# Igrantio Dcql Query Mobile Driving License > DCQL query template for the ISO 18013-5 Mobile Driving Licence (mDL), doctype org.iso.18013.5.1.mDL in mso_mdoc. It asks a wallet for the 25 mandatory and optional data elements of the org.iso.18013.5.1 namespace, from family_name and driving_privileges to portrait, age_over_18 and un_distinguishing_sign. Use this skill when you build car rental, roadside checks, vehicle hire or an age gate on an mDL, and you need the exact doctype, namespace and claim paths from the iGrant.io verifiable data registry. - Skill: `l3-igrant/igrantio-dcql-query-mobile-driving-license` (Agent Skill) - Install (CLI): `npx skillmds@latest add l3-igrant/igrantio-dcql-query-mobile-driving-license` - Raw SKILL.md: https://api.skillmd.com/api/skills/l3-igrant/igrantio-dcql-query-mobile-driving-license/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - License: Apache-2.0 - Author: L3-iGrant (https://skillmd.com/u/l3-igrant) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/l3-igrant/igrantio-dcql-query-mobile-driving-license --- # DCQL query: Mobile Driving Licence (mDL) ## When to use Use this template when you must check a driving licence that a wallet holds. The query lists the 25 data elements of the ISO 18013-5 mDL: the holder name and birth data, the document number and dates, the issuing authority and country, the driving privileges, the portrait, and the physical description. Typical uses are car and van rental, vehicle hire desks, roadside checks, and an age gate that uses the `age_over_18` or `age_over_21` flag of the licence. The full list is large and holds a portrait and a home address. Ask only for the data elements that your check needs. A rental desk often needs the name, the document number, the expiry date and the driving privileges, and nothing else. For an age gate alone, prefer the Age Verification attestation, which discloses one boolean flag. See `igrantio-dcql-query-age-verification`. ## Template facts Registry version: **2026.4.1**. | Fact | Value | | --- | --- | | Title | Mobile Driving Licence (mDL) | | Purpose | Mobile Driving Licence (mDL) | | Credential type (doctype) | `org.iso.18013.5.1.mDL` | | Namespace | `org.iso.18013.5.1` | | Format | `mso_mdoc` | The registry holds one format for this template. There is no SD-JWT VC file and no JWT VC file. The mDL is an ISO 18013-5 document, and `mso_mdoc` is its native format. The doctype and the namespace differ. The doctype names the document, `org.iso.18013.5.1.mDL`. The namespace groups the data elements, `org.iso.18013.5.1`. ## Claims ### Format `mso_mdoc` ```json { "claims": [ { "path": ["org.iso.18013.5.1", "administrative_number"] }, { "path": ["org.iso.18013.5.1", "age_birth_year"] }, { "path": ["org.iso.18013.5.1", "age_in_years"] }, { "path": ["org.iso.18013.5.1", "age_over_18"] }, { "path": ["org.iso.18013.5.1", "age_over_21"] }, { "path": ["org.iso.18013.5.1", "birth_date"] }, { "path": ["org.iso.18013.5.1", "birth_place"] }, { "path": ["org.iso.18013.5.1", "document_number"] }, { "path": ["org.iso.18013.5.1", "driving_privileges"] }, { "path": ["org.iso.18013.5.1", "expiry_date"] }, { "path": ["org.iso.18013.5.1", "eye_colour"] }, { "path": ["org.iso.18013.5.1", "family_name"] }, { "path": ["org.iso.18013.5.1", "given_name"] }, { "path": ["org.iso.18013.5.1", "hair_colour"] }, { "path": ["org.iso.18013.5.1", "height"] }, { "path": ["org.iso.18013.5.1", "issue_date"] }, { "path": ["org.iso.18013.5.1", "issuing_authority"] }, { "path": ["org.iso.18013.5.1", "issuing_country"] }, { "path": ["org.iso.18013.5.1", "issuing_jurisdiction"] }, { "path": ["org.iso.18013.5.1", "portrait"] }, { "path": ["org.iso.18013.5.1", "portrait_capture_date"] }, { "path": ["org.iso.18013.5.1", "resident_address"] }, { "path": ["org.iso.18013.5.1", "sex"] }, { "path": ["org.iso.18013.5.1", "un_distinguishing_sign"] }, { "path": ["org.iso.18013.5.1", "weight"] } ] } ``` ## How to read the `path` arrays For `mso_mdoc`, the `path` array holds exactly two elements: 1. the **namespace**, here `org.iso.18013.5.1`; 2. the **data element name**, here the mDL data element. An mdoc has no nesting below the data element. `driving_privileges` arrives as one whole structure with every licence category, the issue date and the expiry date of each. You cannot ask for one category alone. ## Use with the iGrant.io API Create a presentation definition with `POST /v2/config/digital-wallet/openid/sdjwt/presentation-definition`. Put the claims into one entry of `dcqlQuery.credentials[]`. Give the entry an `id`, set `format` to `mso_mdoc`, and set `meta.doctype_value` to `org.iso.18013.5.1.mDL`. `mso_mdoc` allows `doctype_value` only. The server refuses `vct_values` and `type_values` for this format. Set `version` to `version_01`. ```json { "label": "Driving licence check at pickup", "version": "version_01", "responseType": "vp_token", "responseMode": "direct_post", "dcqlQuery": { "credentials": [ { "id": "mdl", "format": "mso_mdoc", "meta": { "doctype_value": "org.iso.18013.5.1.mDL" }, "claims": [ { "path": ["org.iso.18013.5.1", "family_name"] }, { "path": ["org.iso.18013.5.1", "given_name"] }, { "path": ["org.iso.18013.5.1", "document_number"] }, { "path": ["org.iso.18013.5.1", "expiry_date"] }, { "path": ["org.iso.18013.5.1", "driving_privileges"] } ] } ] } } ``` 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 data elements from `presentation` on the verification history record. For a same-device check in a browser, the presentation definition also supports the ISO 18013-7 Annex C profile. That profile needs a different `version` value, `trustAnchor` set to `x509`, and `expectedOrigins`. Read `igrantio-api-verifier` before you use it. 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.
