If a Role were to win a Grammy or an Oscar or some other ego-feeding popularity contest, it better remember to thank all its permissions groupies during the acceptance speech, because they’re the ones doing the real work. The role is just the pretty face, so to speak.
Roles collect permissions that define a particular function, according to a particular scope. Roles collect permissions, and Users are assigned to Roles.
Take a Message Board Administrator Role, for example. A Role with that name should have permissions relevant to the specific Message Board portlets delegated to it. Users with this Role inherit the permissions collected underneath the umbrella of the Role.
In addition to regular Roles, Site Roles, and Organization Roles, there are also Teams. Teams can be created by site administrators within a specific Site. The permissions granted to a Team are defined and applied only within the Team’s site. The permissions defined by regular, Site, and Organization Roles, by contrast, are defined at the global level, although they are applied to different scopes.
- Regular role
- Permissions are defined at the global level and are applied at the global scope.
- Site role
- Permissions are defined at the global level and are applied to one specific Site.
- Organization role
- Permissions are defined at the global level and are applied to one specific Organization.
- Permissions are defined within a specific Site and are assigned within that specific Site.
A Web Content Folder contains Web Content articles. The Web Content Folder is an asset container, and the Web Content Article is an asset. It’s possible to give a Role permission to delete an asset container without giving the Role permission to delete individual assets. In that case, beware: if a Role assignee deletes an asset container with individual assets in it, the individual assets themselves are deleted as well.
Besides Web Content Folders, examples of asset containers include Bookmarks Folders, Message Boards Categories, Wiki Nodes, and Documents and Media Folders.
You might not need to create a Role for a certain functionality. Liferay provides many pre-configured Roles for your convenience.
In the Roles Application appears a list of all the Roles in Liferay, by scope.
These are some of the pre-configured regular Roles:
- Guest: The Guest role is assigned to unauthenticated users and grants the lowest-level permissions.
- User: The User role is assigned to authenticated Users and grants basic permissions (mostly Add to Page permissions for their own Sites).
- Power User: The Power User Role grants more permissions than the User Role. It’s an extension point for distinguishing regular Users from more privileged Users. For example, you can set things up so that only Power Users have personal sites.
- Administrator: The administrator Role grants permission manage the entire portal, including global portal settings and individual Sites, Organizations, and Users.
These are some of the pre-configured site roles:
- Site Member: The Site Member Role grants basic privileges within a Site, such as permission to visit the Site’s private pages.
- Site Administrator: The Site Administrator Role grants permission to manage almost all aspects of a Site including site content, site memberships, and site settings. Site Administrators cannot delete the membership of or remove roles from other Site Administrators or Site Owners. They also cannot assign other Users as Site Administrators or Site Owners.
- Site Owner: The Site Owner Role is the same as the Site Administrator Role except that it grants permission to manage all aspects of a Site, including permission to delete the membership of or remove Roles from Site Administrators or other Site Owners. They can assign other users as Site Administrators or Site Owners.
These are some of the pre-configured organization roles:
- Organization User: The Organization User role grants basic privileges within an Organization. If the Organization has an attached Site, the Organization User Role implicitly grants the Site member Role within the attached Site.
- Organization Administrator: The Organization Administrator Role grants permission to manage almost all aspects of an Organization including the Organization’s Users and the Organization’s Site (if it exists). Organization Administrators cannot delete the membership of or remove Roles from other Organization Administrators or Organization Owners. They also cannot assign other Users as Organization Administrators or Organization Owners.
- Organization Owner: The Organization Owner Role is the same as the Organization Administrator Role except that it grants permission to manage all aspects of an Organization, including permission to delete the membership of or remove Roles from Organization Administrators or other Organization Owners. They can assign other Users as Organization Administrators or Organization Owners.
Roles, and the permissions granted with their assignment, are foundational components in Liferay. Understanding their uses and configuration enhances your ability to configure Liferay DXP to suit your organizational needs.
