Abstract
A method for controlling copyright permissions when assembling multiple copyrighted works into a compiled file. The copyright permission level of each file is analyzed, either based on the copyright permission information present in metadata associated with the file or based on the digital file format of the file which reflects the permission level. The compiled file is assigned a permission level which is the same as or more restrictive than all of the permission level of the files in the compilation, and is generated in a format that enforces the assigned permission level. A notification may be displayed to the user to notify the use of the permission level assigned to the compiled file.
Claims10
A method for generating a compiled file, comprising:
- receiving a plurality of digital files each representing a work, at least some of the files each having metadata associated with it which specifies a permission level for using the file or having a file format which is compatible with a permission level for using the file, wherein each permission level includes a print-permission parameter regarding whether or not to permit printing of the file;
- receiving a user instruction to produce a compiled file containing contents of the plurality of files;
- analyzing the permission level of each of the plurality of files based on the metadata associated with the file and/or the file format of the file, and comparing a plurality of permission levels of the plurality of files to determine a most restrictive permission level among the plurality of permission levels of the plurality of files contained in the compiled file, wherein the determined most restrictive permission level includes a print-permission parameter regarding whether or not to permit printing of the compiled file which is the most restrictive among the print-permission parameters of the plurality of permission levels of the plurality of files;
- when the print-permission parameter of the determined most restrictive permission level indicates that printing of the compiled file is not permitted;
- notifying the user of the most restrictive permission level which is to be assigned to the compiled file;
- after the notification, receiving a response from the user containing an instruction to continue with compilation;
- and
- after receiving the response from the user, generating the compiled file containing the contents of the plurality of files indicated in the user instruction, the compiled file having an assigned permission level which is the same as or more restrictive than the most restrictive permission level of the plurality of files determined by the comparison;
- and
- when the print-permission parameter of the determined most restrictive permission level indicate that printing of the compiled file are permitted, generating the compiled file containing the contents of the plurality of files indicated in the user instruction, the compiled file having an assigned permission level which is the same as or more restrictive than the most restrictive permission level of the plurality of files determined by the comparison, without notifying the user.

A computer program product comprising a computer usable non-transitory medium having a computer readable program code embedded therein for controlling a data processing apparatus, the computer readable program code configured to cause the data processing apparatus to execute a process for generating a compiled file, the process comprising:
- receiving a plurality of digital files each representing a work, at least some of the files each having metadata associated with it which specifies a permission level for using the file or having a file format which is compatible with a permission level for using the file, wherein each permission level includes a print-permission parameter regarding whether or not to permit printing of the file;
- receiving a user instruction to produce a compiled file containing contents of the plurality of files;
- analyzing the permission level of each of the plurality of files based on the metadata associated with the file and/or the file format of the file, and comparing a plurality of permission levels of the plurality of files to determine a most restrictive permission level among the plurality of permission levels of the plurality of files contained in the compiled file, wherein the determined most restrictive permission level includes a print-permission parameter regarding whether or not to permit printing of the compiled file which is the most restrictive among the print-permission parameters of the plurality of permission levels of the plurality of files;
- when the print-permission parameter of the determined most restrictive permission level indicates that printing of the compiled file is not permitted;
- notifying the user of the most restrictive permission level which is to be assigned to the compiled file;
- after the notification, receiving a response from the user containing an instruction to continue with compilation;
- and
- after receiving the response from the user, generating the compiled file containing the contents of the plurality of files indicated in the user instruction, the compiled file having an assigned permission level which is the same as or more restrictive than the most restrictive permission level of the plurality of files determined by the comparison;
- and
- when the print-permission parameter of the determined most restrictive permission level indicate that printing of the compiled file are permitted, generating the compiled file containing the contents of the plurality of files indicated in the user instruction, the compiled file having an assigned permission level which is the same as or more restrictive than the most restrictive permission level of the plurality of files determined by the comparison, without notifying the user.
