Claim:
A structured document transforming apparatus that manages document information transfers between a server and at least one of a plurality of clients, the structured document transforming apparatus performing bidirectional transformation between a first structured document having a first server-compatible format and a second structured document having a second format, the second format being a client-compatible format and being one of a plurality of formats employed by the plurality of clients, wherein the first structured document and the second structured document each includes elements, comprising: means for receiving a request from the at least one of the plurality of clients; means for storing a transformation rule having primitive rules, each of which are applicable to a respective one of the elements specified in units of paths within the first structured document in response to the request, wherein the units of paths are path names designating specific areas in the first structured document; means for detecting an important element within the elements of the first structured document in response to the request, wherein the important element includes a semantic combination; means for performing a forward transformation that transforms the first structured document into the second structured document in accordance with the transformation rule; means for controlling the forward transformation to prevent the removal of the important element during the forward transformation; means for creating a transformation record wherein the primitive rules that were applied and the paths that were transformed in the forward transformation are recorded; means for transferring the second structured document to the at least one client for editing; and means for performing a backward transformation that transforms the edited second structured document into the first structured document with referral to the transformation record, the transformation rule, and the first structured document.
