Common Object Request Broker Architecture

(standard, 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.

Latest version: Corba 3.0.3 2004-03-12, as of 2007-09-04.

In addition to upgrades that make it easier to securely manage Orbix deployments in large production systems, users can address services via CORBAloc so that core Orbix services can be addressed with a URL.
