@matthieubosquet @langsamu I have noticed that the Solid shape for person uses vcard:email vcard:phone whereas @solid/object uses vcard:hasEmail and vcard:hasTelephone. owl:equivalentProperty maps the properties in vcard, but do you want to choose one property in solid/object? If standardise on vcard:hasEmail, then the Person shape will need to be changed in https://github.com/solid/shape-generation-artefacts/tree/main/shapes/Person and it will no longer be a shape 'as used in Solid OS'.
