Guidelines on DOI creation

Your DOI prefix will be assigned to your organization by the Registration Agency.

Mandatory guidelines

  • You have to assign the DOI suffix.
  • The suffix must be unique within the prefix and is case insensitive.
  • UTF-8 is the required coding.
  • If you use characters that have special meaning in URI Syntax, when you embed DOIs within URLs (for example to link the resolution system: http://dx.doi.org/10.1000/abc) you have to hexadecimal encode them. Find here the URI Syntax (http://www.ietf.org/rfc/rfc2396.txt).
Recommended guidelines

  • Your organization should adopt a DOI assignment scheme, for example including existing internal identifiers in use within your organization.
  • The suffix should be as concise as possible because DOIs will be displayed online and in print and will be re-typed by end users.
  • It is recommended not to use the following characters in DOI suffix:

    ; / ? : @ & = + $ , * " %
    # < > ' } { | \ ^ [ ] ` SPACE
