# Intrinsic Attributes

A few attributes are intrinsic. Aliases have their own values of intrinsic attributes. Intrinsic attributes are never inherited from prototypes.

Intrinsic attributes concern properties of the alias that are necessarily distinct from the original. For example, moving an alias does not move the original note, so $Xpos and $Ypos are intrinsic. Other intrinsic attributes include $Height, Width, $ID, $Container, $Created, $Modified, $Creator, $RuleDisabled, $DisplayExpressionDisabled, $IsPrototype, $MapScrollX, $MapScrollY, $TimelineBand,and $AgentPriority.

A number of read-only attributes are intrinsic because their value may differ from the value of the original. These include $OutlineOrder, $OutlineDepth, $SiblingOrder, $InboundLinkCount, $OutboundLinkCount, $WebLinkCount, $TextLinkCount, and $PlainLinkCount.

In expressions and actions, an alias refer to the intrinsic attributes of its original note using the designator `original`. For example, if `this` note is an alias, `$Height` refers to the position of the alias and `$Height(original)` refers to the height of the original.
