About this source
Search the CELLAR corpus behind EUR-Lex by document type, date, EuroVoc subject and institution; resolve CELEX numbers and ELI citations; fetch metadata and full text of regulations, directives and decisions; search CJEU and General Court judgments and Advocate General opinions; traverse what an act amends, repeals or is based on; and run read-only SPARQL for anything the curated tools miss. Every answer carries a CELEX identifier.

What the assistant can do with it
The 7 tools this server offers to Kahubi. The assistant picks the right one for each question.
eurlex_lookup_celexResolve an EU legal citation - a CELEX number or ELI URI - to its canonical CELLAR work, confirming it exists before you fetch or traverse it.
eurlex_browse_subjectsSearch the EuroVoc thesaurus, resolving a keyword into concept URIs usable in the eurovoc_concept subject filter of eurlex_search_documents.
eurlex_search_documentsSearch EU legislation, treaties, and preparatory acts across the CELLAR corpus by document type, date range, EuroVoc subject, author institution, and in-force status.
eurlex_get_casesSearch CJEU and General Court case law - judgments, orders, and Advocate General opinions - by case number, court, case type, keyword, and date range.
eurlex_get_documentFetch the metadata and full text of an EU act by CELEX number, ELI URI, or work URI.
eurlex_get_relationsTraverse the one-hop CDM relationship graph of an EU act: what it amends or is amended by, what it repeals or is repealed by (explicit and implicit), its consolidated versions,...
eurlex_query_sparqlRun a raw, read-only SPARQL SELECT against the CELLAR Virtuoso endpoint - an escape hatch for CDM ontology traversals the curated tools do not cover.
