A method includes defining collaborative information spaces (CISs) on a corporate intranet using semantic definitions that reflect how people work together. A classification scheme allows network spaces (e.g., intranet spaces) to be defined, e.g., defining resources and/or information associated with tasks and people. The classification scheme may also be used to define standard collaborative entities that should be supported within an enterprise. The CIS(s) and/or collaborative entities may have associated privacy levels to control access to information and resources of the CIS. The classification scheme allows a user, or group of users, to define public and private information spaces. For example, a user may define public information on a web-page that defines the users skills and assigned tasks. The user may have another set of private information that is accessible only to other members of others having a common task.
