Abstract

Systems and methods for managing digital assets in a distributed computing environment are described. Meta-data for the digital assets is stored separately from the digital assets. Meta-data for some of the digital assets is copied and stored at a central location. Meta-data for the digital assets is generated by clients of the system.

Claims

1. A method for tracking a number of copies of a digital asset in a distributed computing environment, the distributed computing environment having a central computing device that stores meta-data for at least one digital asset, and the distributed computing environment having one or more client devices that locally store digital assets and meta-data associated with the digital assets, the method comprising:

(a) receiving at a client device within a distributed computing environment, an instruction to copy an original digital asset, the original digital asset associated with an original meta-data entry;

(b) determining, responsive to receiving the copy instruction, the client device created a copy of the original digital asset;

(c) generating, by the client device in response to the determination that the digital asset copy was created, an additional meta-data entry indicating the copy of the original digital asset was created by the client device;

(d) adding the additional meta-data entry to the original meta-data entry to update the original meta-data entry associated with the original digital asset; and

(e) associating the original meta-data entry with the original digital asset copy;

wherein the original digital asset resides in the client device;

wherein determining that the client device created a copy of the original digital asset includes;

monitoring a series of file system input/output (I/O) operations occurring in the client device, and

detecting, among the series of file system I/O operations, a particular file system I/O operation which creates the copy of the original digital asset; and

wherein generating the additional meta-data entry indicating that the copy of the original digital asset was created by the client device includes;

creating the additional meta-data entry in response to detection of the particular file system I/O operation which created the copy of the original digital asset, the original meta-data entry and the additional meta-data entry concurrently residing on the client device, the original meta-data entry being associated with the original digital asset, and the additional meta-data entry being associated with the copy of the original digital asset;
