Elements in a Lineage Association

You can add specific elements when defining a lineage association rule. You must specify the "from" element and "to" element to identify the "from" and "to" objects in the association. You can also specify a linkExpression element to define the expression that appears in the data lineage diagram when you hover over the "to" object.

You can use the following elements in a lineage association rule:

lineageAssociation: The following table describes the attributes for the lineageAssociation element:

Attributes
Description

ruleName
Required. Name of the rule defined for the specified lineage association.
from: You can add the "from" element within the association element in an association rule or add the "from" element within the lineageAssociation element in a lineage association rule. The "from" element identifies the "from" object in the association. You must also specify the "to" element.

For example, you create the following association rule:

<loadTemplate name="AS400_1" targetModel="AS400" templateSpecVersion="1.0"> <association ruleName="AS400ParentRule" name="ParentAssociation"> <from>FROM_ELEMENT</from> <to>TO_ELEMENT</to> </association>

In this example, the association rule defines associations between "from" objects and "to" objects. The "from" objects come from the FROM_ELEMENT column in the metadata source file. The "to" objects come from the TO_ELEMENT column in the metadata source file.
to: You can add the "to" element within the association element in an association rule or add the "to" element within the lineageAssociation element in a lineage association rule. The "to" element identifies the "to" object in the association. You must also specify the "from" element.
linkExpression: The linkExpression element specifies the expression text that appears in the data lineage diagram when you hover over the "to" object.

For example, you create the following lineage association rule:

<lineageAssociation ruleName="AS400ViewLinkRule"> <linkExpression>LINK_EXPRESSION</linkExpression> <from>FROM_ELEMENT</from> <to>TO_ELEMENT</to> </lineageAssociation>

In this example, the lineage association rule defines lineage associations between source objects in the FROM_ELEMENT column of the metadata source file and target objects in the TO_ELEMENT column of the metadata source file. Text in the LINK_EXPRESSION column appears in the data lineage diagram when you hover over the target objects.
