Abstract: A Web service synchronization protocol is provided that sets forth the metadata and messaging by which endpoints roam, share and synchronize common information with one another in a multi-master networked computing ecosystem. A general SOAP-based protocol is defined for synchronizing data between two endpoints where one or more of the endpoints supports a Web service. Defining messaging for knowledge-based transfers using XML Web services, the protocol allows devices, services and applications to synchronize through firewalls, allows for flexibility by allowing any common set or subset of information across endpoints and allows for extensibility by not prescribing the schema of the actual data being synchronized at the endpoints.

Abstract: A nacelle is configured to be coupled to an underside of a wing and forms a clearance space between the nacelle and a leading edge slat of the wing. A portion of an outlet cowling moves longitudinally aft when a reverse thrust configuration is activated and the leading edge slat is deployed toward the nacelle. The outlet cowling also includes another portion located adjacent to the leading edge slat that does not move when the reverse thrust configuration is activated and thus maintains its clearance space from the leading edge slat.
