Some of the DCMI folks developed a test engine that includes some test 


Select an engine (those are the tabs across the top), then "2. 
constraints" and at the bottom there are some constraint examples you 
can select. Select "3.data" and you see some data examples for those 
constraints. None of these use SHACL, of course, but I suspect it might 
not be hard to modify them.

If these look at all useful, I am willing to turn out more test records 
of the same type.


And I am sure I have left silly bugs in this short amount of
