Tool specifics explanation

I’m working for a company that’s in search of a tool for managing semantic models for optimizing the structure of their database.
I have made a rough sketch of tools that can be used for this, where we also listed Stardog because of an initial market research I performed.

After presenting this list to the company, I have received a list of additional requirements that the tool must support.

I’ve listed these requirements below. Would someone be willing to take the time to help me out and tell me in what degree Stardog supports these requirements?

Thank you in advance!
