The imported project is a new project and so has no natures.
In order for the QVTr builder
to analyze the source files and add error markers it is necessary to use
Add QVTrelation Nature from the
right button menu of the org.eclipse.gmt.umlx.qvtr.examples
project within Navigator or Package Explorer Views.
In order to view or modify
the (Meta-Model) Registrations it is similarly necessary to use
Add Model Registry Nature.
Open qvtr/qvtr2qvt2/Relation2Core.qvtr.
The contents will be shown highlighted, and since this transformation is work in progress a number of meta-model compliance errors are also shown.
The import statement in Import/spec/UmlToRdbms_1.qvt has been changed to use a string-literal file specification rather than a dot-separated package path. (The current QVTr specification is for a simple identifier.)
Duplication of meta-models has been reduced by moving all meta-models to the root folder of each example.
The DNF example makes use of an unspecified and undefined ID property.
