Description of Document

The Message Abstraction layer (MAL) provides the basic toolkit of operations and messages that all MO services use to build their service specifications. It provides a standard abstract service to the higher MO services so that they can concentrate on the service specifics and remain transport and encoding agnostic. It provides a service model, a messaging infrastructure and a behaviour model that supports the definition of abstract MO services that are mapped to a specific programming language and a specific messaging technology at a later date in other books. By providing this abstract layer it allows the physical program representation and on the wire representation to be separated and therefore supports interoperability between components without requiring a fixed implementation language.
