here is my scenario. I have a pre-defined data type structure for books. Just take it as an example for the sake of simplicity. The structure looks like the image below. It's a Labeled Property Graph and the information is self-explained. This data type structure is fixed, I cannot change it. I just use it.

The problem of this design is: we don't know which information belong to which book. For example, we cannot distinguish the
My question is: how to solve or avoid this problem? Should I create 1
MandatoryData for each book? Could you propose me any design?
