You say you don't see a need for a database?

Definition of a database is: A database is a collection of information that is organized so that it can easily be accessed, managed, and updated.

Sounds exactly like what you're asking for? Consistent organisation of file structure. Unfortunately just saying "Just label the folders correctly." has never been a good way of achieving what you're asking for. Under the current setup it's been proved practically impossible to bring all content creators inline to a consistent folder naming convention across all stores and content. And not just in DS content.

.... ZOMG

Here's a simple example of one of the issues, I have made an eye material that works on both Genesis 3 Male and Female. Lets call it sweet shine eye material. Where is the correct place to put the folder for the eye material preset? It's just a single mat preset in a folder called Sweet Eye Shine.
