1. A method, performed on a server computer, for generating a database of metadata that describes data objects, the method comprising:

  • interfacing with a file system associated with data stored on a storage device,wherein the file system provides access to data objects and metadata included within the data stored on the storage device, andwherein the file system is located on a client computer, external to, but communicatively coupled to, the server computer;

    wherein the interfacing includes;

    requesting metadata related to the data objects;

    receiving the requested metadata; and

    storing the received metadata within the database of metadata; and

    populating one or more data structures, wherein populating one or more data structures includes—

    registering, on the client computer, to receive change notifications from a change notification service;

    receiving a change notification from the change notification service of the client computer,wherein the change notification includes information regarding an interaction with a data object; and

    updating the one or more data structures to include information provided by the received change notification,wherein populating the one or more data structures occurs during substantially the same time as interfacing with the file system located on the client computer.
