The Rating API is used to define rules of how to calculate rating for objects.

Rating Configuration has the following format:

{
   "timestamp": 12345,
   "sources":{
      "configuration/sources/FB":[
         {
            "uris":[
               "configuration/relationTypes/HasAddress",
               "configuration/relationTypes/Employment"
            ],
            "minVoteWeight":2.0,
            "maxVoteWeight":5.0,
            "monthsToMinWeight":4.0
         },
         {
            "minVoteWeight":1.0,
            "maxVoteWeight":2.0,
            "monthsToMinWeight":1.0
         }
      ],
      "configuration/sources/LNKD":[
         {
            "uris":[
               "configuration/relationTypes/HasAddress"
            ],
            "minVoteWeight":2.0,
            "maxVoteWeight":5.0,
            "monthsToMinWeight":4.0
         },
         {
            "minVoteWeight":1.0,
            "maxVoteWeight":2.0,
            "monthsToMinWeight":1.0
         }
      ]
   },
   "userRoles":{
      "ROLE_ADMIN":[
         {
            "uris":[
               "configuration/relationTypes/HasAddress"
            ],

It contains rating calculation for source systems inside a relation and for roles of users who made votes. This JSON contains configuration for desired source systems and user roles. Each source system and user role contains weights configuration connected to relation types. Weights configuration may not contain the list of relation types - such configuration is default. The timestamp property contains timestamp of last modification for this configuration.
