CORBA Components

Specification

Î

Defined by the Object Management Group (OMG)

Î

A set of concepts, notations, and APIs to

¾Design ¾Implement ¾Package ¾Assemble ¾Deploy ¾Execute

distributed, heterogeneous, secure, transactional,

server-side scalable, CORBA component-based

applications

OpenCCM Goals

Î

Federate a world-wide community around CORBA

component-based middleware and applications

¾Users, developers, and contributors ¾Industrial and academic R&D

zTHALES, Cadena from Kansas University, …

Î

Provide the Open CORBA Components platform

¾Reference implementation ¾ORB product independent

¾Modular, extensible and adaptable for building CCM++

Î
