Re: pySHACL Question

I just answered an old but similar question on StackOverflow: https://stackoverflow.com/questions/53108262/shacl-sparql-targets-not-giving-correct-inference-while-using-pyshacl/60969316#60969316 <https://stackoverflow.com/questions/53108262/shacl-sparql-targets-not-giving-correct-inference-while-using-pyshacl/60969316#60969316>

Better to ask there as the answers are public.

Even whiteout human-redable error messages, you should be able to manually inspect the focus nodes (d:e4, d:e3 & d:e2) and see if you can determine whether they are should be failing. For example, it looks like d:e2 is missing 1+ hr:jobGrade.
