A + calendaring framework will allow a user to keep a personal + calendar and have several applications use it. Such + applications could be a graphical calendar client that the user + employs to schedule appointments and keep track of his time, a + <productname>Palm Pilot</productname> synchronization client, or + a simple alarm or reminder utility. A comprehensive calendaring + framework will also allow multiple users to schedule + appointments between each other; for example, a project director + may want to schedule a weekly meeting with the rest of the + project members, or a person who owns a large house may want to + schedule a big party with his friends. The attendees will then + want to reply with messages such as, “I will + attend”, or “I will attend only if the proposed time + is changed”. + </para> + + <para> The &Evolution; groupware suite provides a framework for - developing calendaring applications.
