When a Kapplet is ready for use, a Kapplet user or a group of users can obtain access privileges to the Kapplet through a specialised workspace. A group of users can work only with a set of Kapplets defined by the administrator. Kapplet users keep a list of the installed Kapplets in their workspace.

Kapplets are built and maintained by users depending on their assess privileges. These privileges can be changed by the global administrator.

• User: Runs Kapplets.

• Developer: Creates Kapplets and Templates, runs Kapplets.

• Administrator: Creates Kapplets, Templates, and Workspaces; runs Kapplets and assigns privileges.

The correlation looks the following.

These privileges can be of two types: local privileges and global privileges:

• Global privileges are managed at the system-wide level and can be assigned to a group of users, where each user inherits the privilege, or to a certain user.

• Local privileges are assigned only to the user groups of a certain workspace, users inherit these privileges from the user group .
