**Table 5** LabelAttributeValue¶
Parameter	Mandatory	Type	Description
id	No	String	Label attribute value ID.
value	No	String	Label attribute value.

**Table 6** LabelProperty¶
Parameter	Mandatory	Type	Description
@modelarts:color	No	String	Default attribute: Label color, which is a hexadecimal code of the color. By default, this parameter is left blank. Example: #FFFFF0.

@modelarts:from_type	No	String	Default attribute: Type of the head entity in the triplet relationship label. This attribute must be specified when a relationship label is created. This parameter is used only for the text triplet dataset.
@modelarts:rename_to	No	String	Default attribute: The new name of the label.
@modelarts:shortcut	No	String	Default attribute: Label shortcut key. By default, this parameter is left blank. For example: D.
@modelarts:to_type	No	String	Default attribute: Type of the tail entity in the triplet relationship label. This attribute must be specified when a relationship label is created. This parameter is used only for the text triplet dataset.
