By Daniel Berthereau Add tags and tagging form to any resource to create uncontrolled vocabularies and tag clouds.

Folksonomy (module for Omeka S)

New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.

Folksonomy is a module for Omeka S that allows to add uncontrolled topics to any resource (item, item set, media) and that allows visitors to tag them in order to create a folksonomy or a tag cloud.

Tags can be added with or without captcha and approbation. Once approved, public tags become normal tags. Tag creation and approbation are managed via roles. They can be imported by the module CSV Import like in Omeka Classic.

This Omeka S module is a full and improved rewrite of the Tagging plugin for Omeka Classic.


First, install the two optional modules Generic and Blocks Disposition.

Uncompress files and rename module folder "Folksonomy".

Then install it like any other Omeka module and follow the config instructions.

The Folksonomy module can use Omeka ReCaptchas. You need to get keys to this service and set them in the general preferences.

The tags (names) and the taggings (approval, reject) are manageable directly in the admin view.

Display Tagging Form

The tags and the tagging form are displayed automatically on item set, item or media pages. To manage the display more precisely, use the module Blocks Disposition, or use the helpers to display them in your theme. The templates are customizable in the theme. Rights and visibility are automatically managed.

  • Important

The form uses jquery. It’s enabled by default in the admin view, but may be not available in some themes.

Internal Notes

The tables added to the database support the possibility for each user to tag each resource and to manage his/her own taggings, but currently, the forms manage only one tagging for all users for a tag for one resource, because Omeka is document-oriented.


Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
