Data Model

The "document" for Treehouse is the Workspace, which is mostly a container for nodes. These nodes are based on a versatile and extensible API and data model called Manifold. In short, nodes:

• have a unique ID
• have a text name
• can be children to other nodes
• can have key-value attributes
• can have components

Most importantly, nodes build a tree-like structure where each node can be extended with components. Components extend the state and functionality of a node. For example, a checkbox component can be added to a node. This gives it a state (checked or not) and allows the UI to render it differently (add a checkbox).
