Link between Evidence and Claims

OIDF JP and Mike Engan brought up this topic. They would like to explicitly represent the relationship between the evidence used to verify a certain claim and the respective claim. The need exists only happen in situations with multiple evidence.

I suggest to add an optional array claimsto the evidence element containing references to the claims in the claims section as shown in the following example:

{

  "verified_claims":{

    "verification":{

      "trust_framework":"de_aml",

      "date":"2013-02-21",

      "verification_process":"676q3636461467647q8498785747q487",

      "evidence":[

        {

          "type":"id_document",

          "method":"pipp",

          "document":{

            "document_type":"de_erp_replacement_idcard",

            "issuer":{

              "name":"Stadt Augsburg",

              "country":"DE"

            },

            "number":"53554554",

            "date_of_issuance":"2012-04-23",

            "date_of_expiry":"2022-04-22"

          },

          "claims":["given_name","familiy_name","birthdate","place_of_birth","nationality"]

        },

        {

          "type":"utility_bill",

          "provider":{

            "name":"Stadtwerke Musterstadt",

            "country":"DE",

            "region":"Thüringen",

            "street_address":"Energiestrasse 33"

          },

          "date":"2013-01-31",
          "claims":["address"]

        }

      ]

    },

    "claims":{

      "given_name":"Max",

      "family_name":"Meier",

      "birthdate":"1956-01-28",

      "place_of_birth":{

        "country":"DE",

        "locality":"Musterstadt"

      },

      "nationality":"DE",

      "address":{

        "locality":"Maxstadt",

        "postal_code":"12344",

        "country":"DE",

        "street_address":"An der Sanddüne 22"

      }

    }

  }

}
