How far does the Non Commercial aspect of by-nc-sa stretch?
E.g. someone published a JSON Schema for an (external to both of us) set of JSON files that I wish to validate without a license. I asked them if they could license it so I could use it in a free/open tool that allows people to create and validate that their game-resources are valid according to the Schema.
Whilst I never want to take my tool commercial or closed, I can't say the same thing about the assets produced by the tool, which indirectly uses the CC - NonCommercial license via the published JSON Schema, which could be hosted on sites with ad-revenue or otherwise used for profit.
Will my tool using the NC JSON Schema force my users to use their creations only in a NC way?
If I make no modification to the JSON Schema in my tool, does my tool also have to be published under by-nc-sa ?
