Cognos Transformer and verb MDL

There are two types of Model Definition Language: verb MDL and structured MDL. Both types can be used to completely define a Cognos® Transformer model. However, by default, Cognos Transformer generates models in structured format, the original version of MDL. This helps to ensure compatibility between models created in different versions of Cognos Transformer.

Use verb MDL when you want to make changes to an existing model, but first you must add the following line to the cogtr.xml file:

<Preference Name="VerbOutput" Value="1"/>

Setting this parameter only affects the format of model definitions subsequently generated and saved by Cognos Transformer. Regardless of this setting, you can still use both verb and structured format on any output file.
