Workflow Services (Back End for Workflows and More)

Backend for Workflow app, To-Do app and other features that need scheduling (e.g. patron status change when expired, loan status change after shelving period) and automation.

WFE consistes of several components, namely:

Scheduler a stand-alone component in FOLIO that can be configured to trigger operations with a specified schedule or frequency.

Workflow templating a component that provides a way to define a series of operation (with conditionals) in a form of machine-readable template (most likely JSON).

State-machine a component that provides automation through execution of several operations in sequence and ability to perform decision logic at transition points. It includes the ability to notify and wait when human intervention is required.

Email and message formatter allows to format and send notification in form of e-mails.

Message queue a new facility in Okapi that allows for publish/subscribe style of operation chaining rather than direct, module-to-module message routing.
