BUT...

OSGi is hard?

OSGi enRoute“OSGi as it should be”

● Programming model using DS

● A repository of base APIs and implementation bundles

● Bndtools-based toolchain

● Latest OSGi R6 features

● New and useful extra services (i.e. configurer, scheduler, DTO conversion, REST, JSONRPC, Server Sent Events, …)

● Remote Launcher

THE UGLY

● OSGi-agnostic libraries ...

… that try to solve address similar problems as OSGi

22

THE BAD

● No open source implementations available for all specifications (i.e. DAL, EnOcean, ...)

● No standard interfaces / data format for representing things

● A lot of wrong use of OSGi

23

THE GOOD

● enRoute

● IoT Expert Group● Async event streams● Device abstraction layer● IoT Protocols

● OSGi is perfectly suited for IoT● Runs both on embedded as server● Modular device abstraction● Transparent remote services
