A simple example is:
... where you can find "items":
https://www.kozubik.com/items/
... and one thing inside of "items" is an article on NDS emitters:
https://www.kozubik.com/items/nds/
... which contains supporting multimedia objects:
https://www.kozubik.com/items/nds/images/
Not only do you know where you are in the tree, but it is also discoverable: by using index.html default pages and your web servers directory indexing code, you can have a very flexible resource that is easy to navigate.
