📝Input descriptors

Input descriptors are used to specify the data or credentials needed to issue a credential. It is a main feature of DIF Presentation Exchange. See https://identity.foundation/presentation-exchange/#presentation-definition for more information.

An example here with only input descriptors (EmailPass required to issue a credential) :

{
"credential_manifest": {
  "presentation_definition": {
    "id": "32f54163-7166-48f1-93d8-ff217bdb0653",
    "input_descriptors": [
      {
        "id": "emailPass_input_1",
        "constraints": {
          "fields": [
            {
              "path": [
                "$.type"
              ],
              "filter": {
                "type": "string",
                "pattern": "EmailPass"
              }
            }
          ]
        }
      }
    ]
  }
  }
}

Example to request any credentials with the attribute birthDate

  "presentation_definition": {
    "id": "32f54163-7166-48f1-93d8-ff217bdb0653",
    "input_descriptors": [
      {
        "id": "#765765",
        "constraints":
          "fields": [
            {
              "path": [
                "$.credentiaSubject.birthDate"
              ]
            }
          ]
        }
      }
    ]
