1 doi> Digital Object Identifier: overview
Norman Paskin, International DOI Foundation doi>

2 doi> International DOI Foundation Created in 1998;
supports the needs of the intellectual property community in the digital environment, by the development and promotion of the Digital Object Identifier (DOI) system as a common infrastructure for content management; controlled by a Board, elected by the members of the Foundation; activities of the Foundation are controlled by its members, operating under a legal Charter and formal By-laws; membership is open to all organizations with an interest in electronic publishing, content distribution, rights management, and related enabling technologies; membership is international. Today the foundation has over 200 companies using several million DOIs.

3 doi> Digital Object Identifier (DOI)
DOI is a system for persistent and actionable identification and interoperable exchange of intellectual property on digital networks; DOI is made up of two components, the prefix and the suffix; Value of the DOI system lies in its combination of Resolution, Metadata and Policy.

4 doi> Features of DOI Resolution - Metadata - Policy -
ensures persistence by resolving the DOI to a current associated value such as a URL; resolution may be to multiple pieces of data (multiple resolution); the Handle System is the resolution system used. Metadata - based on <indecs> activity; consistent with systems such as ONIX and MPEG-21 rdd; enables mappings between application areas consistently. Policy - provides rules and mechanisms for implementation; use of Registration agencies which operate under same rules as an operational federation.

5 doi> Benefits of DOI Actionable Identifier -
a user can use a DOI to do something; the technology, which underlies the DOI, facilitates much more complex applications than simple location finding; DOI identifies the intellectual property entity itself rather than its location. Persistent Identifier - if ownership of the entity or the rights in the entity change, the identification of that entity should not (and does not) change; the responsibility for managing the DOI changes, but not the DOI itself. Interoperable Identifier - DOI System has been designed to be able to interoperate with past, present and future technologies.

(Build 2) The RA will deposit the metadata in a metadata collection, (Build 3) and create the DOIs but submitting the DOIs and their associated data to the DOI System.

Multiple Resolution doi> Type Data Index DOI 10.XXXX/123 Syndicator - Retailer Distributor - Rights Person Trade Association Multimedia Publisher Data Aggragator - Consumer Resolution Request DOI System Metadata Collection An illustration of Multiple Resolution A customer -- consumer, aggregators, syndicator, etc., -- (Build 1) who encounters a DOI on a Web page (or in some other resource), (Build 2) can query the DOI System and/or a Metadata Collection (or perhaps the DOI client will query the metadata collection behind the scenes as illustrated here), (Build 3) and retrieve an index listing of the information stored with that DOI, which in turn enables the customer to choose from any number of options (purchase, examine, read about, etc.,) related to that DOI.

8 The DOI System – Open Standards
The DOI brings together two major fundamentals which ensure long term extensibility and interoperability of various types of intellectual property within various systems, wireless applications, broadcasting and Internet applications: The Handle System - a distributed, scalable system based on open protocols, which manages digital intellectual property as first class entities. Both the Handle System resolution and the DOI metadata components are structured, consistent, and manageable so it is possible to apply DOIs to any content and to develop further tools for content management. The <indecs> Framework - a broad multi-industry effort which defined principles for metadata and how existing metadata systems can be mapped into a standard interoperable form. On an open standards basis, this framework is currently being expanded to create <indecs>rdd, a Rights Data Dictionary for multimedia rights management, because unlike kernel metadata, rights data is transient and dynamic.

9 The DOI System – Standards Tracking
The DOI is one component of a fast developing technological infrastructure for the management of intellectual property in the network environment. There are many different players involved in the development of that infrastructure, ranging from technical organizations to the "content industries" themselves. WIPO (World Intellectual Property Organization) ISO (International Standards Organization) NISO (National Information Standards Organization) IETF (Internet Engineering Task Force) W3C (World Wide Web Consortium) OeBF (Open eBook Forum) MPEG 21 (Moving Picture Experts Group) A significant element of the work of the IDF lies in tracking standards developments in related areas, understanding their significance to the context within which the DOI will operate, and establishing working relationships with organizations and projects to ensure that appropriate co-operation is fostered to mutual benefit (and that parallel developments do not remain in ignorance of one another).

10 doi> How to Get Started
Become a member of IDF and participate in working groups, receive white papers and internal membership reports and meeting briefings. More information can be found at To become a Registration Agency, please see more information at To obtain a DOI Prefix you need to apply to a DOI Registration Agency or the IDF. More information can be found at For further general information, please see the DOI Handbook at and
