UCLA Registrar Dictionary API
The largest contract UCLA publishes and the one that makes the rest legible - 61 read operations enumerating every coded value the other SIS APIs return: buildings, careers, cities, colleges, class levels, class numbers, activity types, academic actions, affiliation term sessions, enrolment statuses and fifty more. Owned by the Registrar's Office. Any other campus would call this a code-tables service; publishing it as a first-class API product is the right decision and is unusual in this cohort.
