Title: Next generation epics interface to abstract data.

The set of externally visible properties associated with process variables in the Experimental Physics and Industrial Control System (EPICS) is predefined in the EPICS base distribution and is therefore not extensible by plug-compatible applications. We believe that this approach, while practical for early versions of the system with a smaller user base, is now severely limiting expansion of the high-level application tool set for EPICS. To eliminate existing barriers, we propose a new C++ based interface to abstract containerized data. This paper describes the new interface, its application to message passing in distributed systems, its application to direct communication between tightly coupled programs co-resident in an address space, and its paramount position in an emerging role for EPICS -- the integration of dissimilar systems.
