Hi Xiping,
The dates serve slightly different purposes:
* dc.date.accessioned = the date/time that DSpace received this document
(i.e. date/time the item was created in DSpace)
* dc.date.available = the date/time that the item was made *available*
through the DSpace web interface.
If you are not using approval workflows, then dc.date.available will
always be the same as dc.date.accessioned.
However, if an item undergoes an approval process, then
dc.date.accessioned will be the date that the approval *began* (i.e.
when the item was created) and dc.date.available will be the date that
the approval *completed* (i.e. when the item was fully approved and made
available to users).

Hello all,
We are in the process of cleaning up our ETD metadata and we came
across something very interesting:
Some of our ETD records have two dc.date.accessioned and
dc.date.available fields and they are very close to each other. For
example:
dc.date.accessioned 2012-01-10T15:05:49Z
dc.date.accessioned 2012-01-10T15:05:50Z
dc.date.available 2012-01-10T15:05:49Z
dc.date.available 2012-01-10T15:05:50Z
My understanding is that every time DSpace accepts a new submission it
gives a time stamp on it. So how come it has two almost duplicate fields.
Thank you.
Xiping
