Pythonic transformation from XMI to OpenAPI/Swagger

Goal: As an interface controller I need to transform a given XMI file (XML dialect for UML) into an OpenAPI or Swagger definition (JSON) file. Use cases: Forward engineer RESTful service Export data structures for use in messages See following already existing tools based on Java and EMF: [login to view URL] And see this pythonic approach which does one direction to PlanUML [login to view URL] Provide a similar tool + Coding conventions + Implementation shall be done with Python + For reading of uml data the pyecore library shall be used + It provides out-of-the-box functionality for creating, manipulating, and exporting uml models + For writing the json jinja2 library shall be used + Source code shall be stored under src/ + e.g. src/[login to view URL] + Input and output data shall be stored under data/ + e.g. data/[login to view URL], data/[login to view URL] + [login to view URL] shall contain all necessary python libraries so that in a fresh python environment one only has to do pip install -r [login to view URL] + Acceptance criteria + Source code shall be unit tested under tests/ + e.g. tests/[login to view URL] + Source code shall be tested with an example + Use data/[login to view URL] as input from UML tool + The output json shall be equal to [login to view URL] + If we are not happy with [login to view URL] then we can change it to our needs + The code shall be generic + Principally it shall be possible to also transform any other xmi file following our tbd rules + The resulting json file shall be like data/[login to view URL] + xmi:id values can vary since these must be generated e.g. as uuid + References must be valid + Some attributes like type, association, memberEnd, and navigableOwnedEnd reference other elements using their xmi:id
