Isn't the right way to do this using Accept headers?
The resource is the same, its just the representation that differs.

We can use get method of Registry to get resource as well as get
comments and so on , so one can do something like following
registry.get("/c1/c2") --> Return the resource to get resource and
in the same time if he want to get the comments he can use the get
method with the following path
registry.get("/c1/c2;comments) --> Return the resource with comments;
So Registry like JDBC and Secure know how to process that.
However in the Remote registry we have some issues commands when
someone called getComments() . For example when someone use remote
registry and when he calls registry.getComments() we send a request like
http://localhost:8080/wso2registry/c1/c2;comments
And in the meantime he can use the get API to send the same request
(http://localhost:8080/wso2registry/c1/c2;comments),
remoteRegistry.get( http://localhost:8080/wso2registry/c1/c2;comments)
-> wire URL " http://localhost:8080/wso2registry/c1/c2;comments";
remoteRegistry.getComments(http://localhost:8080/wso2registry/c1/c2); ->
wire URL " http://localhost:8080/wso2registry/c1/c2;comments";
so when it come to server side I can not differentiate the two , though
I need to do so.
This problem happen we use the same parameter separator both in APP and
normal registry , if we can use two characters then we can solve the
problem. Therefore at the moment I am using "$" as the parameter
separator in APP (according to the wiki I am supposed to use ";" )

Hi all ,
I have implemented APP using "$" (considering the mail thread) as the
query parameters , so if you want to get the comments we need to send a
request like
/c1/c2$comments
However when I switch to /c1/c2;comments instead of /c1/c2$comments I
found an issue in the app impl . Because in the registry get api has
support for /c1/c2;comments , so rather than using getComment method one
can use get method to get the comments. This become big issue when it
come to remote registry , where I can not differentiate the two , though
it is required to do so. So how about using a different query parameter
character for get method of the registry API?

I have created a wiki page for registry protocol at
http://www.wso2.org/wiki/display/registry/Registry+Protocol
Registry URL space and the APP based message formats discussed in the
Registry hackathan are included in the wiki.
Thanks,
