The Component-Integrated ACE ORB (CIAO) is a CORBA component model (CCM) implementation built on top of TAO.
CIAO is currently aiming to provide component-oriented paradigm to the distributed, real-time, embedded (DRE) system developers by abstracting DRE-critical systemic aspects, such as quality of service requirements, RT policies, as installable/configurable units supported by the component framework.
Promoting these DRE-critical aspects as first-class metadata disentangles code for controlling these non-function aspects from application logic and makes DRE system development more flexible.
CIAO also provides an implementation of the DDS4CCM standard which integrates DDS as publish-subscribe middleware into the component model.
By making benefit of the IDL to C++11 language mapping AXCIOMA is much easier to use as compared to CIAO.
