New CORBA 3.0 and CCM 3.0 specs

  Hello,

 I think it would be worth the place to announce new CORBA 3.0 and CCM
 3.0 specifications in 'Development' section of LWN. Unfortunately I
 don't know who is responsible for this section and so I'm sending
 this email directly to you in the hope that it'll find the right way.

 In case of any problem with this text, please contact me.

 Thanks,

 Karel



 CORBA 3.0 brings core changes to the CORBA which are required by new
 CORBA Component Model (CCM). From this point of view we can compare
 this specification with CORBA 2.0 specification which brought new
 GIOP/IIOP protocols which allow CORBA vendors products to
 interoperate on the wire. This was in 1995 and from this time whole
 CORBA ride out long way. Now CORBA 3.0 allows CORBA application
 developers to use component framework which from design point of view
 doesn't have competition in the market. There is nothing except CCM
 which brings ability to write/deploy/use components in language,
 operating systems and vendors independent way.

 CORBA 3.0 specification contains a lot of core changes, but the most
 visible are these required by CORBA Component Model. CCM as a whole
 is separated specification and specifies these main building blocks:

 - Component Model
 - OMG CIDL Syntax and Semantics
 - CCM Implementation framework
 - The Container Programming Model
 - Integration with Enterprise JavaBeans
 - Packaging and Deployment

 The CCM specification defines two compliant levels: basic and
 extended. The basic level is very similar to Enterprise JavaBeans
 from functionality point of view, but note that such components don't
 need to be implemented in Java, but also in other programming
 languages. The extended model provides all features and power of
 whole CORBA Component Framework. By using it the developers will be
 able to define all necessary interfaces, composition and persistent
 types using two declarative languages: Extended CORBA Interface
 Definition Language (IDL) and newly introduced Component
 Implementation Definition Language (CIDL). The goal is to write as
 much as possible in these languages and let IDL/CIDL compilers do the
 whole job except implementation of so called business logic, or
 business operations, which is duty of application developer and which
 has to be done in certain programming language.

 The first draft of CCM appears on the net in autumn 1999 and so it
 was really a long way to the final specification, but I hope it was
 worth the time.

 CORBA, IDL, CIDL, CCM are trademarks of Object Management Group (OMG)
 - software consortium which writes CORBA and many other specifications.
