What is a DOI?<\/strong><\/h2>\n\n

The DOI is a unique<\/strong> and persistent<\/strong> identifier assigned to digital resources: scientific articles, films, reports, etc. It can be assigned to any digital object that must be differentiated from other objects. <\/p>\n\n

A DOI is an identifier and is also used to construct a persistent URL to the primary document.<\/p>\n\n

For example:<\/p>\n\n\n\n

Yacine Chitour; Guilherme Mazanti; Mario Sigalotti. Approximate and exact controllability of linear difference equations. Journal de l\u2019\u00c9cole polytechnique \u2014 Math\u00e9matiques, Tome 7 (2020), pp. 93-142. doi : 10.5802\/jep.112<\/a>.<\/p>\n<\/div>\n<\/div>\n\n

What is a DOI for<\/strong>?<\/h2>\n\n

Assigning a DOI first of all allows the digital object to be identified<\/strong> permanently and unequivocally<\/strong>. Placed in the document reference, it allows direct access to the primary source.<\/p>\n\n

This makes the citations<\/strong> of the document more reliable<\/strong>. In addition, it avoids endless URLs as DOIs are all built using the same short structure<\/strong>: <\/p>\n\n

The prefix identifies the registrant to the registration agency. The suffix identifies the document.<\/p>\n\n

And finally, the Inist-CNRS has published a very clear example of identifier assignment, available here: https:\/\/doranum.fr\/identifiants-perennes-pid\/exemple-attribution-2\/<\/u><\/a><\/p>\n\n

How to get a DOI?<\/strong><\/h2>\n\n

The publisher requests it for its publications. There are currently about ten DOI registration agencies<\/u><\/a> in the world.<\/p>\n\n

The centre Mersenne works with Crossref<\/u><\/a> for the allocation of its DOIs.<\/p>\n\n

How to create your DOIs?<\/strong><\/h2>\n\n

A DOI must be unique<\/strong> and contain only alphanumeric characters plus <\/strong>some special characters<\/strong> These include the dash ‘-‘, the underscore ‘_’, the full stop ‘.’, the semicolon ‘;’, the parentheses ‘(‘ and ‘ )’ and the slash ‘\/’. In addition, the suffixes are case insensitive<\/strong>: aif.3395 and AIF.3395 are considered identical.<\/p>\n\n

Tools exist to help create unique suffixes. For example, Crossref offers a suffix generator<\/u><\/a>, Datacite provides Fabrica<\/u><\/a>, a tool for managing DOIs.<\/p>\n\n
