Name: aidr-trainer-pybossa



The aidr-trainer-pybossa, also known as the PyBossa Scheduler is responsible for exchanging items from the task buffer to and from our PyBossa installation, named MicroMappers.

It operates periodically by:

  1. Checking if there are items waiting to be labelled in the task buffer.
  2. Marking those items as assigned to MicroMappers
  3. Send those items from AIDR to MicroMappers
  4. Checking periodically in MicroMappers if there are new labelled items
  5. Send those items from MicroMappers to AIDR
