The Digital Object Identifier System

Welcome to the DOI® System

The Digital Object Identifier (DOI^®) System is for identifying content objects in the digital environment. DOI^® names are assigned to any entity for use on digital networks. They are used to provide current information, including where they (or information about them) can be found on the Internet. Information about a digital object may change over time, including where to find it, but its DOI name will not change.

The DOI System provides a framework for persistent identification, managing intellectual content, managing metadata, linking customers with content suppliers, facilitating electronic commerce, and enabling automated management of media. DOI names can be used for any form of management of any data, whether commercial or non-commercial. The DOI System is an ISO International Standard.

The system is managed by the International DOI Foundation, an open membership consortium including both commercial and non-commercial partners. Over 55 million DOI names have been assigned by DOI System Registration Agencies in the US, Australasia, and Europe.

Using DOI names as identifiers makes managing intellectual property in a networked environment much easier and more convenient, and allows the construction of automated services and transactions.

To learn more about DOI names, see the Overviews, and begin with the Introductory Overview and Introductory Slide Presentation. The Factsheets, including "Managing Data Relationships Using DOI Resolution" and "DOI System and Standard Identifier Schemes" discuss key topics about the system. For the most complete description of all aspects of DOI System technology and policy, consult the DOI^® Handbook.
