Output Rules and logic for the QU4RTET open-source EPCIS / Level-4 supply chain and trading-partner messaging framework.
Intro
The quartet_output module is responsible for inspecting inbound messages and, based on criteria defined by users, singling out some of those messages for further processing. Once a message has been filtered, it is typically used to create a new message from some existing EPCIS data or to simply create a new message using the same data with the intent of sending that message to another system.
Criteria
The quartet_output module allows users to define EPCIS Output Criteria definitions. These definitions allow users to instruct the module to look at inbound EPCIS events and look for events that meet certain selection criteria. For example, users can define criteria that would inspect all inbound Transaction Events of action ADD from a specific bizLocation with a Purchase Order business transaction attached. Once an event arrives meeting these criteria, the system allows a user to use that event to trigger the generation of a shipping event along with all of the serial numbers for the epcs specified in the triggering event. Other scenarios are possible as well and, of course, users can implement Rules and Steps of their own that do just about anything once an inbound event has been filtered.
Transport
quartet_output allows users to configure transport configurations using both EndPoint and AuthenticationInfo database models. These models are attached to the criteria that filter EPCIS events and allow the user to specify where messages should be sent once an event has been filtered and has triggered any outbound processing logic.

Quickstart
Install quartet_output
pip install quartet_outputAdd it to your INSTALLED_APPS:
INSTALLED_APPS = (
...
'quartet_output.apps.QuartetOutputConfig',
...
)Add quartet_output’s URL patterns:
from quartet_output import urls as quartet_output_urls
urlpatterns = [
...
url(r'^', include(quartet_output_urls)),
...
]Features
Output determination allows you to create filters on inbound EPCIS data and determine which inbound EPCIS events trigger outbound business messaging.
Define HTTP and HTTPS end points for trading partners.
Define various authentication schemes for external end points.
Outbound messages take advantage of the quartet_capture rule engine by creating a new outbound task for every message. This puts every outbound task on the Celery Task Queue- allowing you to scale your outbound messaging to your liking.
