eu-sparql-searchlisted

Search EU legislation, publications and CJEU case law using the Publications Office SPARQL endpoint and Cellar knowledge graph (CDM ontology). Use this skill whenever the user wants to find EU acts (regulations, directives, decisions), search EUR-Lex by CELEX number, date or subject, retrieve CJEU rulings, download EU documents in specific languages or formats, or build SPARQL queries against https://publications.europa.eu/webapi/rdf/sparql. Also trigger when the user asks about EU law programmatically, wants to query Cellar metadata, or mentions CDM ontology, EUR-Lex, EU publications, or SPARQL + EU/legislation.
