[news.eclipse.technology.riena] Re: R-OSGi

[Scott Lewis <slewis@xxxxxxxxxxxxx>]

FYI,

Jan Rellermeyer, the author of r-OSGi has joined the ECF team as a 
contributor, and is in the process of implementing the ECF remote 
services API with r-OSGI.  That is, he is using r-OSGi to implement the 
ECF remote services API: 
http://wiki.eclipse.org/index.php/ECF_API_Docs#Remote_Services_API

We've also finished an update to the ECF discovery API:
http://wiki.eclipse.org/index.php/ECF_API_Docs#Discovery_API

Jan has also committed his SLP implementation and an ECF discovery API 
implementation has been created out of it.

The purpose of the ECF discovery and remote services API is to provide a 
transport-independent access to remote OSGi services, with proxies, as 
well as asynch invocation, one-ways, and future style of remote invocation.

I hope the Riena team doesn't go to the trouble of creating a 
transport/communications independent discovery and/or remote services 
APIs...since it would be more efficient and community-friendly to use 
and/or build upon, improve and extend the ECF APIs in these two areas.
