Method and apparatus for object traversing suitable for structured memory formed by linked objects

摘要

An object traversing scheme in which the traverse procedure and the traverse rights can be specified flexibly. In this scheme, the object is stored with an assignment of a traverse right for each sub-object indicating who is allowed to traverse each sub-object; at least one traverse IDs for identifying a user making a request to make an access to the object are specified; the sub-objects to be traversed at a time of traversing the object in response to the request from the user identified by the traverse IDs are selected according to the traverse right assigned to the user identified by the traverse IDs in the object; and the selected sub-objects are outputted as a result of the access to the object. The traverse IDs for identifying the user can be changed according to the traverse rights of the sub-objects and the selection of the sub-objects. This scheme can be utilized very beneficially in conjunction with an electronic mail tool. IMAGE
