Abstract

Systems, methods, devices, and computer-readable media for managing duplicate media items. The system first analyzes a first file from a first source, wherein the first file is a duplicate of a second file. Next, the system deduplicates the first file and the second file to yield a deduplicated file. The system then selects metadata associated with at least one of the first file or the second file to be assigned as metadata for the deduplicated file, the metadata being selected based on a priority preference.

Claims

1. A method comprising:

analyzing a first file from a first source to determine that the first file is a duplicate of a second file from a second source;

deduplicating, via a processor, the first file and the second file to yield a deduplicated file; and

selecting metadata associated with at least one of the first file or the second file to be assigned as metadata for the deduplicated file, the metadata being selected based on a priority preference.

2. The method of claim 1, further comprising determining an identity of the first source, and wherein the priority preference is based on the identity of the first source.

3. The method of claim 2, wherein the priority preference is further based on a type of metadata.

4. The method of claim 1, further comprising storing, in a database, the metadata selected to be assigned as metadata for the deduplicated file, wherein the metadata is associated with the deduplicated file.

5. The method of claim 1, wherein the first file and the second file comprise media content and metadata.

6. The method of claim 1, further comprising overwriting existing metadata stored on a database with the metadata selected, wherein the existing metadata is associated with one of the first file or the second file.

7. The method of claim 1, wherein the priority preference comprises a matrix of rules that maps the first source and the second source to rules for ignoring or preserving files associated with the first source and the second source.

8. The method of claim 1, wherein the selected metadata overwrites a portion of existing metadata.

9. A method comprising:

receiving content at a device, the received content comprising a content item having content and at least a portion of metadata matching content and metadata associated with an existing content item stored at a content database, wherein the content database stores content items and respective metadata for each content item;

determining an identity of a source of the received content;

based on the identity of the source, determining a priority ordering of metadata associated with the content item and the existing content item;

deduplicating the content item and the existing content item based on the received content to yield a deduplicated content item, wherein the deduplicated content item is stored at the content database and associated with the respective metadata stored at the content database for the existing content item; and

based on the priority ordering of metadata, determining whether to overwrite any of the respective metadata associated with the deduplicated content item with any of the metadata associated with the content item.

10. The method of claim 9, wherein priorities assigned to metadata in the priority ordering of metadata vary based on a respective source of the metadata, and wherein portions of metadata associated with a given content item vary based on respective sources of the portions.

11. The method of claim 9, wherein deduplicating the content item and the existing content item, and determining whether to overwrite any of the respective metadata associated with the deduplicated content item with any of the metadata associated with the content item are further based on the identity of the source.

12. The method of claim 9, wherein at least one of determining a priority ordering of metadata or determining whether to overwrite any of the respective metadata associated with the deduplicated content item with any of the metadata associated with the content item is further based on a matrix of rules that maps a source to rules for ignoring or preserving metadata values received from the source that correspond to metadata fields in the content database.

13. A system comprising:

a processor; and

a computer-readable medium having stored thereon instructions which, when executed by the processor, cause the processor to perform operations comprising;

analyzing a first file from a first source to determine that the first file is a duplicate of a second file from a second source;

deduplicating the first file and the second file to yield a deduplicated file; and

selecting metadata associated with at least one of the first file or the second file to be assigned as metadata for the deduplicated file, the metadata being selected based on a priority preference.

14. The system of claim 13, wherein the computer-readable storage medium stores additional instructions which result in the operations further comprising determining an identity of the first source, and wherein the priority preference is based on the identity of the first source.

15. The system of claim 13, wherein the computer-readable storage medium stores additional instructions which result in the operations further comprising storing, in a database, the metadata selected to be assigned as metadata for the deduplicated file, wherein the metadata is associated with the deduplicated file.

16. The system of claim 13, wherein the priority preference comprises a matrix of rules that maps the first source and the second source to rules for ignoring or preserving files associated with the first source and the second source.

17. A non-transitory computer-readable storage medium having stored therein instructions which, when executed by a processor, cause the processor to perform operations comprising:

analyzing a first file from a first source to determine that the first file is a duplicate of a second file from a second source;

deduplicating the first file and the second file to yield a deduplicated file; and

selecting metadata associated with at least one of the first file or the second file to be assigned as metadata for the deduplicated file, the metadata being selected based on a priority preference.

18. The non-transitory computer-readable storage medium of claim 17, storing additional instructions which result in the operations further comprising determining an identity of the first source, and wherein the priority preference is based on the identity of the first source.

19. The non-transitory computer-readable storage medium of claim 17, storing additional instructions which result in the operations further comprising storing, in a database, the metadata selected to be assigned as metadata for the deduplicated file, wherein the metadata is associated with the deduplicated file.

20. The non-transitory computer-readable storage medium of claim 17, wherein the priority preference comprises a matrix of rules that maps the first source and the second source to rules for ignoring or preserving files associated with the first source and the second source.
