Monitoring: Progress Information
EXAMINE allows to ask for the completion of:
- an invocation: DONE, NOT_DONE, PARTIAL, ERROR
EXAMINE allows to ask for the progress of:
- a result attribute: returns current accuracy
- an invocation: returns current progress
Progress information is optional, not provided by every megamodule.
==> partial and progressive extraction
==> rescheduling of invocations, stopping slow invocations
==> getting preliminary results which influence program flow (e.g. invocation parameters)
