This plugin allows references and citations in your posts. It’s only a beta version, so if you find issues or if you think it lacks some features, please contact me.
To use it, simply add your reference using a shortcode you can choose (‘jref’ by default), and a few attributes (always use lowercase):
<ul>
<li>title (mandatory)</li>
<li>author</li>
<li>date</li>
<li>url</li>
<li>editor</li>
<li>page</li>
<li>lang</li>
<li>readon</li>
</ul>
There are no specific controls on the content of those attributes, you may add any text you want. Only ‘title’ is mandatory. All attributes roles are easy to understand; ‘page’ is for a book (but can be used for any content), ‘readon’ is the date you last consult the reference.
Again, in this first release, there’s no specific control or action triggered by attribute’s content (like verifying the format, or linking to an archive site). Maybe in a future release…
A list of all references will be added at the end of the post.
Here are some examples:
<ul>
<li>[jref]url=http://geba.fr|date=janv 2017|title=The Title.|author=Janiko|lang=FR|editor=geba.fr|page=p.5[/jref]</li>
<li>[jref name=’numref’]url=http://geba.fr|date=janv 2017|title=The Title.|author=Janiko|lang=FR|editor=geba.fr|page=p.5[/jref]</li>
<li>[jref name=’numref’ /]</li>
</ul>
You can optionnaly add a name to the citation, so you can reuse it in your post. Important note: the displayed attributes will be the attributes of the FIRST reference with that name. Any other attribute will be ignored.

The goal of this plugin is to properly indicate inline citations by using the <code>q</code> HTML element in the Format toolbar of the block editor. It helps to make your website compliant to accessibility criteria. It is especially the case for the European Accessibility Act and in some countries like <a href="https://accessibilite.numerique.gouv.fr/methode/criteres-et-tests/#9.4.1" rel="nofollow ugc">in France with the RGAA criteria 9.4 which ask to properly indicate inline citations</a>.
It is always appropriate to use the <code>q</code> element for any inline quotes. This HTML element helps to make sure the citation is understood by assistive technologies, by informing the user agent that the sentence is a citation.
This plugin adds a dedicated <code>Inline Quote</code> format button in the formatting toolbar of the block editor.
