the world's leading 180 scholarly publishers) now has 6.6 million DOIs registered from 6,900 journals, with over 2 million DOI resolutions per month. Further applications to reference works and conference reports are coming soon. For further details see http://www.crossref.org.
Content Directions, Inc. have announced agreements with Business & Legal Reports, Inc., to register DOIs for BLR's electronic and print products; with Humana Press to assign DOIs across its entire print and eBooks publishing program; and a strategic alliance with Publishing Dimensions to easily and rapidly aid publishers to assign DOIs to their electronic and print content marketed on the Internet. For further information see http://www.contentdirections.com/news.htm.
TSO is demonstrating DOI multiple resolution and interoperability across distributed legislative information sources in the Government and Legal and Publishing sectors. For further information see http://www.tso.co.uk.
These are just some of the current applications from some of our Registration Agencies.
Coming soon: news of multimedia applications, support for DOI in the library sector, and details of further Registration Agencies.

The DOI is a system for interoperably identifying and exchanging intellectual property in the digital environment. A DOI assigned to content enhances a content producer's ability to trade electronically. It provides a framework for managing content in any form at any level of granularity, for linking customers with content suppliers, for facilitating electronic commerce, and enabling automated copyright management for all types of media. The International DOI Foundation, a non-profit organization, manages development, policy and licensing of the DOI to registration agencies and technology providers and advises on usage and development of related services and technologies. The DOI system uses open standards with a standard syntax (ANSI/NISO Z39.84) and is currently used by leading international technology and content organizations.
This is a service announcement for the International Digital Object Identifier Foundation and has been prepared to increase your awareness about important developments to enable digital copyright management of intellectual property. For more information, please send your request to contact@doi.org.
