It is the scientific journal that publishes the research DOI

A DOI is a unique identifier that provides a permanent link to any research you add to your profile – making it easily findable and citable. In other words, DOIs provide information on where your work can be found online.

A DOI is generated by a registration agency (Crossref) that contains an alphanumeric string beginning with “10” and a prefix of four or more numbers. The prefix is followed by a slash (/) and a suffix. The suffix is assigned by the publisher.Oct 20, 2017

Thank you to all colleagues for the valuable scientific answers with the utmost appreciation and respect for all

Good Q follwing

A Digital Object Identifier (DOI) aims to be "resolvable", usually to some form of access to the information object to which the DOI refers. This is achieved by binding the DOI to metadata about the object, such as a URL, indicating where the object can be found.

Thank you "very much" to colleagues for their effective contribution with appreciation

Informative discussion.

DOI is a unique alphanumeric string assigned by a registration agency to identify content and provide a link to its location on the Internet., also help the reader easily locate a document from citation.

International journals assign this index to articles for their identification on the Internet.

It s a way to verify the existance of an article

DOI is simply known as Digital Object Identifier . But its utility is great to prove

the originality of your work . It is available with your published article from the Journal & even your unpublished preprint ( RG ) .

A DOI (Digital Object Identifier) is a unique alphanumeric identifier applied to a specific piece of intellectual property, especially one presented in an online environment — whether that object is a book, a scientific paper, a song, an image, or something else. Unlike a conventional Web address, or URL, a DOI specifies not the location of an online object, but rather its content; a DOI is thus a "persistent" identifier, and remains associated with the object irrespective of changes in the object's Web address.

I agree with Dr. Ekhlas Hussien and Dr. Emad Hussien

A digital object identifier (DOI) is a string of numbers and letters assigned to electronic resources like online journal articles & eBooks. Not every electronic resource has a DOI. Like a barcode, this string of numbers and letters is specific to a single resource and can be used to find the object on the internet. DOIs are also used in citations, in place of a URL.

For more information about DOIs, see

http://www.crossref.org/index.html Where do I find the DOI? http://blog.apastyle.org/apastyle/digital-object-identifier-doi/

Look for the DOI (digital object identifier) on the PDF of the article or search for it on the CrossRef.org website using the Metadata Search. Be aware that not all articles have a DOI. Locate the PDF of the article. Many publishers include the DOI along with other citation information on the first page of an article

HI,

Digital Object Identifier is the expansion of DOI and it helps in identifying an article. These days most of the organizations and websites demand the DOI of an article alongside the topic of the article.

Thank you very much for all of you. Great answers and valuable fellow researchers with appreciation and respect for all.

DOI or Digital Object Identifier is an identifier to track published works.

Interesting question that provoked several valuable and informative replies from RG colleagues
