IVOA Grid & Web Services: Asynchronous servicesContentsOverviewServices are defined as being asynchronous when an operation on a web service starts some activity and returns immediately, leaving the activity running remotely. This asychronicity is useful in making a robust VO and is already used in some VO prototypes, e.g. Astrogrid's Common Execution Architecture (CEA). A conceptual proposal for managing the activities was drawn up and presented to IVOA in 2004. This was formalized into the Universal Worker Service (UWS) pattern.Universal Worker ServiceUWS proposes that a minimal interface supports job creation, polling of job status and retrieval. A fuller interface would also allowing requesting an estimate of the duration of a job amd restarting a failed job from its last checkpoint. UWS-PA is an instantiation of the UWS pattern for parameterized applications (PA), i.e. applications whose input and output arguments can be expressed as a set of key-value pairs. CEA is an implementation of UWS-PA.SpecificationThe latest version of the UWS proposal is v1.0 and is currently a recommendation. Note from version 0.5 the source of the document is stored in the Volute GoogleCode Project
