Abstract

Techniques for universal content traceability are presented. A piece of content is tagged with one or more content identifiers and with a unique instance identifier. The content also is tagged with content and instance-level metadata. The tagged information is maintained with the document and separately from the document in a centralized or distributed database system or table. As operations are performed on the content, the tagged information may be updated as necessary. The content can then use the tagged information in connection with the database to trace its origins and history during its lifecycle.

Claims

1. A method implemented in a non-transitory machine-readable storage medium and processed by one or more processors configured to perform the method, comprising:

identifying a piece of content;

assigning one or more content identifiers to the piece of content;

generating a unique instance identifier for the piece of content, the unique instance identifier unique to a particular copy of the piece of content and the one or more content identifiers are assigned to all copies of the piece of content, the unique instance identifier constructed based on a pathname for the particular copy of the piece of content and the pathname including an inode for the particular copy of the piece of content;

providing content metadata and instance metadata to the piece of content; and

recording the one or more content identifiers, the instance identifier, the content metadata, and the instance metadata in a database for subsequent traceability of the piece of content, wherein a total number of backlinks for any given piece of content is used for ranking that given piece of content, and when an imported different piece of content from an external system is detected performing a search and identifying a percentage of content matches for search results from the search as ancestors for the different piece of content, each ancestor identified as an unconfirmed ancestor to the different piece of content.

2. The method of claim 1, wherein identifying further includes detecting an event indicating that the piece of content is being one of:

created from scratch, copied, imported, modified, and cut and pasted.

3. The method of claim 1, wherein assigning further includes acquiring the one or more content identifiers based on one or more of:

another piece of content that this piece of content is derived from, key terms identified in the piece of content that are mapped to the one or more content identifiers, and user-supplied content categories for the piece of content.

4. The method of claim 1, wherein assigning further includes providing a uniform resource identifier (URI) link with the one or more content identifiers to the content metadata that when activated generates a collection of content having some or all of the one or more content identifiers.

5. The method of claim 1, wherein generating further includes generating the instance identifier as a Uniform Resource Identifier (URI) link using a unique pathname to a processing environment and a file having the piece of content.

6. The method of claim 1, wherein generating further includes updating a reference count for the instance identifier in the database.

7. The method of claim 1, wherein providing further includes including a hypertext back link within the instance metadata that links the piece of content to a parent piece of content from which the piece of content was derived.

8. The method of claim 1, wherein providing further includes providing with the content metadata:

copyright information, author identification, creation date and time for the piece of content, and mutability flags indicating whether the piece of content can be altered and/or copied.

9. The method of claim 1, wherein providing further includes providing with the instance metadata:

owner identification, access rights, byte size for the piece of content, and word counts for the piece of content.

10. The method of claim 1 further comprising, using extended and unused attribute fields maintained by an operating system managing the piece of content to retain the content metadata and the instance metadata with the piece of content.

11. A method implemented in a non-transitory machine-readable storage medium and processed by one or more processors configured to perform the method, comprising:

presenting a content traceability interface to a user;

receiving, via the interface and from the user, a file having a piece of content;

resolving one or more content identifiers and a unique instance identifier for the piece of content having a particular inode, and wherein resolving further includes identifying when the file is received as an imported file from an external system and performing a search identifying a percentage of file matches for search results from the search as ancestors for the imported file, each ancestor identified as an unconfirmed ancestor to the imported file;

accessing a database using the one or more content identifiers and the instance identifier; and

providing, via the interface, one or more tracing maps for the piece of content to the user and automatically creating a versioning system for the piece of content based on the unique instance identifier, and wherein each piece of content is ranked based at least in part on a total number of backlinks associated with that piece of content.

12. The method of claim 11 further comprising, enabling the one or more tracing maps to be interactive and permitting nodes of the map to be activated by the user to jump directly to a different piece of content.

13. The method of claim 11 further comprising, permitting the user to execute searches against all or selective parts of the one or more tracing maps.

14. The method of claim 11 further comprising, generating a textual timeline with descriptive information for the one or more tracing maps as a genealogy report for the piece of content.

15. The method of claim 11 further comprising, providing rankings with each node of the one or more tracing maps, each ranking identifying a percentage of relevance a particular node has to the piece of content.

16. The method of claim 11, wherein presenting further includes presenting the interface as a world-wide web (WWW) accessible web page from an Internet portal.

17. The method of claim 11, wherein resolving further includes searching the database based on extracted keywords from the piece of content to find the one or more content identifiers when metadata associated with the piece of content supplied in the interface lack the one or more content identifiers.

18. A multi-processor implemented system, comprising:

a server machine having multiple processors; and

the server machine configured with and to execute a server agent and to interact with one or more client agents executing on one or more client machines;

the server agent configured to interact with each client agent to supply each piece of content being manipulated on a particular client machine with one or more content identifiers, a unique instance identifier, content metadata, and instance metadata, and the server agent further configured to maintain a database to link the content identifiers and instance identifiers to other pieces of content managed in the database to create traceability for content using inodes of the identifiers and pathnames for the identifiers, the instance identifiers used for automatically creating a versioning system for each piece of content, each piece of content is ranked based at least in part on a total number of backlinks associated with that piece of content, and wherein the server agent further configured to search an external system when a particular piece of content is identified as an imported piece of content to identify a percentage of content matches for search results from the search as ancestors for the imported piece of content, each ancestor identified as an unconfirmed ancestor to the imported piece of content.

19. The system of claim 18, wherein the server agent is further configured to generate tracing maps from the database for a given piece of content.

20. The system of claim 19, wherein the server agent is further configured to interact with an interface presented by the server to a user to receive the given piece of content and to present the tracing maps within the interface.
