Digital object identifier


January 21, 2022

Digital Object Identifier (DOI) is a name used to uniquely identify electronic documents and other entities. DOI is a more stable method of document referencing than URL. The DOI name of a document is fixed throughout the life of the document, unlike a URL that is subject to change, such as a change in the organization of files on a web server. The DOI system can be used to locate a valid URL of the document. The DOI system is realized through the cooperation of DOI registration agencies. Their work is coordinated by the International DOI Foundation, which has developed and oversees the system. Since 2000, the DOI system has been developed and incorporated into several publishing programs. By the end of 2009, this system was in use in some 4,000 organizations, which had issued about 43 million DOI names.

DOI names

DOI name is formed from a series of symbols that are divided into two parts: prefix and suffix. The prefix indicates the registrant, and the suffix indicates the specific object. Most valid Unicode characters are allowed. No uppercase or lowercase letters are distinguished. For example, in the DOI name 10.1000 / 182, the prefix is ​​10.1000 and the suffix is ​​182.
