[aaloa promoters] [Vote] Call for Vote on a project proposal: ZigBee 4 OSGI

Sun Dec 19 20:12:53 CET 2010

  Jesus,

thanks, well I knew about the theoretical limit and also that there are 
many open issues with the mesh topology ...

However regarding competitors, I don't know many other OSS solutions so far.
ProSyst Software provides a commercial solution but it seems they use a 
different design, we are a step forward  by modelling a ZB cluster Library.
We did a search some time ago but we found only "empty" projects (mainly 
on sourceforge).
In any case they were based only to provide a classical ZigBee driver 
interface, while our approach follows the OSGi Access Specification.

I know that soon will be ready the ZigBee Gateway specification (with WS 
and restful interfaces) ,
they had some preliminary test in Irland in these weeks, but our 
solution is different  and most importantly can be used to implement 
their specification.

There are also rumours of a new OSGi ZigBee Device specification, but 
the CNR is not member of OSGi Alliance so we cannot participate to the 
Working Group.
By the way we hope to be involved at least in the proposal submission.
Occasionally,  in this regard there is an interesting comment to the 
post of Peter Kriens: "JCP is dead"
http://www.osgi.org/blog/2010/12/jcp-is-dead.html

WDYT ? Will OSGi change his policy?  ;-)

Francesco
