python - 如何在owlready2中以编程方式创建类？

Question

我想做同样的事情

with onto:
    class Drug(Thing):
        pass

但有类名

className = "Drug"

怎么做？

我已经用 protege 创建了本体，现在希望它打开，添加一些类并保存回来。我在很多方面都失败了。例如代码

from owlready2 import *
import types

ontology_name = "http://www.semanticweb.org/dimskraft/ontologies/2020/4/my"
file_name = "data/my.owl"
prefix = "file:///home/dimskraft/design/my_ontology/"

onto = get_ontology(prefix + file_name).load()

NewClass = types.new_class("NewClassName", (Thing,), kwds={"namespace": onto})


class Drug(Thing):
    namespace = onto


onto.save(file=file_name, format="rdfxml")

给出以下错误

TypeError: __new__() got an unexpected keyword argument 'namespace'
