Current Behaviour:

Expected Behaviour:

running pyshacl from the command results in this

(kglab) ➜  validation git:(master) ✗ pyshacl -s shapes/oih_checkDownload.ttl  -f human ./datagraphs/lipd.json
Validation Report
Conforms: False
Results (1):
Constraint Violation in MinCountConstraintComponent (http://www.w3.org/ns/shacl#MinCountConstraintComponent):

        Result Path: [ shacl:inversePath rdf:type ]
        Message: Less than 1 values on :Course->[ shacl:inversePath rdf:type ]

but the script simpleshacl.py in https://github.com/gleanerio/notebooks/tree/master/notebooks/validation when run generates

Good catch, thank you @fils !

I had an exchange with the lead for pySHACL yesterday. They'd had an error in their requirements.txt file that caused an installation conflict, even though they were trying to upgrade to support RDFlib v6.x

I work with the upgrades since that issue is resolved, and see if the version bumps resolve this

@ceteri I'm still seeing this error after the update.

Traceback (most recent call last):
  File "/home/fils/.conda/envs/kglab/lib/python3.8/site-packages/rdflib/plugins/parsers/notation3.py", line 1174, in uri_ref2
    ns = self._bindings[pfx]
KeyError: 'rdf'

I can try and dive into it tomorrow. I have to leave today for family. I really want this one working since this pattern check is turning out to be really useful for my use cases. So I am motivated.
