[Sugar-devel] [DESIGN] Name object on Activity exit revisited

[Tony Anderson]

Hi, Dave

If, for example, I download War and Peace from Gutenberg to an XO, it 
will take storage space in the Journal. The space taken by this object 
should be
shared among all users. However, a Write document should be private to 
the author. So the mechanism is the same. The datastore class should be 
able to
handle two instances of a datastore - one in /usr/share/  and one in 
/home/username/.sugar/default/datastore. Browse makes this relatively 
easy by recording the source URL in the Journal metadata for the object.
