1. A computer-implemented method for role-based personalization of a collaborative space comprising: obtaining, using a computer hardware system, role-based information for an interacting user that has been defined by an underlying business process model in a workflow; and generating, in the computer hardware system, the collaborative space utilizing the role-based information, including: parsing the workflow to extract a role model; generating a collaborative space domain model from the role model; selecting a plurality of user interface components based upon the role model, wherein mapping rules are defined to transform role information aggregated in the role model to user interface components for incorporation in the collaborative space domain model, and wherein the mapping rules include user-specified mapping rules between a group of workflow tasks and existing user interface components where existing user interface components exist when the collaborative space is created, and suggested mapping rules obtained by segmenting the workflow based upon role-assignment or a control-flow structure where user interface components do not exist when the collaborative space is created; organizing the selected user interface components in the collaborative space; and rendering the collaborative space.
2. The method of claim 1 , wherein the generating the collaborative space domain model comprises selecting a plurality of tasks to be performed by the interacting user based upon the role model and incorporating the selected tasks in the collaborative space domain model.
