Manoj is communicating with me when he encounters problems. So from that
perspective I am updated.

Last week he showed me a wiki page
(http://wso2.org/wiki/display/wsfphp/API+for+Data+Services) with a
proposal for client API for data service. I saw several dis-advantages in
this approach & told him so.

Disadvantages
1. Client becomes data service specific (In java impl, client is not aware
of the fact he/she is calling a data service. Its just a web service call
for him)

2. Configuration details which are part of .dbs file in java impl, are
being passed from client when calling the service.

3. Java client will not be able to interop with PHP based data service.

4. Concept of creating a data service using contents in the configuration
file (.dbs) seems to be violated.


As per the last conversation I had with him, the code is written in mysql
specific manner. So explained the generic approach taken by java
implementation & discussed how PHP impl can take a similar pattern.

So far I haven't tried a working version from a user perspective. Should
try that myself.

But I feel Manoj is making progress.
