#### 3.1.1 CORBA

CORBA is the OMG specification of a Distributed Object Computing (DOC) distribution model ([OMG04]). It is now a well-known and well-established specification, used in a wide range of industrial applications.

PolyORB provides a CORBA-compatible implementation based on a mapping of the IDL language version 1.2 described in [OMG01] and CORBA core specifications. PolyORB also provides an implementation of various additional specifications described by the OMG, including `COS Services: COS Naming, Notification, Event, Time`, and additional specifications: `RT-CORBA`, `PortableInterceptors`, `DynamicAny`.
