A CLI tool that tries to convert simple OWL ontologies into SHACL shapes. OWL ontologies define logical relationships. SHACL shapes define a data scheme, and allow to validate data against them. Strictly speaking, as these are different things, such a conversion is thus illegal/wrong in the ideological/theoretical sense. Thus this tool is not generally applicable, but only under the circumstance, that the OWL ontology is actually written as a data specification - if it is understood as a kind of distributed database schema, rather then for logical inference. Not only that, but it also has to conform to certain, very narrow rules, and only a few basic properties are translated into SHACL; the rest is ignored.
