USOS is a student management information system used in Polish institutions of higher education.
The USOS API provides a RESTful interface for interacting with data on courses, users, faculties geographics, and much more. Functionality such as data storage and messaging may be automated as well. Default response format is JSON, though XMLMAP and XMLITEMS are supported to translate JSON data to XML. JSONP is supported for callbacks, though CORS is preferred.
