In my opinion, the issue is that it is not clear to me what you are asking about. There appears to be a lot of jargon (framework, domain, class diagram) whose meaning is not clear to others. I think this mm is making it difficult for people to figure out what you are asking.
The SE system is different than other online communities. Please take a look at our help center. What the comments were trying to do is guide you to provide information that people think might help clarify your question. They may not be the right questions to ask, but there is something unclear about your question.
Instead of being highly abstract in the question, you might want to try and provide more specifics. Instead of assuming the terminology is known, provide links or references to the key concepts, or better yet descriptions/definitions.
