Igrantio Credential Schema Photo Id

Photo ID - credential schema

When to use

Use this skill when you issue or verify a Photo ID credential. Photo ID is the photo identity document of the EUDI Wallet. It carries the person data of an identity document, the portrait, and, when the issuer has them, the data groups of a digital travel credential.

The registry gives the credential type eu.europa.ec.eudi.photoid.1 and the same value as the namespace. The schema supports three formats: SD-JWT VC (dc+sd-jwt), W3C JWT VC (jwt_vc_json) and mdoc (mso_mdoc).

The registry keeps this schema under credentialSchemas/claimPathPointer/photoId. Version 2025.7.1 is the latest version directory, and this skill uses it. The registry publishes the schema in three formats: dc+sd-jwt, jwt_vc_json and mso_mdoc.

What the claims describe

The claims sit in three groups. Every claim in this schema is mandatory.

• iso23220 - the core person data of ISO/IEC 23220. Names in two encodings (given_name_latin1, family_name_latin1, given_name_unicode, family_name_unicode), name_at_birth, birth_date, birthplace, nationality, sex, portrait and portrait_capture_date. Age data: age_in_years, age_birth_year and the age_over_18 flag. Document data: issue_date, expiry_date, issuing_country and issuing_authority_unicode. Residence data: resident_address_unicode, resident_city_unicode, resident_postal_code and resident_country.
• photoid - the extra identity claims of the Photo ID document. person_id, administrative_number, travel_document_number, the birth place parts birth_city, birth_state and birth_country, and the residence parts resident_street and resident_state.
• dtc - the digital travel credential. dtc_version, dtc_sod, dg_content_info, and the data groups dtc_dg1 through dtc_dg16.

Send age_over_18 when you want the holder to prove an age limit without a birth date. Send portrait as the image of the holder.

mdoc (mso_mdoc)

The first element of every path is eu.europa.ec.eudi. That value is the mDoc namespace of the claims. It is not the same string as the doctype eu.europa.ec.eudi.photoid.1. Send the doctype in the doctype field, and keep eu.europa.ec.eudi as the first path element, as the registry has it. The group name (iso23220, photoid or dtc) is the second element.

How to read a claim path pointer

A claim path pointer selects one claim in the credential. Each item of the claims array holds these fields.

• path is mandatory and holds at least one element. Read the elements from left to right. A string element selects an object key. An integer element selects one array index. A null element selects every element of an array, so ["nationalities", null] covers each entry of the nationalities array.
• mandatory says whether the issuer must supply a value for the claim. The issuer reads a missing mandatory field as true.
• limitDisclosure says that the holder can disclose the claim on its own. Set it only inside the claims object of a dc+sd-jwt or mso_mdoc configuration. The jwt_vc_json format has no selective disclosure, so its documents leave the field out.

A path that names a parent object, such as ["address"], and a path that names a child, such as ["address", "country"], can both appear. The parent pointer lets the holder disclose the full object. The child pointers let the holder disclose one field at a time.

For mso_mdoc, the first element of the path is the mDoc namespace, every path holds at least two elements, and every path of one configuration uses the same first element.

For jwt_vc_json, the first element of the path is always credentialSubject.

Use with the iGrant.io API

Create a credential definition with POST /v2/config/digital-wallet/openid/sdjwt/credential-definition. Put the claims array of the registry document into the configuration entry, and set the format fields that the table above gives.

{
  "label": "Issue Photo ID",
  "version": "version_01",
  "credentialDefinitions": [
    {
      "credentialFormat": "dc+sd-jwt",
      "vct": "eu.europa.ec.eudi.photoid.1",
      "validationPath": "$",
      "claims": {
        "claims": [
          {
            "path": [
              "dtc",
              "dg_content_info"
            ],
            "limitDisclosure": true,
            "mandatory": true
          },
          {
            "path": [
              "dtc",
              "dtc_dg1"
            ],
            "limitDisclosure": true,
            "mandatory": true
          }
        ]
      }
    }
  ]
}

The label Photo ID Issuance is reserved for the platform. Pick another label, for example Issue Photo ID.

Notes on the request.

• label must hold at least 3 characters. The platform reserves the labels Payment User Credential, Payment Card Credential, Payment Account Credential, PID Issuance and Photo ID Issuance, so pick another label.
• Always send version with the value version_01. The issuer falls back to an earlier version of the specification when you leave the field out, and you cannot change the value after you create the credential definition.
• Add one entry of credentialDefinitions[] for each format that you want to publish. You can publish more than one format from one credential definition.
• Keep the id that the response returns for each entry. The issue operation uses that value to match the claims to a configuration.
• Add supportRevocation, revocationMethod, expirationInDays, display and the other entry fields as your use case needs them.

Read igrantio-api-issuer for the full operation reference, the other request fields, and the issue operation that follows.

Source is the registry

The verifiable data registry is the source of truth. If this skill and the registry file disagree, the registry wins. Fetch the source before you rely on a claim path, and report the difference so this skill can be corrected.

• Template directory: https://github.com/decentralised-dataexchange/verifiable-data-registry/tree/main/credentialSchemas/claimPathPointer/photoId
• Raw dc+sd-jwt document: https://raw.githubusercontent.com/decentralised-dataexchange/verifiable-data-registry/main/credentialSchemas/claimPathPointer/photoId/2025.7.1/dc+sd-jwt.schema.json
• The metadata file sits next to each schema file, with the suffix .schema.metadata.json. It carries the title, the credential type, the doctype and the format flags.
