We can completely rebuild the whole database for version 2 and we should do so.
I already set up an account at Vertabelo where we can work on the scheme all together. Please contact me to get an invitation (needed for edits).
Keep in mind that the Eloquent ORM should be used. Don’t overspecify all the things here, but keep the conventions from Eloquent in mind.
Also, the scheme is not public viewable.
