Base Candidate Class 

...

 3) Vfmodule

 4) Transport

 5) NSSI

All the candidate for every inventory types extend from the candidate base class.

(Should the fields in models (cloud_info, complex_info, location_info ..) come from the configuration (or) should be defined in the models itself as instance variables  (or) should the fields be derived from AAI)Following are the AAI objects from which the respective candidates takes the required data:

Design

In the data module, after fetching the data from AAI the candidate gets populated like this 

{
   "candidate_id":"1ac71fb8-ad43-4e16-9459-c3f372b8236d",
   "candidate_type":"service",
   "inventory_type":"service",
