  Directories are files, indeed. Read-only files. Sometimes with special
alignment rules for the reader, but they are files. I can say nothing 
about other metadata, because I was speaking about generic usecase. And other
metadata is "other". But you are right sometimes it can fit into a different
model, but it is up to an implementation to chose one. 

Thanks,
