# Internationale Zulassungsdokumente: Länder- und Feldmapping

Diese Matrix erläutert die dokumentierten Antwortfelder für internationale Zulassungsdokumente.

Die Matrix umfasst die EU-27, Island, Liechtenstein, Norwegen, die Schweiz und das Vereinigte Königreich. Bei nicht aufgeführten Ländern können Umfang und Zuordnung abweichen.

## API-Endpunkt

`POST /scanner/document/registration/international` akzeptiert ein öffentlich abrufbares Bild oder PDF. `imageUrl` und `imageURL` bleiben Request-Aliase; für neue Integrationen ist `fileUrl` kanonisch. Die persönliche Dokumentanalyse bietet ausschließlich `quality=standard`; andere Qualitätsstufen sind kein gültiger Vertragswert. Der bisherige Pfad `/scanner/registration-document/v2` bleibt als veralteter Kompatibilitätsalias erhalten und antwortet ohne HTTP-Weiterleitung mit demselben Vertrag.

```json
{
  "fileUrl": "https://example.com/registration-document.pdf",
  "quality": "standard"
}
```

Die erfolgreiche Antwort ist direkt das internationale Objekt, ohne den nationalen Umschlag `{status,data}`. Der nationale Vertrag liegt kanonisch unter `/scanner/document/registration`; der bisherige Pfad `/scanner/registration-document` bleibt als veralteter Kompatibilitätsalias mit identischer Antwort verfügbar.

## Antwortkonvention

- `fields[].name` ist immer die kanonische englische Feldbezeichnung.
- `fields[].code` ist der kanonische semantische Schlüssel; `fields[].sourceCode` enthält den tatsächlich aufgedruckten Feldcode oder `null`.
- `fields[].value` ist bei sprachabhängigen Kategorien auf Englisch normalisiert. Eigennamen, Adressen, Kennzeichen, VIN, Hersteller und Modellbezeichnungen bleiben unverändert.
- `fields[].sourceValue` bewahrt bei Übersetzung oder Normalisierung den unveränderten Aufdruck.
- Datumswerte der normalisierten Kernfelder sind ISO-8601-Werte; Messwerte werden ohne Einheit als normalisierte Dezimalzeichenfolge geliefert.
- Jedes lesbare, nicht nur jedes kanonisch bekannte Feld wird zusätzlich in `fields[]` ausgegeben. Unbekannte nationale Felder erhalten `scope: national`.

## Breite Feldmatrix (34 Spalten)

Ein Feldcode in einer EU-/EWR-Spalte bedeutet eine harmonisierte **Semantik**, nicht dass das optionale Feld auf jedem konkreten Dokument gedruckt sein muss. Dokumentaufteilung, Reihenfolge, Sprache und Layout bleiben national. Die Schweiz wird primär anhand der gedruckten Bezeichnung gelesen; nummerierte Zellen sind der bekannte Schweizer Crosswalk.

¹ Der aktuelle V5C-Aufdruck `[X]` bezeichnet die britische **Taxation class** und darf nicht als harmonisiertes Feld `X` (roadworthiness validity) interpretiert werden.

² EU-abgeleiteter V5C-Code, sofern er auf der jeweiligen Ausgabe gedruckt ist. Britische Zusatzfelder werden unabhängig davon als `national` ausgegeben.

³ Labelbasierte Zuordnung. Bei Schweizer Zellen mit `≈` ist das Schweizer Feld nur die nächstliegende kanonische EU-Semantik; `sourceCode` und `sourceValue` bleiben maßgeblich.

Für Island, Liechtenstein und Norwegen gilt das harmonisierte Mapping aufgrund der Übernahme in das EWR-Recht. Das später hinzugefügte Feld `V.10` ist im EWR jedoch nicht automatisch in jeder nationalen Ausgabe vorhanden.
