OPUS (Observatoire de Paris UWS System) is a job control system developed using the micro-framework bottle.py. The Universal Worker System pattern v1.1 (UWS) as defined by the International Virtual Observatory Alliance (IVOA) is implemented as a REST service to control job execution on a work cluster. OPUS also follows the proposed IVOA Provenance Data Model to capture and expose the provenance information of jobs and results.
