1. A method for providing configurable workflow for editing multimedia content and messaging events therein, the method comprising the steps of: (a) providing a system including at least one remote media asset node (MAN) including MAN server computer(s) associated with at least one client for editing multimedia content (MMC), the at least one remote MAN constructed and configured in electronic communication over a network to a global media hub (GMH) having GMH server computer(s) having a processor, a memory, and software operable thereon to control the processes that act on the MMC at the MANs, the GMH operable for storing the metadata associated with the MMC, and the MANs operable for storing the MMC; and a configurable workflow editor module having a messaging events function for notifying the user of the occurrence of user-predetermined at least one trigger event(s) within workflows through the system; (b) the MAN and GMH receiving workflow request inputs from a client user interface (UI) for directing workflow acting on the MMC, the workflow control being managed at the GMH; (c) the configurable workflow editor module receiving inputs from the client UI, the inputs including the user-predetermined at least one trigger event; (d) the system operating to execute a workflow including the user-predetermined at least one trigger event; and (e) the configurable workflow editor module automatically detecting the existence of the user-predetermined at least one trigger event and automatically generating a notification thereof for transmission to the client over the network.
