Method and apparatus for supporting cooperative works via computer network

摘要

A scheme for supporting cooperative works capable of reproducing the contents of the past works from the recorded history of the cooperative works accurately, such that the cooperative works can be carried out efficiently and smoothly. In this scheme, the inputs made by each user during the cooperative works are stored in correspondence to input target data indicating input target applications of the inputs as a record of the cooperative works. Then, afterwards, the input target applications indicated by the input target data are re-executed according to the stored inputs to reproduce results of the cooperative works resulting from the inputs which can be presented to each user.
