### 9. Glossary

CORBA

  Common Object Request Broker Architecture, standard introduced by the OMG for distributed components that can be used independently of platform, implementation and operating system. CORBA itself is only the standard which requires a corresponding implementation that fulfills the requirements of the standard. KDE uses the MICO implementation, which provides a C++ interface to CORBA services.

BOA

  Basic Object Adapter. Interface defined by the OMG, which offers fundamental operations for managing remote objects.

COS

  Common Object Services. Collection of standard services to simplify developing standard applications. Naming, Event and Lifecycle-services are a part of the COS collection.

DII

  Dynamic Invocation Interface, interface to execute dynamic invocations in opposition to static invocations (clent side)

Dynamic Invocation

  Creation and execution of a request, whose signature is probably first known at runtime in opposition to static invocation.

DSI

  Dynamic Skeleton Interface. Server side in opposition to a DII.

GIOP

  General-Inter-ORB-Protocol

IIOP

  Internet-Inter-ORB-Protocol

IMR

  Implementation Repository

IOR

  Interoperable Object Reference. The reference is specificated in the two parts GIOP and IIOP.

IDL

  Interface Definition Language. C++-Syntax similar programming language to describe object interfaces. The implementation translates IDL's to their target programming language.

Interface

  in CORBA, all exported methods and attributes of an object are called an interface, whereby these are defined in IDL. Elements which are not specified in the interface are not accessible by clients.

IOP

  Interoperability Profile

MICO

  free implementation of the CORBA standard. KDE's KOM/OpenParts technology is based on the MICO implementation.

OMA

  Object Management Architecture

OMG

  Object Management Group

ORB

  Object Request Broker, abstract name for the communication service between clients and remote objects.

POA

  Portable Object Adapter. The POA extends the features the BOA provides; introduced in the CORBA 2.2 standard.
