ARIS Object type for Centrasite integration

Hi Experts,

We are trying to integrate ARIS 9.8 with Centrasite 9.8. I have the following questions:

  1. Which object type should be used in ARIS to define the service attributes so that i can push it to Centrasite

        Should i use the 
        a) "Application System type" object or
        b) "Service Type" object or
        c) "IS Service" object
  2. Is it a 2 way integration between ARIS & Centrasite, can i define a new service in ARIS and publish it to Centrasite.
