1. Common Object Model Component Object Model Common Object Request Broker Architecture programming> CORBA An Object Management Group specification which provides a standard messaging interface between distributed objects. The original CORBA specification 1. 1 has been revised through version 2 CORBA 2 with the latest specification being version 3 CORBA 3. In its most basic form CORBA consists of the Interface Definition Language IDL and the Dynamic Invocation Interface DII. The IDL definition is complied into a Stub client and Skeleton server component that communicate through an Object Request Broker ORB. When an ORB determines that a request is to a remote object, it may execute the request by communicating with the remote ORB. The Corba IDL can be mapped to a number of languages including C, C++, Java, COBOL, Smalltalk, Ada, Lisp, Python, and IDLscript. CORBA ORBs are widely available for a number of platforms. The OMG standard for inter-ORB communication is IIOP, this ensures that all CORBA 2 compliant ORBS are able to interoperate. See also COSS, Component Object Model, RMI.
