Digital object identifier


July 6, 2022

Digital object identifier (DOI), discrete object identifier (DOI) is the main element of the DOI system designed to designate objects of information activity. This is a digital object identifier, not a digital object identifier. DOIs have been used since 2000 and are currently issued by more than 5,000 authorities (publishing houses, scientific data centers, film studios, and others). There are over 100 million DOI names and over 1.5 billion DOI publications per year. A DOI name (identifier, number) can be assigned to such objects as a publication or its part (book, book chapter, article) or element (figure, table, formula, etc.), audio and video content, data sets and databases data, material objects (DVD, paper book), people (authors, composers, publishers), organizations, etc. Requirements for the organization and management of the system, the structure of DOI names and metadata, the order of their assignment and disclosure are given in the ISO 26324:2012 standard. In the Russian Federation, the GOST R ISO 26324 standard, identical to the international one, applies.


DOIs allow you to uniquely and accurately identify an object and access detailed information about it (metadata) or directly to the object itself, if access to the object is open. The organization that assigned the DOI to an object is obliged to ensure that the link to the object and/or data about it is always operational. This means that an object that has been assigned a DOI can be found even if its location changes. At the same time, the object itself and the information associated with this object can always be added, changed or grouped in various ways and at any time by the owner of the DOI. With the help of DOI, related objects, such as versions (revisions) of an object, can also be differentiated and linked separately (see for example Crossmark by Crossref scientific publication version control system). The information contained in the DOI of an electronic document contains an indicator of its location (for example, URL), its name (title), other identifiers of the object (for example, ISBN for an electronic image of a book) and a set of data (metadata) describing it associated with the object in a structured and expandable form.
