Re: ANN: django-kolibri - a concept for Asynchronous Processors/Workflow management for django.

I only got as far as reading the project overview, but it looks incredibly sweet. Will have to give it a try over the weekend.

Keep up the good work!


Sincerely,
André Terra

Yes, it might be a good idea to put that in the beginning of the info.

Well, each time a processor is executed it creates a record in the
database, with a link to the item it processed. The current system
will show if some processor has been used on a given model instance
before, but nothing is stopping you from processing that instance
again. Perhaps the processor could have some extra property saying if
it should only be executed once for any given item? A possible 0.2.0
feature :-).

Thanks for your interest :-)
