Best photo library organizer?

Question

I am looking to get a program for my mac that will store and organize thousands of photos. But it can not be a general photo storer like iPhoto, it must be a very specific organizer that can create layer upon layer of specific categories. As a digital artist, I have a lot of reference photos for drawing, but I need a program in which I can section off and store specific things. For example, it would need to be like this:
Vehicles -v
... planes -v
........ military -v
.............U.S.

I just need a program that will act as a library that I modify into different levels of specifics.

Thank you for any suggestions.
