Alias System (BCP 47 Locale Tags)

Identity aliases support multilingual display names. Aliases are stored in metadata.aliases as an array of {locale, name} objects.

BCP 47 Locale Tags Reference

Locale Tag Example
English en John Smith
Traditional Chinese zh-TW 約翰·史密斯
Simplified Chinese zh-CN 约翰·史密斯
Japanese ja ジョン・スミス
Korean ko 존 스미스
Cantonese yue 約翰·史密夫
French fr John Smith (French spelling)
Spanish es Juan Smith
Arabic ar جون سميث
Russian ru Джон Смит
Thai th จอห์น สมิธ

BCP 47 is the IETF standard for language tags. Format: language (e.g. en, ja) or language-Region (e.g. zh-TW, zh-CN).

Frontend Display Logic

function getDisplayName(identity, preferredLocale) {
  const match = identity.metadata?.aliases?.find(a => a.locale === preferredLocale);
  if (match) return match.name;
  const lang = preferredLocale.split('-')[0];
  const langMatch = identity.metadata?.aliases?.find(a => a.locale.startsWith(lang));
  if (langMatch) return langMatch.name;
  return identity.name;
}

Updating Aliases via PATCH

PATCH /api/v1/identity/:identity_uuid
{
  "metadata": {
    "aliases": [
      {"locale": "en", "name": "John Smith"},
      {"locale": "zh-TW", "name": "約翰·史密斯"}
    ]
  }
}
