This checks whether a\nquery scoped to one specific legal act (by CELEX number) behaves differently, and whether EUR-Lex's\nentry-into-force metadata actually answers a point-in-time question cleanly.\n\n## Probe\n```\ncurl -sG \"https://publications.europa.eu/webapi/rdf/sparql\" \\\n  --data-urlencode 'format=application/sparql-results+json' \\\n  --data-urlencode 'query=PREFIX cdm: <http://publications.europa.eu/ontology/cdm#>\n    SELECT ?work ?date_entry_into_force ?date_document WHERE {\n      ?work cdm:resource_legal_id_celex \"32016R0679\"^^<http://www.w3.org/2001/XMLSchema#string> .\n      OPTIONAL { ?work cdm:resource_legal_date_entry-into-force ?date_entry_into_force . }\n      OPTIONAL { ?work cdm:work_date_document ?date_document . }\n    } LIMIT 10'\n```\n\n## Observed\n`HTTP 200` in 0.67 seconds (vs. the existing record's unbounded query not completing in 55s),\n`Content-Type: application/sparql-results+json`, 898 bytes, with **two distinct bindings for the\nsame `work` URI** (`cellar/3e485e15-...`):\n- `date_entry_into_force: \"2016-05-24\"`, `date_document: \"2016-04-27\"` (GDPR's adoption/signature\n  and its nominal entry into force 20 days after publication)\n- `date_entry_into_force: \"2018-05-25\"`, `date_document: \"2016-04-27\"` (the date GDPR actually\n  became *applicable*, two years later, per its own Article 99)\n\nCELLAR's own `cdm:resource_legal_date_entry-into-force` predicate is not single-valued for an act\nwith a delayed application date — it holds both the nominal legal entry-into-force date and the\nlater applicability date as two separate rows for the one work.\n\n## How observed\n2026-10-13T18:29:13Z, direct `curl -G` (GET, parameters in the query string, not a POST body),\nagainst the public Virtuoso SPARQL endpoint, no key.\n\n## Why it matters\nResolves the companion lane K-2 drop (the broad query didn't return): a well-scoped query against\nthis endpoint works fine and fast.
