Documenting issues with SHACL and variations in SHACL output.

• /ontologies/: a folder for each ontology referenced in the repo; folder should also contain all of the dependencies for the ontology
• /scripts/: supplementary tools for interacting with ontologies and other parts of the repo:
  • ./scripts/update_ontologies.sh: run this to update the local cache of all ontologies
• /testcases/: contains folders, each with a different SHACL validation or inference scenario:
  • each testcase has 2 files: data.ttl containing data to be run through inference or validation, and shapes.ttl containing the SHACL shapes to perform that inference or validation

There are two implementations available:

• https://github.com/RDFLib/pySHACL
• https://github.com/TopQuadrant/shacl

These are abstracted behind simple Python wrappers in the testshacl package in this repo

Use poetry to run either the pyshacl or topquadrant_shacl script on a testcase directory:

• poetry run pyshacl testcases/sh_or_ambiguity
• poetry run topquadrant_shacl testcases/sh_or_ambiguity
