Hi Ramesh,

thank you very much for your feedback :)

I did not include the JPA extension because I do not have the same extensive 
knowledge about this extension as Chandan. This would make mentoring a student 
hard for me. If Chandan would be willing to help out as a mentor I would 
reconsider this and open an issue.
The same goes for the JavaScript library part. I do not know enough about that 
to feel comfortable mentoring a student working on this.

About Olingo 570: I know this is work in progress but I hope until June when a 
student would start implementing there is a stable version of the metadata 
document in Json. If not there is plenty of other work to be done for the Json 
Serializer like supporting odata.metadta=full. We can adjust the scope if a 
student actually is interested in this issue.

About Olingo 569: Yes a cars sample would be sufficient. Currently the 
implementation is lacking quite a bit of functionality and I don`t have the 
time to work on this. So I had hoped a student would develop this further. 
The feedback to your github idea will follow in another thread.

Finally about  your project idea: I like that very much. We always had an issue 
in V2 with services behaving differently because they interpreted the 
specification differently. Would you like to open an issue for that in the 
JIRA? If yes please tag it with gsoc2015, mentor and java so it appears in the 
global Apache ideas list.  
        
Best Regards,
Christian

Christian,

- How about the JPA extension for V4?
- Java Script library for V4?

OLINGO-570 - this is still work in much progress and there was recent 
discussions in OData TC to make use of JSON Schema but JSON Schema has not been 
fully evolved for the OData needs. 
OLINGO-569 - This is good. Couple comments. The CARS example started is that 
not sufficient? Also as part of discussion OLINGO-482 with Michael B, I wrote 
an alternative extension framework for server side processing, which includes 
the "TripPin" example developed by the Microsoft folks. You can see the example 
and the extended framework here 
https://github.com/rareddy/olingo-odata4/tree/olingo-server-extension/lib/server-core-ext
 . There is separate discussion thread on this. I very much appreciate any feed 
back on that.

Also, OData TC, there has been some talk on developing a library of tests that 
can 
 - Test the conformance level
 - Specification Adherence
 - Cross vendor compatibility

Using the same example service that is implemented by all the framework 
implementors, think like TCK tests for Java. I was hoping, to evolve the above 
TripPin service test into such a test suite, but it does require lot more time 
than I can spare right now. That can be a good project for GSoC student to 
develop into a testing tool. This could be web based or series of JUnit tests 
etc.

Thanks. 

Ramesh..
