| 1. A method for maintaining a representation of a history of operations performed on document files in a data processing environment,
the method comprising:
sensing access events that involve accessing one or more digital assets at a user client computer device, the step of sensing
access events being carried out by a monitor process located within an operating system kernel of the user client computer
device;
in response to sensing an access event involving an operation on an existing document file, determining a relationship descriptor
that depends on the sensed access event;
in response to sensing an access event in which a new document file is created, comparing contents of the new document file
with contents of existing document files contained in a database to measure a percentage of similar content between the contents
of the new document file and the contents of the existing document files contained in the database to determine a relationship
descriptor for the new document file, the relationship descriptor quantifying a degree by which at least one of the existing
document files was modified to create the new document file; and
creating an entry in the representation that contains the relationship descriptor.
