Hi! vtkdata should be pushed to F-7 updates testing and to rawhide, as it is a requirement for vtk-testing and vtk-examples.
I tried to hardlink the package from FC6 but this wasn't accepted, so I rebuilt it for F7 (but it's the same package) According to what I've been told on f-m-l it will automatically appear in rawhide as well. Thanks for reporting!
