DVModeler is available up to and including 2.0.x release.We removed it from the trunk recently, because there are no volunteers to support it, and it hasn't been updated for many years now, becoming a liability.
IMHO despite the missing volunteers, the DVModeler should be still included in the trunk since the DataView packages are also there: cayenne\main\core\cayenne-jdk1.4\src\main\java\org\apache\cayenne\dataview\* Ahmed.
