Rewriting the notebook's filesystem

[Kyle Brooks]

As far as I can tell, the only non-hack solution to the problem of implementing

folders and links in the sage notebook is to rewrite the entire filesystem 

to replace the current "home/user/<id_number>" representation and toward 

a more robust "home/user/<path>" system. This would be backwards-compatible

with the old system, because a user's existing worksheets would just have the 

new "path" variable set to their old id_number. Links would work because the 

creator of a group of worksheets would be able to predict a worksheet's 

filename.

The first step I'm going to take is to rewrite the system to work with strings

(filenames) instead of id numbers (ints). When that is done I will start 

implementing folders. 

Does anyone have any suggestions or other input?

You might just try to go with paths right off the bat. Flask can get an
entire path using something like in the example here:

It's documented here:
