fileIndex or privateTypeIndex?

I wanted to create a file index for an app that i am working on which, for now, only stores the type of a file/types contained in a folder. For a folder /private that contains a jpeg file it would be:

[
  a terms:TypeRegistration;
  terms:forClass jpeg:Resource;
  terms:instanceContainer priv:
].

I wanted to save all of the indices in a users pod at /settings/fileIndex.ttl

Does this make sense or should i just use /settings/privateTypeIndex.ttl for this?
Any help is appreciated :+1:

@ludwigschubi hi . It depends if you consider the resources could be shared with other apps or if it’s an app configuration https://github.com/solid/solid/blob/master/proposals/data-discovery.md
