=== Classification ===

{| class="wikitable"
|-
! CELEX nature code !! → <code>nature</code>
|-
| R || <code>REGLEMENT</code>
|-
| L || <code>DIRECTIVE</code>
|-
| D || <code>DECISION</code>
|-
| H || <code>RECOMMANDATION</code>
|-
| X || <code>ACCORD_INTERNATIONAL</code>
|}

<code>type</code> = <code>statute</code> (always). <code>number</code> derived from CELEX pattern (e.g. <code>2016/679</code>).

=== Enforcement ===

{| class="wikitable"
|-
! <code>enforcement_status</code> !! <code>in_force</code> !! Signal
|-
| <code>in_force</code> || true || SPARQL in-force signal present
|-
| <code>repealed</code> || false || end_of_validity is past
|}

Only these two values are emitted (full vocabulary defined in TAG-CONVENTIONS but not used by this source).

<code>needs_review</code> = <code>"enforcement_status_missing"</code> (no signal) or <code>"enforcement_status_contradiction"</code> (in-force=true but end-of-validity is past).

=== Structure ===

{| class="wikitable"
|-
! Record type !! kind !! Notes
|-
| Root text node || section || <code>structure_type: "legislation"</code>, <code>text_id</code> = cross-language canonical ID
|-
| Chapter || section || parent = text root
|-
| Sub-section || section || parent = chapter
|-
| Article || legislation || parent = nearest enclosing section
|-
| Preamble || legislation || <code>article_number: "PREAMBULE"</code>
|}

=== Identifiers ===

{| class="wikitable"
|-
! Tag !! Notes
|-
| <code>celex</code> || CELEX identifier
|-
| <code>text_id</code> || cross-language canonical work ID (no <code>:lang</code> suffix)
|}

=== Multilingual ===

Each language version is a separate row with <code>:{lang}</code> suffix. <code>translation_pending</code> set when content was fetched in EN fallback.

== Edges ==

{| class="wikitable"
|-
! <code>kind</code> !! Direction !! Trigger
|-
| <code>language_variant</code> || EN ↔ FR || post-ingest LLM translation enrichment
|}

== Related sources ==

{| class="wikitable"
|-
! Source !! Relationship
|-
| [[Sources/EU/CJEU|cjeu]] || CJEU decisions interpret EU legislation. No cross-source edges yet.
|}

== Limitations ==

* Only <code>language="fr"</code> ingested — multi-language support planned
* Only R, L, D, H, X nature codes — other CELEX types not ingested
* No citation edges between EU legislative acts
* Legacy/PDF format documents produce a single article (no structural breakdown)
