I know you are expecting a response from me (I've talked to Dims about this 
already) so I might as well get it out of the way....  :-)

So, basically, you wanted a JAX-RS implementation.  You looked at Apache CXF 
but it didn't completely meet your needs.   Instead of engaging with CXF 
(there wasn't any discussion about any of this on the CXF dev/users list) to 
enhance CXF, you fork it in house and update it and enhance it outside of any 
community.   Now you want to push it back into Apache, but not with any of the 
CXF community.    I just wanted to get that out in the open.    Two 
implementations isn't a bad thing (think Axis2 and CXF) but the way this was 
approached is a concern.

Next come the hard questions:
1) The proposal mentions it's already JAX-RS TCK compliant.   From a JAX-RS 
standpoint, were do you see the community "growing"?   I've seen several 
projects that come in with their stated goals already "complete" and have a 
tough time getting new committers.    

2) What "advantages" would it have over CXF's implementation and/or Jersey?  
(apart from the TCK compliance which CXF is working on now that we got the 
TCK)  Since Wink would be Apache licensed, I'd expect anything "cool" would be 
pulled into CXF anyway if possible.    One advantage of multiple Apache 
licensed implementations is that great ideas can also be pulled back and 
forth.   :-)        Obviously, I haven't seen the Wink code so I don't know 
how easy/hard that would be.

One "question" I have when I see projects with duplicate goals is to see if 
the differences could be resolved to a point where only one project is needed.   
I remember with CXF and Axis 2 sitting down in a room at some conference 
several years ago (ApacheCon Austin maybe?  Don't really remember.) with Dan 
Diephouse, myself, Glen Daniels, Sanjiva and several others involved with both 
projects to try and resolve any issues and possibly merge things.    In that 
meeting, we really did conclude we had strong differences in opinions on 
designs, priorities, and ideas and it really wasn't possible.   That is quite 
OK.   At least the discussion occurred.     I haven't seen discussions like 
that with CXF/Wink.  


I guess from my standpoint, while I'm not "against" the proposal, I'd 
definitely like to see it have the option of "graduating" via a merger with 
the CXF implementation and engagements with that community.
