ModelNamespaces

When a model XML file is used that contains namespaces, the namespaces needed for section model binding, model attribute injection and model node removal need to be specified in the model config.

Syntax

<ModelNamespace
  prefix="..."
  namespace="..."  
/>

Parameters

Parameter	Description	Default	Remark
prefix1	The prefix used to address elements in the specific namespace
namespace1	The namespace as used in the model XML

ModelAttributeInjection

Model attribute injection can be used to inject attributes to the model before generation starts. This is usefull for enriching the model with additional information that is needed during generation. An example of model attribute injection is adding ETL specific datatypes to an attribute or column definition, derived from the database datatype that is already present in the model.

Syntax

<ModelAttributeInjection
  modelXPath="..."
  targetAttribute="..."
  targetValue="..."
  targetXPath="..."
/>

Parameters

Parameter	Description	Default	Remark
modelXPath1	The XPath to apply on the model to get to the element on which to inject the attribute.		See XPath.
targetAttribute1	The name of the attribute to inject.		If the target attribute is already present in the model it's value will be overwritten
targetValue2	The value of the attribute to inject.
targetXPath2	The XPath to apply on the model element to get the target value.		See XPath.

ModelNodeRemoval

Model node removal can be used to remove certain elements or attributes from the model before the generation starts. This can be usefull when the model contains more information then should be used in a certain generation step. For example when a source model is automatically extracted from a source system and you don't want to include certain columns in the extraction process, you can remove these nodes from the model before generating.

Syntax

<ModelNodeRemoval
  modelXPath="..."
/>

Parameters

Parameter	Description	Default	Remark
modelXPath1	The XPath to apply on the model to get to the element or attribute which needs to be removed. When the XPath resolves to multiple elements or attributes, all will be removed.		See XPath.
