Patent number: 7228498Abstract: A method, apparatus, and computer program product for performing bidirectional transformation between a first structured document and a second structured document is disclosed. A transformation rule having primitive rules each of which is applicable to respective one of elements specified in units of paths within the first structured document is prepared. A forward transformation is performed, which transforms the first structured document into the second structured document in accordance with the transformation rule. At that time, a transformation record is created. The record contains which primitive rules were applied and which paths were transformed in the forward transformation. The transformed second structured document may be edited by an application-side. After that, a backward transformation is performed, which transforms the second structured document into the first structured document with referral to the transformation record, the transformation rule, and the first structured document.Type: GrantFiled: March 24, 2006Date of Patent: June 5, 2007Assignee: Kabushiki Kaisha ToshibaInventors: Osamu Torii, Tetsuro Kimura, Junichi Segawa

Publication number: 20070013701Abstract: According to an aspect of the present invention, in a virtual space unit area, a message is distributed among computers using a physical topology based on a physical network. This avoids delaying operations in a computer which are related to those in another computer on a virtual space and taking a roundabout route on the physical network for distribution. On the other hand, outside the virtual space unit area, a message is distributed among computers using a virtual topology based on a virtual space. Consequently, the computers forming the physical topology can be limited to those present in the virtual space unit area. It is thus possible to reduce the amount of communication required to measure physical network distances.Type: ApplicationFiled: June 14, 2005Publication date: January 18, 2007Inventors: Junichi Segawa, Hideki Yoshida, Tetsuro Kimura
