A method for the implementation of business to business event handling mechanisms for use in coarse grain components allowing communication of event information among providers and interested subscribers across a network. Provision of a flexible method for resolution of business event model dependencies allows a business component to define its own business event model independently and further may also allow changes to that model. This provision may be used to allow a client without an event handling server to place a dependency on another business component for the provision of event handling services. Further, using a web services architecture network implementation for communications, provides the capability of a business event handling system as a web service.
