Abstract

Systems and methods for synchronizing metadata with alterations to a PDF print job. One embodiment includes a system that includes a print server with an interface and memory. The interface receives a Portable Document Format (PDF) print job associated with a metadata file that defines contextual information for the PDF print job, and the memory stores an action list that defines a sequence of steps for modifying the PDF print job. The print server also includes a job controller that, for the sequence, iteratively detects a step that performs a change to printable content in the PDF print job, identifies a parameter field in the metadata file that relates to the printable content, and modifies the parameter field in the metadata file based on the change to the printable content in the PDF print job.

First claim

What is claimed is:

1. A system comprising:
a print server comprising:
an interface configured to receive a Portable Document Format (PDF) print job associated with a metadata file that defines contextual information for the PDF print job;
memory configured to store an action list that defines a sequence of steps for modifying the PDF print job; and
a job controller configured to initiate execution of the action list, to perform a step in the action list that causes a location shift of printable content in the PDF print job, to identify a parameter field in the metadata file that relates to the printable content affected by the location shift, and to automatically modify the parameter field in the metadata file based on the location shift to synchronize the metadata file with the PDF print job.

2. The system of claim 1 wherein:
the job controller is configured to modify the parameter field in the metadata file before execution of a subsequent step in the action list.

3. The system of claim 1 wherein:
the job controller is configured to modify the parameter field in the metadata file in response to execution of the step to apply the location shift to the printable content in the PDF print job.

4. The system of claim 1 wherein:
the job controller is configured to identify the parameter field by analyzing the metadata file for text that matches an instruction in the step.

5. The system of claim 1 wherein:
at least one step in the action list causes the location shift of the printable content by deleting content from the PDF print job.

6. The system of claim 1 wherein:
at least one step in the action list causes the location shift of the printable content by adding additional content to the PDF print job.

7. The system of claim 1 wherein:
the metadata file is a Job Definition Format (JDF) file that includes finishing instructions for pages of the PDF print job.

8. A method comprising:
receiving a Portable Document Format (PDF) print job associated with a metadata file that defines contextual information for the PDF print job;
storing an action list that defines a sequence of steps for modifying the PDF print job;
initiating execution of the action list;
performing a step in the action list that causes a location shift of printable content in the PDF print job;
identifying a parameter field in the metadata file that relates to the printable content affected by the location shift; and
automatically modifying the parameter field in the metadata file based on the location shift to synchronize the metadata file with the PDF print job.

9. The method of claim 8 further comprising:
modifying the parameter field in the metadata file before execution of a subsequent step in the action list.

10. The method of claim 8 further comprising:
modifying the parameter field in the metadata file in response to execution of the step to apply the location shift to the printable content in the PDF print job.

11. The method of claim 8 further comprising:
identifying the parameter field by analyzing the metadata file for text that matches an instruction in the step.

12. The method of claim 8 wherein:
at least one step in the action list causes the location shift of the printable content by deleting content from the PDF print job.

13. The method of claim 8 wherein:
at least one step in the action list causes the location shift of the printable content by adding additional content to the PDF print job.

14. A non-transitory computer readable medium embodying programmed instructions which, when executed by a processor, are operable for performing a method comprising:
receiving a Portable Document Format (PDF) print job associated with a metadata file that defines contextual information for the PDF print job;
storing an action list that defines a sequence of steps for modifying the PDF print job;
initiating execution of the action list;
performing a step in the action list that causes a location shift of printable content in the PDF print job;
identifying a parameter field in the metadata file that relates to the printable content affected by the location shift; and
automatically modifying the parameter field in the metadata file based on the location shift to synchronize the metadata file with the PDF print job.

15. The medium of claim 14 , wherein the method further comprises:
modifying the parameter field in the metadata file before execution of a subsequent step in the action list.

16. The medium of claim 14 , wherein the method further comprises:
modifying the parameter field in the metadata file in response to execution of the step to apply the location shift to the printable content in the PDF print job.

17. The medium of claim 14 , wherein the method further comprises:
identifying the parameter field by analyzing the metadata file for text that matches an instruction in the step.

18. The medium of claim 14 , wherein:
at least one step in the action list causes the location shift of the printable content by deleting content to the PDF print job.

19. The medium of claim 14 , wherein:
at least one step in the action list causes the location shift of the printable content by adding additional content to the PDF print job.

20. The medium of claim 14 , wherein:
the metadata file is a Job Definition Format (JDF) file that includes finishing instructions for pages of the PDF print job.
