Digital Object Identifier DOI is both a unique identifier of a piece of digital content AND a system to access that content digitally. Persistent object identifier. DOI system has two main parts: (the identifier and a directory system) and a third logical component, a database. Developed by AAP (Association of American Publishers), now managed by International DOI Foundation.
Constructing a DOI • Standard for persistent object identification. • DOI is a ‘dumb’ (opaque)number that identifies a digital object: • Example: 10.1063/S000369519903216 • 10 Registration Agency Prefix • 1063 Publisher Prefix • S000369519903216 Suffix (Publisher-assigned ID) • The DOI and the URL pointing to the digital object, is registered with the service provider: • 10.1006/rwei.1999.0001| http://www.sciencedirect.com/science/article/pii/B0122267656000013
DOI Resolution • DOI Handle System (developed by CNRI -Corporation for National Research Initiatives). • Retrieval of object: • link is sent to central Handle directory where current Web address is stored • location is sent back to browser with special message to redirect to address, e.g: • http://dx.doi.org/10.1006/rwei.1999.0001redirects to http://www.sciencedirect.com/science/article/pii/B0122267656000013
A DOI Registration Agency • General purpose: “to promote the development and cooperative use of new and innovative technologies to speed and facilitate scholarly research.” • Specific mandate: be the citation linking backbone for all scholarly information in electronic form • Began in 1999 with major publishers forming non-profit PILA (Publishers International Linking Association), which operates CrossRef. • Members: 4865 publishers, 2005 libraries • 2013: a BILLION DOI resolutions • Averages 2 million metadata queries/day • Three major resolution-related services: depositing metadata including DOIs, submission of article references for the purpose of obtaining DOI, creation of links using DOIs.
