@johnbeve Should I remove the Test Ontology which I created. Or Can we maintain tests Ontology to validate SPARQL Modifications in deployment folder going forward.

@shanmukhkalasamudram We should keep them and organize them so others can run the tests themselves. Would you mind creating a README for that repository, and we'll plan to put the toy ontologies we use to test queries in such a repo.

Should we maintain a new repository altogether for this test? Or maintain in the same test folder and update the readme of common core repo. @johnbeve
