When creating your own Blueriq as a Service (BaaS), it is possible to include a justification tree in your response to the caller of the webservice. This tree explains how a certain attribute was derived by the inference engine.
To do this, you need the Custom Schema Element: AQ_JustificationTree, which is part of the BlueriqBasicModelling Library. If you open this schema element, you find under the 'XSD' tab the following XSD:
<?xml version="1.0" encoding="utf-8"?> <xs:schema targetNamespace="http://aquima.com/schemas/justificationTree/1.0" xmlns="http://aquima.com/schemas/justificationTree/1.0" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="justificationTree"> <xs:complexType> <xs:sequence> <xs:element ref="attribute" minOccurs="1" maxOccurs="1"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="attribute" type="attributeType"/> <xs:complexType name="attributeType"> <xs:sequence> <xs:element name="value" minOccurs="0" maxOccurs="unbounded" type="xs:string"/> <xs:element name="justification" minOccurs="0" maxOccurs="1" type="xs:string"/> <xs:element ref="attribute" minOccurs="0" maxOccurs="unbounded"/> </xs:sequence> </xs:complexType> </xs:schema>
You need to make this XSD part of the response of your BaaS. The easiest way is to save the justification XSD in a separate file and use the <import> statement in your own XSD. After importing your WSDL/XSD with the justification tree in it, go to the Schema Set Editor and open the justification tree element.
You have to make the justification XSD really part of your own WSDL/XSD. This means referring to it with an <import> statement and supplying this file together with your own WSDL during the import.
You will see the following window:
- Choose AQ_JustificationTree. If it is not in the list, there is probably something wrong with the namespaces in your XSD.
- Choose the name of the entity of which you want to justify an attribute
- The attribute you want to justify.
- If you want to use a different asset format, you can specify this here. The default is 'Text'.
The context of the justification is the WSDL module. This means that no justification is given when using a data-mapping, as the value is not derived with logic, but the value is set by the mapping. To solve this, you can (1) work with only 1 module without datamapping; this can get messy with complicated WSDLs/applications; or (2) duplicate the logic in your WSDL module; by placing the logic in a parent module both modules can inherit from it.
