EU texts exist in 24 official languages. The corpus may contain multiple language versions of the same text — they are equivalent in legal value (TFEU art. 55).

'''Multilingual ingestion''': each language version is a separate row with a <code>:lang</code> suffix in the
document ID (e.g. <code>EU.EURLEXTEXT32016R0679:fr</code> and <code>EU.EURLEXTEXT32016R0679:en</code> for the French
and English versions of the GDPR). The cross-language identifier <code>tags.text_id</code> is unsuffixed
(<code>EU.EURLEXTEXT32016R0679</code>), so resolver lookups by <code>text_id</code> find all language versions; the
<code>language</code> parameter you pass to the tools narrows results to the user's language. Documents
ingested in a fallback language (e.g. EN-only when no FR is available) carry
<code>tags.translation_pending="fr"</code> and may receive a machine translation later.
