Node Attributes
The Attribute tab of the Node
Properties is used to specify the attributes of a node. Each Attribute
consists of an Attribute Name and an Attribute Description. The
attribute name (or attribute identifier) is a unique name to identify an
attribute. Node attribute name can only consists of C like identifier
characters and must not start with HR_ since the Hugin Graphical User Interface
uses
attributes starting with HR_. Attribute description consists of a
string which can be used to give a more detailed description of the node. It is
possible to modify, delete, add attribute both in edit
mode and Run Mode.

Attributes are useful in situations where you want to store additional information (knowledge) in the network apart from cause effect relations. This feature can be very useful when using the Hugin API and can save a lot of programming.
