Omeka S advanced setting: Roles, licenses and users

On how to manage roles, licenses and users.

In Omeka S installation, users accounts allow the employees to carry out various actions such as adding elements, moderate shipments, upload multimedia files, create virtual exhibitions and edit metadata. 

Users roles in Omeka S

User roles are set at the installation level and they are independent from site-specific user roles. Firstly, a user must be created for the installation and then given site roles within each site they participate. This allows you to give minimal installation-wide permissions and, simultaneously, give a wider access within specific sites. 

Types of roles 

Six types of users are defined by Omeka S, each one having different level access:

  1. Global administrator: they have full installation privileges.
  2. Supervisor: Manage users and licenses, having access to sites settings. 
  3. Editor (content expert): they can create, edit and administrate all elements.
  4. Reviewer: they can manage content, but only delete their own.
  5. Author: they can create and modify their own content.
  6. Researcher: they only have search and read privileges.

Each role is associated with the following slugs:

  • global_admin 
  • site_admin 
  • editor
  • reviewer 
  • author 
  • researcher
