This rule is used to create a relationship between a tag and a constant value. The constant value is applied to all the tags present in a pdf file. You can define a TagConstant rule by annotating anywhere in the template file.
For example: RT=TC|TNS=Unit|Attr=A1
Here,
-
TC stands for TagConstant which is associated to Attr(Property Attribute)A1.
-
TNS stands for Tag Naming System which defines TagConstant type.
To update the TagConstant rule, use the following steps:
-
Click Configure Rule
to open the Editing Rule for <Rule Name> window.
-
In the Editing Rule for <Rule Name> window, select the property to store the extracted value from the Related Attribute list. For example, Unit is the related attribute.
-
Type the name of the attribute in the Value box. The extracted property is related to this attribute (Attr), and click Ok.
