DOI suffix policy

It was decided to use a standard for the suffix policy for all journals to create consistency. The suffix policy is called "via" or "very important article". Make sure that there are NEVER any SPACES or AMPERSANDS being generated by DOI's.

The suffix is made of the following OJS variables:

%v = volume
%i = issue
%a = article id

A dash is used to seperate them.

Therefore the suffix in the config file is:


For example a suffix for article 10 in issue 2, volume 3 is as follows:


And with a proper DOI prefix:

The article id is only generated once a submission is approved by the Editor.
