CARDAMOM is an open source CORBA middleware developed through collaboration between AMS and THALES to support distributed applications. It uses CORBA component model and provides services like events, data distribution, and fault tolerance. Its reference platforms are C++ using TAO Linux and Java using JacORB. The first project to use CARDAMOM is the Franco-Italian European Flight Data Processor.

3. Introduction
Collaboration agreement:
CARDAMOM is the concrete result of AMS and THALES
Collaboration agreement for the development of CORBA 3
compliant middleware.
Open source:
In order to ensure the large-scale dissemination and usage of
CARDAMOM and of the CORBA 3 standard AMS and
THALES have decided to distribute CARDAMOM as an open
source.
eFDP/fi middleware:

16. Principles - Why OMG's CORBA
Only middleware standard that
is non-proprietary
supports actually heterogeneity
platform
languages
is suitable to integrate smoothly legacy
CORBA is evolving towards more 'technical' features
CORBA-RT
Fault Tolerant CORBA
...
Not only plain synchronous method call (C/S)
Date and references31/03/03
supports asynchronism (events)
supports deferred synchronism (AMI)
supports data distribution (DDS)
