 ⚠️ At the moment, this code is VERY work-in-progress!
 
 DTS validator is a suite of tests to validate implementations of the [DTS API](https://w3id.org/dts).  The tests are implemented with `pytest` and the `pytest-html` plugin is used to generate an HTML report of the performed tests. For now, only JSON validation (against JSON schemas) is implemented; JSON-LD validation (against SHACL shapes) will be added later one.
