There is a framework that implements some business logic for a niche organization. That project is open source, pushed to gitlab and uses a LGPL v3 licence.
What I want, is to extract the business logic in the form of BPMN diagrams and reimplement everything on a different framework.
I will not be copying/touching that framework, all the code will be mine.
So my question is, will my code be derivative work and can I publish it on any licence I want?
