Fuchsia can materialize an outcast service (not visible in the OSGi platform) into the OSGi platform. Natively fuchsia can materialize:

All those are already built-in features, the materialization of an external service into OSGi platform, this processor is called: Importer.

The second type of processor is called Exporter, this type enables us to turn an OSGi service instance into a service that can be access outside of OSGi, exposed as a web service for instance. The built-in exporters are:

Of course those processors (importers or exporters) are available without needing to code a single line.

Albeit, Fuchsia has built-in processors, we are aware that most of applications use their own protocol or adopt their protocol specific device, knowing that Fuchsia was build to be extensible, thus implementing and deploying a customized processor is quite straight forward.
