<br><font size=2 face="sans-serif">Maybe the last accessed requirement
could be more efficiently satisfied by a simple tagging mechanism? If an
asset gets marked during the 6 month interval then it has been used at
least once, and should be retained. If not then it might be lifted to a
second level of asset storage. If the marking was done asynchronously with
respect to normal asset operations, perhaps by a low-priorty region module
that examined the current cache, then there would not need to be any real
performance impact. I would definitely suggest that the last accessed info
NOT be stored with the assets as metadata, it seems more sensible to store
it in a separate table.</font>
<br>
<br><font size=2 face="sans-serif">How much is this worth if we move toward
an environment built around an effective asset server model? The same might
be said about e-mail and agent servers, but I suspect the cost of adding
the field is pretty trivial. Where was the week-end discussion? I didn't
see it in this mailing list.</font>

<br><tt><font size=2>I've got a couple of proposed db fields that I think
we should add in,<br>
but I want feedback before just putting it in.<br>
<br>
users:<br>
* email - this is added by a lot of the web based management stacks,<br>
and would be really handy to be in the base user definition. I suspect<br>
this is non controversial.<br>
<br>
assets:<br>
* create_time - the unix timestamp when the asset is created<br>
* access_time - the unix timestamp for last asset access<br>
<br>
The rationale for these asset additional fields was some brainstorming<br>
this weekend on how we'd ever support asset reaping. Why not perfect,<br>
this may help in determining what are active assets, and what are<br>
ancient assets that may be suitable for reaping. Without these bits
of<br>
information, we've got a hard time here.<br>
<br>
Comments welcomed,<br>
