<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010>Will users be
notified about changes to files, atomic-datasets or realm-datasets? I
think Gavin has said in the past that users will be emailed when *files*
change. Consider the scenario:</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=009573911-26022010></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 1. A
realm-dataset DS1 is published at version v1.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 2. User A
downloads variable V1 from DS1.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 3. User B
downloads all of DS1.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 4. An error is
found in variable V2 of DS1.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 5. The files
for V2 are replaced and DS1 is republished as version v2.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 6. User B is
notified that some files have changed in DS1.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 7. User A is
*not* notified because he never downloaded the files that
changed.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=009573911-26022010> 8. User A
& B collaborate discussing the data from DS1 v1. THEY HAVE DIFFERENT
FILES!</SPAN></FONT></DIV>

system is supposed to work it's going to be very
confusing.</SPAN></FONT></DIV>
