omniORB : Free CORBA ORB
omniORB is a robust high performance CORBA ORB for C++ and Python. It is freely available under the terms of the GNU Lesser General Public License (for the libraries), and GNU General Public License (for the tools). omniORB is largely CORBA 2.6 compliant.
omniORB is one of only three ORBs to have been awarded the Open Group's Open Brand for CORBA. This means that omniORB has been tested and certified CORBA compliant, to version 2.1 of the CORBA specification. You can find out more about the branding program at the Open Group.
