I would like to suggest the implementation of a naming convention patterns for saving in incremented saves. 

A convention could be MODELNAME-YYYY-MM-DD-HR-MI-SE-YYYY-MM-DD-HR-MI-SE-XXXX.xmi 

MODELNAME = the name of your model (User selectable).

YYYY = Year of creation

MM = Month of creation

DD = The day of creation

HR = The hour of creation

MI = The minute of creation

SE = The second of creation

YYYY = The year of alteration

MM = Month of alteration

DD = The day of alteration

HR = The hour of alteration

MI = The minute of alteration

SE = The second of alteration

XXXXXXXX.xmi = The X'es, a zero padded number incrementing with one for each save that is made i.e. a change counter.

Everything except MODELNAME is generated - The fist time all of the data except the MODELNAME - every subsequent save only the altered data i.e. you have a file name pointing both to the original starting point as well as a pointer to the present state of the model and when it last was accessed and how many times it has been saved, all in plain text in human readable form.

This would be perfect for students not ready to implement big versioning systems for minor projects but who still could benefit greatly from a string of backups.

This would be a perfect feature in conjunction with automated FTP uploads.
