Abstract: A reproduction support apparatus supports reproduction of an OS is to be reproduced by a reproducing apparatus, and includes a processor configured to input a first identification data group that includes identification data identifying files of a file group constituting the OS to be reproduced; and a storage device storing a second identification data group that includes identification data identifying files of a file group constituting OSs of an OS group including the OS to be reproduced and the files of the file group constituting the OSs of the OS group. The processor is further configured to retrieve from the second identification data group, identification data matching the first identification data group; extract from the file group stored in the storage device, a file identified by the retrieved identification data; and transmit to the reproducing apparatus, information concerning files among the extracted files, for reproducing the OS to be reproduced.

Abstract: A computer program that provides users with an easy-to-understand overall view of relationships between objects. A data loader reads relationship information out of an object descriptor database and loads view-related object descriptors into a working memory, where the relationship information describes relationships between objects. A data sorter sorts the view-related object descriptors in the working memory into groups, based on their absorption, dependence, and exclusion relationships described in the relationship information. This sorting process yields a hierarchy of view-related object descriptors according to their absorption relationships. A hierarchy view data builder retrieves view-related object descriptors, along with link descriptors, from the working memory according to a structure tree that represents inter-object relationships. The hierarchy view data builder saves the retrieved view-related object descriptors in a tree hierarchy database.
