Entities in Incari, such as Objects, Nodes, Screens etc., each have a set of Attributes. An Attribute defines a specific characteristic of an entity, and thus by modifying the Value of these Attributes you can modify its characteristics.
Generally, Attributes fall into one of two categories:
Object Attributes - Modify the characteristics of Objects and can be edited in the Attribute Editor
Node Attributes - Modify the behavior and characteristics of Nodes and can be edited in the Node Attribute Editor.
