Initial implementation for Governance Workflows

[IceS2]

Initial Governance Workflows Implementation

The initial implementation focuses on the foundation to build customizable workflows:

• It defines the JSONSchema for Workflow Definition, Instance and Instance State
• It defines the JSONSchema for the Workflow Elements (Nodes, Edges and Triggers)
• Creates the needed Migrations for using Flowable and for te Workflow Entities.
• Creates the needed Endpoints
• Migrates and updates the Glossary Approval Workflow
• Creates the first iteration of the Table Certification Workflow

Workflow Entities

Workflow Definition

Defines a Workflow. It is composed of Nodes, Edges and ONE Trigger

Workflow Instance (Time Series)

It contains all the Workflow Runs (Instances)

Workflow Instance State (Time Series)

It contains all the Workflow States for each instance.

---

Workflow Elements

Edges

Connects two different Nodes. It could contain a condition that branches the flow.

Nodes

• Start Event
  Start of the Workflow

• End Event
  End of the Workflow

• User Approval Task
  Node that creates a User Task for Approval.
  It will be iterated upon once we refactor tasks and have Task Templates.

• Check Entity Attributes
  Node that allows the user to automatically check for different conditions on the Entity Attributes.

• Set Entity Certification
  Sets an Entity Certification attribute.

• Set Glossary Term Status
  Sets a Glossary Term Status.

Triggers

Configuration needed to actually start the Workflow.

• Event Based Entity Trigger
  Listens to Create and/or Update events for a given Entity Type.

• Periodic Batch Entity Trygger
  Runs on a given schedule for a given Entity Type.
