mdm:matchRules element structure

The <mdm:matchRules> element corresponds to the Match Rules tab in the Boomi DataHub page for the model.

<mdm:matchRules> has a child <mdm:matchRule> element representing each of the model’s match rules.

This example shows the high-level structure for an <mdm:matchRules> element that represents a model’s three match rules:

<mdm:matchRules>
   <mdm:matchRule topLevelOperator="AND">
   </mdm:matchRule>
   <mdm:matchRule topLevelOperator="OR">
   </mdm:matchRule>
   <mdm:matchRule topLevelOperator="NOT">
   </mdm:matchRule>
</mdm:matchRules>

The <mdm:matchRules> element’s topLevelOperatorattribute corresponds to Top Level Operator in the Match Rule dialog in Boomi DataHub. The attribute’s valid values are AND, OR, and NOT.

<mdm:matchRule>

An <mdm:matchRule> element represents a match rule in the model and corresponds to an entry in the Match Rules summary list in Boomi DataHub.

This example shows the high-level structure of an <mdm:matchRule> element that represents a match rule having AND as the top-level operator, a simple expression, an advanced expression, and an expression group. The expression group has OR as the operator, a simple expression, and an advanced expression.

<mdm:matchRule topLevelOperator="AND">
   <mdm:simpleExpression>
   </mdm:simpleExpression>
   <mdm:advancedExpression>
   </mdm:advancedExpression>
   <mdm:expressionGroup operator="OR">
      <mdm:simpleExpression>
      </mdm:simpleExpression>
      <mdm:advancedExpression>
      </mdm:advancedExpression>
   </mdm:expressionGroup>
</mdm:matchRule>

<mdm:simpleExpression>

<mdm:simpleExpression> represents a simple (non-advanced) expression in the match rule.

Example:

<mdm:simpleExpression>
   <mdm:fieldUniqueId>NAME</mdm:fieldUniqueId>
</mdm:simpleExpression>

The child <mdm:fieldUniqueId> element corresponds to the selected Match on field in the Match Rule dialog in Boomi DataHub.

<mdm:advancedExpression>

<mdm:advancedExpression> represents an advanced expression in the match rule.

Example:

<mdm:advancedExpression>
   <mdm:ruleOperator>EQUALS</mdm:ruleOperator>
   <mdm:tolerance>0.0</mdm:tolerance>
   <mdm:firstInput>
      <mdm:inputType>INCOMING</mdm:inputType>
      <mdm:fieldUniqueId>NAME</mdm:fieldUniqueId>
   </mdm:firstInput>
   <mdm:secondInput>
      <mdm:inputType>STATIC</mdm:inputType>
      <mdm:value>No Name</mdm:value>
    </mdm:secondInput>
</mdm:advancedExpression>

<mdm:advancedExpression> has child elements, each of which corresponds to a property set in the Configure Advanced Expression dialog in Boomi DataHub:

Element	Corresponds to	Valid content
<mdm:ruleOperator>	Expression	IS_SIMILAR_TO, STRICT_EQUALS, EQUALS
<mdm:similarityAlgorithm> (applicable only if <mdm:ruleOperator> contains IS_SIMILAR_TO)	Use Similarity Algorithm	Jaro-Winkler, Levenshtein, Bigram, Trigram, Soundex
<mdm:tolerance>	Tolerance	decimal value in the range 0.0–1.0, except if <mdm:similarityAlgorithm> contains Soundex, in which the content is an integer in the range 0–4. This element contains 0.0 if <mdm:ruleOperator> does not contain IS_SIMILAR_TO.
<mdm:firstInput>	First Input	see below
<mdm:secondInput>	Second Input	see below

<mdm:firstInput> and <mdm:secondInput> elements have child elements, each of which corresponds to a property set in the Configure Advanced Expression dialog in Boomi DataHub:

Element	Corresponds to	Valid content
<mdm:inputType>	Input Type	EXISTING, INCOMING, STATIC
<mdm:fieldUniqueID>	Model Field	unique field ID (this element is present only if <mdm:inputType> contains EXISTING or INCOMING)
<mdm:value>	Value	static value (this element is present only if <mdm:inputType> contains STATIC)

<mdm:expressionGroup>

<mdm:expressionGroup> represents an expression group in the match rule.

• The element has a child <mdm:simpleExpression> element representing each simple (non-advanced) expression in the expression group and a child <mdm:advancedExpression> element representing each advanced expression in the expression group. These child elements are described previously in this topic. Additionally, <mdm:expressionGroup> has a child <mdm:expressionGroup> representing each nested expression group.

• The <mdm:expressionGroup> element’s operator attribute corresponds to Group Level Operator in the Match Rule dialog in Boomi DataHub. The attribute’s valid values are AND, OR, and NOT.

This example shows the high-level structure for an <mdm:expressionGroup> element that represents an expression group with the OR operator, a simple expression, and an advanced expression:

<mdm:expressionGroup operator="OR">
   <mdm:simpleExpression>
   </mdm:simpleExpression>
   <mdm:advancedExpression>
   </mdm:advancedExpression>
</mdm:expressionGroup>
