Value Reference Mapping
Defines alias for mapping path which can be used in mapped name and required attributes in element mapping section, we will use this to reduce duplicated mappings. This will contain two kinds of paths:
Path No. 01: Element which holds a reference to the current element, as follows:
<Specific_item_classification uid="uid">
<Associated_item>ref_uid</Associated_item>
<Classification_name>assembly</Classification_name>
</Specific_item_classification>
<Item uid="ref_uid">
</Item>
Path No. 2: Element which is referenced by current element, as follows:
<Document_file uid="uid">
<File_format>ref_uid</File_format>
</Document_file>
<Document_format_property uid="ref_uid">
<Data_format>ApplicationData</Data_format>
</Document_format_property>

mapped_name
Attribute
String
No

type
Attribute
String
No
For Path No. 1: The relative path to check if current element is a supported Windchill tag. for example, Item_shape will also be used to represent representation and EPMDescribeLink .
For Path No .2: The element name which will be create as reference, this should be sub element.
ref_attribute
Attribute
String
No
The relative path which keeps the object reference, used for Path No. 1 only.
connect_reference

String
No
The sub element which will be used as reference.
multiple_instances
Attribute
String
No
To maintain the multiple instances of the describe elements (i.e. that has ‘mapped_name’ and ‘ref_attribute’) associated with root element or current element. This is needed when the root element has no direct link with the described element.
reuse
Attribute
Boolean
No
Defines if this element is reusable, work with locate_by attribute together to find previous created element instead of create new one all the time.
locate_by
Attribute
String
No
Defines the attribute list of a reusable element, separated by a comma (,).
ref_type
Attribute
String
No
The element name which will be create as reference, this should be root element, used for Path No. 2 only.
required_attributes
Attribute
String
No
Attributes which are required for current element, separated by a comma (,).It can be relative path and alias path.
attribute_name
Attribute
String
No
The relative path which will be used to hold reference or attribute value, used for Path No. 2 only. If identifier is configured, it will be used to store the name of attribute.
identifier
Attribute
String
No
The relative path which will be used to hold attribute value, works with attribute_name together to store attribute name and value.
Separator
Attribute
String
No
Splits the value associated with this attribute based on the given separator value. Assigns each part of this value to the various sections as specified in the path Attribute.

connect_reference

parent_reference_attribute
attribute
string
No
The attribute is created to cater very special condition. when the current element unable to identify the correct root element. The attribute is used to identify the intermediates objects from the parent element. The intermediate object is then compared with the ‘name’ object.
Example: Next_assembly_usage_occurence is linked to product_deifnitions and Transformation is linked with shape_representation of the products. While import to compare the correct shape representation, one has to traverse from instance product_definition to shape_representation.
Tips
Use the following pattern to define value attribute:
{ROOT}/usedBy/ObjectReference/ufid, this means to get the value of attribute named usedBy/ObjectReference/ufid from the current element.
