Universal content traceability

摘要

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.

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.
