The Object Management Group is inching its Common Object Request Broker Architecture along, and has now issued requests for documentation on extensions to the Object Broker and data on establishing interface definition language mapping for C++ in the broker mechanism. Extensions to the Object Broker for which the Framingham, Massachusetts keeper of the object-oriented flame is seeking information include repository application programming interfaces, additional language bindings or object adaptors, and extensions and additions to core Object Request Broker functionality in the areas of support for transactions and concurrency generation. The goal of standardising on an interface definition language mapping for C++ is to support interoperability between applications that are written in different languages but include extensions that support the Object Group’s interface definition language.
