Using DOI's with OJS

[AndyP]

How do I add DOIs to articles in OJS?

[asmecher]

Hi Andy,

The current release of OJS (2.1.1) only supports DOIs as part of the CrossRef export plugin; the next release will generate DOIs as part of the article metadata, given a journal DOI prefix.

Hi Alex

Is the DOI automatically generated for each article using the journal DOI as a starting point or do we need to enter this in the public identifier section for each article.

Thanks

Andy

Hi Andy,

The DOI is generated automatically, given a DOI prefix; we may be adding support for user-entered DOIs or alternate DOI generation schemes in a future release.

what's the difference in Setup:Details between journal initials and journal abbreviation - is one of these used in generating the DOI?

[asmecher]

Hi Andy,

The initials are used for generating the prefix; the abbreviated title appears in the CrossRef export as the "abbrev_title". (The abbreviated title is not used elsewhere, so we may consider using the initials there as well.)

Am I right in thinking that with the current version of OJS, that there is no way to configure the format of the generated doi?

For example, a doi is generated using the <item-number> to give

10.1558/blth.v4i2.689

Ideally I'd like to use the starting page number of the article instead of the item number. Could this be done using PHP?

Or will this be a possibility in a future release?

[asmecher]

Hi Chris,

We'll hopefully be adding more flexibility in a future release. For the current release, you'll need to modify the CrossRef plugin (plugins/importexport/crossref) to change the way a DOI is generated; if you need more details, I can provide.

Hi Alec,

If you could supply the details for modifying the plugin, that would be great.

My concern is that the page numbers are stored in the format 00-00. Is there a way of distinguishing between the start page of an article and the final page, so that the doi number that is generated ends with the start page number as the last "node" of the doi.

[asmecher]

Hi Chris,

In OJS 2.1.1, the DOI is generated in plugins/importexport/crossref/CrossRefExportPlugin.inc.php in the generateDOI function:

Code: Select all

function generateDOI(&$journal, &$issue, &$section, &$article) {
    return $journal->getSetting('doiPrefix').'/'.strtolower($journal->getSetting('journalInitials')).'.v'.$issue->getVolume().'i'.$issue->getNumber().'.'.$article->getArticleId();
}

You can modify this by adding a page number fetch using the $article->getPages call.

... In OJS 2.1.1, the DOI is generated in plugins/importexport/crossref/CrossRefExportPlugin.inc.php in the generateDOI function

I am trying to remove the ".v" and "i" part of the assigned DOI and would be grateful for any hints where this function (or equivalent) is located in OJS 2.2.

[istoyanov]

I suppose that the code of the CrossRef import-export plug-in has significantly changed since February 2007 and I was unable to locate any of the mentioned functions in the files, so I'd greatly appreciate any pointers on this issue. The goal is to have a quick hack to completely remove the issue part (including the associated character "i") and the "v" character (but not the volume number and the dot between it and the journal abbreviation) from the automatically generated DOI.

[asmecher]

Hi istoyanov,

The getDOI() function is currently located in classes/article/PublishedArticle.inc.php. (It was previously located in the CrossRef plugin.)
