Digital object identifier
July 6, 2022
The digital object identifier, known in English as digital object identifier and abbreviated DOI and DOI, is a permanent link in the form of an alphanumeric code that uniquely identifies an electronic content. This specific piece of intellectual content can be a scientific article, an image, a book, a song or another, as long as it is an object in the digital environment. A common way to use the DOI system is to give scientific publications a specific number that anyone can use to locate the cited article through the Internet. Unlike the URL system, used in web pages, the DOI system does not change over time, even if the article is relocated to a different address, since it carries the information incorporated in the form of metadata. The functioning of the DOI is due to the collaboration of three types of organizations: International DOI Foundation: It is in charge of the management and promotion of the brand's standards. Corporation for National Research Initiatives: American non-profit association aimed at promoting the development of information and communication technologies in the field of scientific research and which is responsible for developing and maintaining the entire system so that the DOI run correctly. Registration agencies: They allow publishers to obtain a DOI for their publications under the criteria of the International DOI Foundation. Some registry agencies are DataCite. mEDRA and CrossRef.CrossRef is the largest registry agency and started in January 2000. It has so far 10800 members from more than 114 different countries and over 90 million registered content items; In addition, it has different tools to speed up the search for scientific information. One of the tools offered by CrossRef is the CrossRef Metadata Search which allows you to obtain, just by providing the DOI, the basic data of a publication such as title, keywords, authors and abstract, among others. Metadata can also be obtained in Bibtex and RIS format, as well as the bibliographic reference in APA, Vancouver, Chicago, MLA, IEEE and Harvard format. An example of the operation of the DOI is in Brazil, where the Platform Lattes del Conselho Nacional de Desenvolvimento Ciencia e Tecnológico (National Council for Scientific and Technological Development, CNPq) uses the DOI as a digital form of certification of the production of literature recorded by researchers in their C.V. Lattes. When a browser program finds a DOI number, it uses the prefix to find the publisher's database to access information about the book or journal, which can include catalog data, reviews, and links.
