The Curricular and Academic (CAOS) web services, formally known as the Course Roster Information Service (CRIS), is a set of web services that provides curricular, roster and student data to authorized recipient systems. Data is organized under three areas - Curricular, Course Roster and Course Roster with Student. Curricular information includes data on courses and their relationships. Course roster information supplements the curricular data by also providing a list of section enrollees and instructors. Course Roster with Student access provides curricular, course roster, student and advisor data.
