Igrantio Dcql Query Pda1

DCQL query: Portable Document A1 (PDA1)

When to use

Use this template when a worker must show which member state social security legislation applies to them. The Portable Document A1 is the EU form for posted workers and for people who work in two or more member states. The query follows the six sections of the paper form:

• section1 - the person: surname, surname at birth, forenames, birth date, place of birth, sex, nationalities, personal identification number, and the addresses in the state of residence and the state of stay;
• section2 - the legislation that applies: the member state, the starting date and the ending date;
• section3 - the reason: posted employed person, posted self-employed person, work in two or more states, mariner, flight crew member, civil servant, contract staff, an exception, and the description of the exception;
• section4 - the employer or the self-employed activity: name or business name, registered address, and the activity codes;
• section5 - the workplaces: the names and the addresses;
• section6 - the institution that filled the form: name, institution identifier, address, date, email, office phone number, office fax number, and signature.

Typical uses are labour inspection at a site, contractor onboarding, and cross-border payroll checks.

An inspection often needs section 1 and section 2 only: who the person is, and which legislation applies during which period. Ask only for the sections that your check needs.

Template facts

Registry version: 2025.7.1.

The doctype and the namespace differ for mso_mdoc. The doctype names the document, org.iso.18013.5.1.pda1. The namespace groups the data elements, org.iso.18013.5.1.

  ]
}

The registry also holds an older mso_mdoc file that names each claim with a namespace and a claim_name pair. It lists the same six claims. Use the path form above for a version_01 presentation definition.

How to read the path arrays

The path array names one claim, one element per level.

• dc+sd-jwt: the path starts at the top level of the SD-JWT VC payload. ["section2", "startingDate"] reads the startingDate member inside the section2 object. Each section appears twice in the list: once as the whole object, and once per member. Ask for the whole section when you want every field of it. Ask for single members when you want less.
• jwt_vc_json: the path starts with credentialSubject, because a W3C VC keeps the subject claims under that key. Every path is one element longer than the dc+sd-jwt path for the same claim.
• mso_mdoc: the path holds exactly two elements. The first element is the namespace, here org.iso.18013.5.1. The second element is the data element name. An mdoc has no nesting below the data element, so each section arrives as one whole object. You cannot ask for startingDate alone in mso_mdoc. You ask for section2, and you get every field of it.

This difference matters for data minimisation. The SD-JWT VC and W3C VC forms let you ask for single fields. The mdoc form does not.

Use with the iGrant.io API

Create a presentation definition with POST /v2/config/digital-wallet/openid/sdjwt/presentation-definition. Put the claims of one format into one entry of dcqlQuery.credentials[]. Give the entry an id, set format, and set meta for that format:

The format gates the meta keys. The server refuses vct_values on jwt_vc_json and refuses anything but doctype_value on mso_mdoc.

Set version to version_01.

{
  "label": "Posted worker check",
  "version": "version_01",
  "responseType": "vp_token",
  "responseMode": "direct_post",
  "dcqlQuery": {
    "credentials": [
      {
        "id": "pda1",
        "format": "dc+sd-jwt",
        "meta": { "vct_values": ["PortableDocumentA1"] },
        "claims": [
          { "path": ["section1", "surname"] },
          { "path": ["section1", "forenames"] },
          { "path": ["section1", "dateBirth"] },
          { "path": ["section2"] }
        ]
      }
    ]
  }
}

Then send the verification request with the V3 send operation, POST /v3/config/digital-wallet/openid/sdjwt/verification/send, and pass the presentationDefinitionId of the record that you created. Read the disclosed claims from presentation on the verification history record.

The igrantio-api-verifier skill holds the full operation reference: every field of the presentation definition, every transport option, and the shape of the verification history record.

Source is the registry

The iGrant.io verifiable data registry is the source of truth for this template. If this skill and the registry file disagree, the registry wins. Fetch the source directory before you rely on a claim path:

• https://github.com/decentralised-dataexchange/verifiable-data-registry/tree/main/presentationDefinitions/dcqlQuery/pda1
• Raw file: https://raw.githubusercontent.com/decentralised-dataexchange/verifiable-data-registry/main/presentationDefinitions/dcqlQuery/pda1/2025.7.1/dc%2Bsd-jwt.schema.json

Follow the registry and report the drift so this skill can be corrected.
