D-Bus 1.0 offers desktop Linux app interoperability
D-Bus 1.0 ("Blue Bird"), the Freedesktop.org inter-process messaging system has just been released. A collaborative effort between industry and open source developers, D-Bus was created to allow arbitrary applications to easily communicate with each other and exchange data.
D-Bus 1.0 seems at the same time to be both such a simple and such an esoteric thing. On the one hand, it's simply another IPC (interprocess communication) system. On the other, it may prove as important for Linux desktop developers as ActiveX has been for Windows programmers.
The importance of this first release of D-Bus from the FreeDesktop.org project is that D-Bus will go a long way toward improving interoperability between Linux desktop applications. D-Bus has already been adopted by the Portland Project for its forthcoming DAPI (Desktop Application Programming Interface).
