I think it would be like:
HTTP GET /rpc/?v=5&type=provides&arg[]=java-environment&arg[]=libgala.so
{"version":5,"type":"provides","resultcount":2,"results":
 "java-environment": [] // might be list of package names or list of "info"
 "libgala.so": []
}

I got the reasoning about it.
Still, versioned dependencies are valid in the depends array,
so I'd like the provides search in the RPC mentioned above support this,
much like the Dependencies section in the web interface [1].
