Systems and methods for the organization of hierarchical events are disclosed. A parent event in a first calendar application workspace classifies a hierarchy of events. A child event child event corresponds to a hierarchy of events. Identification of the parent event and a new child event results in the display of the new child event in a second calendar application workspace, the new child event being a scheduled event in the hierarchy of events that does not indicate a calendaring conflict with the parent event. A collaborative organization environment for discussion concerning the new child event may be provided.
