5. A distributed system operating in a landscape of computer systems providing message-based services defined in a service registry, the system comprising: at least one processor operable to execute computer readable instructions embodied on tangible media; a graphical user interface embodied by computer readable instructions executable by the at least one processor, embedded on non-transitory tangible media, for providing, from a resource data management system to a consumer system, a response to a query providing details for a single work center, where work centers are used in order processing to specify scheduling, capacity planning, and costing data associated with a business operation, using a request; a first memory storing a user interface controller for processing the request when executed by the at least one processor and involving a message including a message package derived from a common business object model, where the common business object model includes business objects having relationships that enable derivation of message-based service interfaces and message packages, the message package hierarchically organized as: a work center enterprise resource processing (ERP) by identifier (ID) response message entity; and a work center package and a log package, where the work center package includes a work center entity, where the work center entity includes an ID, a plant ID, a type code, a type name, a usage code, a usage name, and where the log package includes a log entity, where the log package stores information associated with the response; and a second memory, remote from the graphical user interface, storing a plurality of message-based service interfaces derived from the common business object model to provide consistent semantics with messages derived from the common business object model, where one of the message-based service interfaces is operable to process the message via the service interface when executed by the at least one processor, where processing the message includes unpacking the first message package based on the common business object model.
6. The distributed system of claim 5 , wherein the first memory is remote from the graphical user interface.
