Methods, systems, and computer program products for abstracting processing layers within a messaging infrastructure so that changes or enhancements can be made to the infrastructure while retaining existing functionality. Message transport implementations are abstracted within a message layer, allowing other layers within the infrastructure to interact with messages in a more structured fashion, largely independent of message transport. Transport examples include named pipes, Transmission Control Protocol (TCP), HyperText Transfer Protocol (HTTP), Simple Mail Transfer Protocol (SMTP), etc. A channel layer above the message layer abstracts message exchange implementations, allowing other layers within the infrastructure to send and receive messages in a more structured fashion, largely independent of the message exchange semantics of a specific implementation. Message exchange examples include datagrams, dialogs, monologs, queues, and the like. Above the channel layer and message layer, a service layer abstracts the binding implementations that bind message exchange implementations to user code implementations.

A “minimalized” key has the smallest length, overall volume and weight commensurate with the ability to operate a lock in the same manner as a corresponding conventional key. It is easily formed from a conventional key blank, preferably after unique edge profiling to suit the lock, by eliminating the head portion and providing an aperture in the remaining body portion for attachment of means that facilitate application of a torque to turn it to operate the lock. Minimalized key blanks are also easily and inexpensively made from strip stock of rectangular cross-section of appropriate dimensions by forming longitudinal grooves and an aperture in selected lengths thereof, and the minimalized key blanks so formed are then individually profiled to make minimalized keys to fit specific locks. They may also be color-coded to make them visibly distinguishable from one another. Because of their small size, minimalized keys, individually or attached to others, may be conveniently and safely carried in open casings or discreetly on the user's person.
