OMG Issues RFP for IDL of C++
Language Mapping Spec
September 28, 2020
technology standards organization Object Management Group has issued request for
proposal (RFP) an Interface Definition Language v4 (IDL4) to C++ Language
Mapping specification. The enhanced IDL4 to C++ Language Mapping specification
will provide Data Distribution Service (DDS™) and CORBA users and vendors with
an interoperable API for the C++ programming language, enabling the deployment
of new, vendor-neutral applications in a variety of industries.
OMG IDL is an excellent tool to model information and interfaces, and plays an
important role in well-known technologies, such as DDS and CORBA. The latest
version of the OMG IDL has been published as the ISO standard ISO/IEC
In the last few years, OMG has enhanced IDL, incorporating new syntax and a
flexible structure to support a whole new array of use cases. This evolution in
IDL requires updated language mappings so users of technologies like DDS and
CORBA, which use IDL to model information and interfaces, can benefit from the
new features when using general-purpose programming languages like C++, Java, or
The RFP solicits an updated IDL to C++ Language Mapping specification for the
most recent version of OMG IDL. The new standard mappings will be the latest
addition to a new generation of language mappings that the OMG has successfully
adopted for Java and C#.
existing IDL to C++ language mappings are currently being exercised by thousands
of DDS- and CORBA-based systems. As new systems adopt OMG IDL, it is important
to keep our standard mappings current so new and existing systems can benefit
from the new additions to the language," said RFP author Fernando Garcia Aranda,
Principal Software Engineer at Real-Time Innovations (RTI). "With this RFP, we
define an updated set of IDL to C++ mappings that make use of the new features
of the most recent versions of the OMG IDL to the fullest extent."
Both members and non-members of OMG may show their interest in participating in
the IDL4 to C++ Language Mapping RFP by submitting a Letter of Intent by
December 24, 2020. To submit individually or as part of a submission team,
companies must become members of OMG by the initial submission deadline of
February 22, 2021.
