  • eurlex_lookup_celex Resolve an EU legal citation — a CELEX number, ELI URI, ECLI, or an OJ citation naming its act type and year (e.g. "Regulation (EU) 2016/679", "Directive 95/46/EC") — to its canonical CELLAR work, confirming it exists before you fetch or traverse it. Returns the work URI, confirmed CELEX number, doc
  • eurlex_browse_subjects Search the EuroVoc thesaurus, resolving a keyword into concept URIs usable in the eurovoc_concept subject filter of eurlex_search_documents. Matches both preferred and alternative (non-preferred) labels, so a common synonym reaches the concept it stands for. Returns each concept URI, its preferred l
  • eurlex_search_documents Search EU legislation, treaties, and preparatory acts across the CELLAR corpus by document type, date range, EuroVoc subject, author institution, and in-force status. Keyword matches English titles and CELEX strings only — there is no full-text body search. Corrigenda are excluded by default so prim

A case number reaches every judgment, order, and AG opinion filed under it. By default only these primary records are returned; derivative judicial i

Returns structured metadata (title, date, type, author institution, Advocates General, legal basis, EuroVoc subjects, in-force status and, for an act not in force, its repealing acts, end of valid

  • eurlex_query_sparql Run a raw, read-only SPARQL SELECT against the CELLAR Virtuoso endpoint — an escape hatch for CDM ontology traversals the curated tools do not cover. Only SELECT is accepted; update forms and ASK/CONSTRUCT/DESCRIBE are rejected before execution, and results are capped at the server row cap (100 by d
