DOI (Digital Object Identifier) is a string of numbers that is exclusively allocated to each online text. This code is linked to a web link permanently. Broken links are the biggest factor in the scientometric failure.
Resolving the broken link problem is possible only with DOI. It is, in fact, the fingerprint of your article or online text. DOI can be used as a permanent and immortal link to control all referrals and views related to an article and prevent the loss of referrals. A web-based DOI can remove all human errors in resource writing and aggregate all referrals. In addition to articles, DOI is also used for books and abstracts.
