Adds a feed for exporting your data using the DOAJ article XML schema.
If mod_rewrite is enabled on your site (i.e., you have pretty URLs), you can also access the feed by appending
/feed/doaj to your URL.
The plugin assumes you have a category for each issue named "Issue #", where # is the number of the issue. The issue categories should be child categories of either an "Issues" category or of a "Volume #" category. If the former, the output won't include a volume number. If the latter, the volume number will come from the volume's category name.
Short answer: you can't.
Long answer: The DOAJ article XML schema requires language codes from ISO 639-2. WordPress only gives them in ISO 639-1 (using
bloginfo('language');). So for now, the "eng" language code is hard coded into the template. If you need to change this, edit the file "doaj-template.php" in the plugin's directory, replacing the four instances of "eng" with the three-letter code for the language of your choice.
