Pythonic converter from OpenAPI/Swagger to XMI/XML -- 2

Goal: As an interface controller I need to transform a given OpenAPI or Swagger definition (JSON) into an XMI file (XML dialect for UML). Use cases: Reverse engineer RESTful service Import data structures used in messages See following already existing tools based on Java and EMF: [login to view URL] [login to view URL] [login to view URL] Provide a similar tool using Python and e.g. pyecore (pythonic EMF implementation, [login to view URL]) as well as jinja2 (template engine for transformations).
