Creating a Model

Starting a new model

To create a new model, navigate to the model owner's administration page and click the Add button. For example, with ECA:

1. Go to Administration > Configuration > Workflow > ECA.
2. Click Add ECA model.
3. The modeler opens with an empty canvas.

Empty canvas

A new model starts with no nodes or edges. The canvas shows a clean workspace where you can begin building your workflow.

Setting model metadata

Click the model title in the toolbar to open the Metadata Modal. Here you can set:

Field	Description
Label	The human-readable name for your model.
Description	A text description of what the model does.
Version	Semantic version number (e.g., 1.0.0).
Tags	Labels for organizing and filtering models.
Documentation	A documentation URL for the model.
Executable	Whether the model should be active and executable.
Template	Mark the model as a reusable template.
Changelog	Notes about changes in this version.

Tip

Set the model name and description early -- it helps you identify models in the administration list.

Adding your first event

Every workflow needs at least one event (start node) to define what triggers it. There are two ways to add an event:

Click the + Event button in the toolbar. A popup appears with all available event types. Select one to place it on the canvas.

Building from there

Once you have an event on the canvas, you can build the rest of your workflow:

1. Add actions: Hover over the event and use the quick-add + button.
2. Add conditions: Hover over edges and use the quick-add + button.
3. Configure each component: Click a node to open the Property Panel.
