Is it possible to have a field auto-updated with the current date/time whenever the metadata on that item is updated?
Item updates are timestamped, the update date/time value is available through the modified() method (search for “modified” in Representations - Omeka S Developer Documentation).
For example, you can display this information in your item show page by editing your theme’s omeka/site/item/show.phtml template and add something like:
...
<?php
$dateModified = $this->i18n()->dateFormat($resource->modified(), 'medium', 'medium');
?>
<div>
<span>Mise à jour: <?php echo $dateModified; ?></span>
</div>
...
which will output:
