[Using Sakai] File type for uploaded files

[Norman Danner]

I have one general question:  how do I assign default file types for 
files that I upload to Sakai?

More specifically, here are two cases that have come up recently.

Occasionally I upload a PDF file, and it is marked with a file type of 
application/binary.  This doesn't happen with all PDF files.  Certainly 
all of them have filenames of the form XXX.pdf.

Even more annoying (and special-case) is that I upload SML (Standard ML) 
source code files, and those are assigned type application/binary. 
Obviously these are not standard files, but I'd like them to default to 
text/plain.

Of course, I can set the file type manually after uploading by editing 
the file details, but that is a real pain.  And apparently that data 
isn't preserved with the file; if I upload a new version of the file, I 
have to manually set the file type again.

Can setting default file types by filename extension be done via Sakai 
properties?  Is it something I have to configure in Tomcat?  Something else?
