1. A method for implementing feed-based promotion of objects, the method comprising: associating an object maintained in a service registry of a governance domain with a governance lifecycle, where the governance lifecycle transitions through states; associating the object with at least one feed maintained by the governance domain; monitoring the object for a lifecycle state transition; determining whether a detected lifecycle state transition is relevant to a corresponding feed subscribed-to by a non-governance domain; publishing an alert on the corresponding feed if the monitored object transitions from one lifecycle state to another lifecycle state and the detected lifecycle state transition is relevant to the corresponding feed; and exposing an application programming interface through which a production service registry of a non-governance domain pulls a copy of the monitored object in response to the alert.
