1. A method for causing a physical modification to a machine-readable medium having encoded thereon data representative of a hierarchy, the method comprising:

  • making a Web page available for access by a user at a first client, the Web page including(i) locally-stored data representing the hierarchy and(ii) rules defining those modifications to a structure of the locally-stored data representing the hierarchy that any user is permitted to make to the data;

    receiving, from the user, instructions to modify the structure of the hierarchy in real-time;

    performing local rule enforcement at the first client by verifying that a proposed modification to the locally-stored data complies with the rules; and

    detecting at a server, in real-time, a modification to locally-stored data occurring at a second client;

    sending a call from the first client to the server to enforce rules involving multiple users based on detecting the modification to locally-stored data that occurred at the second client, the call being sent before the modified data has been saved to a master representation of the hierarchy on the server; and

    causing the physical modification of the machine-readable medium, the physical modification resulting in the master representation of the hierarchy.
