Abstract

System and methods are herein disclosed for reconciling image metadata in an image file between different metadata schemas, both in the utilization of said metadata by an application or device, as well as proactively reconciling conflicts when detected in said image file. Several embodiments are directed to logically reconciling conflicting metadata between two or more metadata components related to read or write operations of said metadata by applications or devices. Several other embodiments are directed to proactively finding conflicts in metadata components of a file and proactively reconciling them for present and future utilization of said file.

Claims

1. A method for reconciling, in a single image file, inconsistencies between at least two metadata schemas having a common overlapping metadata component, said method comprising:

comparing the overlapping metadata component from each metadata schema to determine if a conflict exists; and

if a conflict exists, selecting the metadata component from one metadata schema (the “

selected schema”

) for utilization.

2. The method of claim 1 wherein the selected metadata schema is the most expressive metadata schema from among the at least two metadata schemas.

3. The method of claim 2 wherein the most expressive metadata schema is predefined.

4. The method of claim 2 wherein the most expressive metadata schema is XMP.

5. The method of claim 1 wherein the selected metadata schema is the metadata schema with the most expressive metadata component from among the at least two metadata schemas.

6. The method of claim 1 further comprising, if a conflict exists, updating at least one other metadata schema that is not the selected schema with the metadata component from the selected schema.

7. The method of claim 1 further comprising, if a conflict exists, updating at least one other metadata schema that is not the selected schema by zeroing-out the metadata component of said metadata schema.

8. The method of claim 1 wherein elements of said method are embodied as a system comprising at least one subsystem for performing one or more elements of said method.

9. The method of claim 1 implemented by a hardware control device, said hardware control device comprising means for implementing each element of said method.

10. A computer-readable medium comprising computer-readable instructions for reconciling, in a single image file, inconsistencies between at least two metadata schemas having a common overlapping metadata component, said computer-readable instructions comprising instructions for:

comparing the overlapping metadata component from each metadata schema to determine if a conflict exists; and

if a conflict exists, selecting the metadata component from one metadata schema (the “

selected schema”

) for utilization.

11. The computer-readable medium of claim 10 further comprising instructions whereby the selected metadata schema is the most expressive metadata schema from among the at least two metadata schemas.

12. The computer-readable medium of claim 10 further comprising instructions whereby the selected metadata schema is the metadata schema with the most expressive metadata component from among the at least two metadata schemas.

13. A method for writing metadata to a single image file having at least two metadata schemas, said method comprising:

if said metadata can be adequately written to any of said at least two metadata schemas, then writing said metadata to all of said at least two metadata schemas capable of storing said metadata; and

if said metadata cannot be adequately written to any of said at least two metadata schemas, then adding a new metadata schema to said image file and writing said meta to said new metadata schema.

14. The method of claim 13 wherein said new metadata schema is the most expressive metadata schema that can be added to said image file.

15. The method of claim 14 wherein the most expressive metadata schema is predefined.

16. The method of claim 14 wherein the most expressive metadata schema is XMP.

17. The method of claim 13 wherein elements of said method are embodied as a computer-readable instructions in a computer-readable medium.

18. The method of claim 13 wherein elements of said method are embodied as a system comprising at least one subsystem for performing one or more elements of said method.

19. The method of claim 13 implemented by a hardware control device, said hardware control device comprising means for implementing each element of said method.
