At Object World in San Francisco this week, the seven vendors involved in developing the interoperability element of the CORBA 2 version of the Common Object Request Broker Archiitecture are expected to announce they will present a joint submission to the Object Management Group by its September 21 deadline. It will be at least partly based on the framework put forward by ICL Plc, which encompasses both common protocol and gateway approaches. The submitters agreed on this course of action at the last Object Group technical meeting in Pittsburgh on June 28 and 29. CORBA 2 is also likely to include standards for initialisation and specifications on how to add new definitions to the interface repository, which was outlined in CORBA 1.1. Both specifications should be finalised by the next Object Group meeting, to be held in Dublin, Ireland at the end of August.
