One row of the `course_catalog` dataset (DCAT identifier PM_course_catalog, \"Polimi - Catalogo Corsi di Laurea\") — degree programmes with at least one enrolment event in the last 10 academic years or one graduation event in the last 10 calendar years. Field names are the institution's own Italian labels, taken verbatim from the live JSON distribution (157 rows) on 2026-09-01. Types were inferred from observed values; the institution publishes no schema.",
