The contents of the OSGi Enterprise Specification. Many of the capabilities of the Enterprise
Specification are also included in the Compendium and Core Specifications. The first version
of the Compendium Specification was version 4.0, and the first version of the Enterprise
Specification was version 4.2.

Other specifications
OSG
i includes two other specifications, the Mobile Specification and the Residential
Specification. Like the Enterprise Specification, the Mobile Specification is a conve-
nient packaging of bits from the Compendium that are useful for mobile comput-
ing, along with some entirely new service definitions. The Mobile Specification on its
own isn't useful for enterprise computing, and we don't cover it in this topic. New in
OSG
i 4.3 is the Residential Specification, which is designed for devices like home ste-
reo systems, thermostats, and washing machines.
B.3
OSGi—future frontiers
Where next for
OSG
i? After it makes its mark in the embedded world, the mobile world,
and the enterprise, are there any industries left to conquer? Occasionally, discussions
about using
OSG
i as a gaming platform can be heard, but it's not clear yet that the prob-
lems of the gaming industry line up so well with the solutions offered by
OSG
i. The big-
ger challenge for
OSG
i in the future might be its relationship to core Java.
