I don't consider multiple file types/categories a big feature. Suppose a file 
has type/category Audio. This means it belongs to the following categories: 
File, Media, Audio. So it already has multiple types. The question is whether 
we allow these types to be outside of strict hierarchy.

Multiple field inheritance, is too in my opinion is not a big feature request 
if inheritance is implemented as such. It might be useful if we link multiple 
external ontologies. If we stick with a relatively simple core ontology, it 
may not be required. Time will tell.

Source code: It is a text document(contains text) and software(has 
dependencies on other software).
