Hello Luigi, 1. to add custom enhancements to the content you can just add triples to the content's metadata graph (accessible in the enhancement engine).
2. if you really want a reference to the EntityHub, indeed you can use the OSGi API (through a BundleContent from your Activator). http://www.osgi.org/javadoc/r4v43/core/org/osgi/framework/BundleContext.html#getServiceReference%28java.lang.Class%29 Carpe diem Gabriel On Thu, Jan 10, 2013 at 4:18 PM, Luigi Selmi <[email protected]> wrote: > Hi Rafa, > thanks for your quick response.
