Patent ID: 8127306

Claim:
A method for processing a plurality of event subscription requests at a multi-functional peripheral (MFP), wherein the MFP executes a device facility manager (DFM) and a plurality of service applications that each provides at least one service, the method comprising: receiving, from a client application, at a service application of the plurality of service applications, a request to subscribe to an event, wherein: the request is an event subscription request; the service application includes (1) an event manager that (a) is a component of the service application and (b) implements an eventing specification and (2) one or more components, other than the event manager, that correspond to the at least one service provided by the service application; the service application executes as a single process and implements functionality of the event manager in addition to functionality of the one or more other components that correspond to the at least one service provided by the service application; the at least one service provided by the service application is one of printing, faxing, or scanning; wherein the event manager is configured to perform at least one of the following additional functions: retrieve a status corresponding to a particular event, update said status, unsubscribe the particular event, or renew the particular event; wherein the DFM (i) executes on the MFP separate from the plurality of service applications, (ii) processes device metadata requests from one or more client applications that seek one or more services provided by the MFP, and (iii) implements, for the plurality of service applications, a plurality of Web Services specifications, each of which is different than the eventing specification; wherein none of the plurality of service applications implements any of the plurality of Web Services specifications; the event manager maintaining identification information that identifies at least the event specified in the request; wherein the event manager maintaining identification information includes: the event manager sending, to a component of the one or more other components of the service application, first data, from the event subscription request, that is specific to the service application; the component of the service application processing said first data to generate second data; the component of the service application sending the second data to the event manager; the event manager including the second data in a subscribe response that is generated by the event manager; and the event manager sending the subscribe response to the client application; the event manager receiving, from a platform of the MFP, notification data that indicates that the event occurred; the event manager comparing the notification data with the identification information; based on the comparison, the event manager composing a notification message; and sending the notification message to one or more intended recipients.
