HISTORY, FACTS
In 1998, with the participation of major international publishers, including the publishing house John Wiley & Sons, the International Foundation DOI (International DOI Foundation - IDF) was established. In 2000, the first identifiers for scientific articles were registered, and in 2012 DOI was adopted as the international standard ISO 26324: 2012 "Information and documentation. System of digital identifiers of objects ". Nowadays, DOI technology has become firmly established in the practice of scientific publishers: more than 7,000 organizations assign DOI to their materials, more than 20,000 DOI prefixes have been registered. Digital IDs are assigned to more than 130 million objects, which are recorded over 5 billion transitions by using DOI.
ASSIGNMENT OF DOI
DOI is assigned by registration agencies. At the moment there are 10 registration agencies. For scientific content DOI is assigned by the Crossref registration agency. To assign DOI scientific materials, publishers must sign a contract with the Publishers International Linking Association (PILA), the International Publishers Association, the incoming administrative structure of the Crossref registration agency. The contract allows an annual registration assembly, which is obligatory for a one-time payment. Its size starts at $ 275 and depends on the scale of the organization and other parameters, and the organization will have to pay $ 30 for $ 25 (bank commission). Information about payments on the official website of Crossref is available at the following link
Also, publishers may conclude a contract for the assignment of DOI with Sponsor organization Crossref (Sponsor), which is authorized for administrative, financial, billing, technical issues representing publishers (publications, universities, scientific organizations) in PILA. Such a contract is equivalent to a direct contract if the Sponsorship Organization undertakes to provide an individual prefix for the publisher (publication, university, scientific organization), however, as a rule, the annual membership fee is lower than the direct contract with Crossref.
Please note that for publishers (publications, universities, scientific organizations) it is extremely important to have your own DOI prefix and you have no rights to register third-party organizations. This can lead to a loss of affiliation with the magazine.
The publishing house "Internauka" is the official partner (Sponsoring Member) of Crossref in Europe with the status of Sponsoring Member (statement from the register Sponsoring member) and provides individual DOI prefixes for publishers (publications, universities, scientific organizations)
DOI STRUCTURE
The DOI consists of two parts - a prefix and a suffix. Both the prefix and the suffix are inseparable parts of the DOI.
1. Prefix - issued by the registration agency Crossref or its sponsoring organization after signing the contract and paying the registration fee. The prefix identifies the publisher. This is a rigid structure and it is impossible to make changes to the set of figures.
2. Suffix - assigned to each object by the publisher. Typically, the suffix identifies the object, year of publication, volume, issue number, location of the object, etc. The suffix can be anything: numbers, letters, etc., except for a few prohibied.
