Hi again Michael,

Please read the previous email I just sent first.

About sorting by date, I think this is possible by adjusting the
instructions at step 9 of the tutorial
http://wiki.greenstone.org/wiki/gsdoc/tutorial/en/multimedia_collection_build.htm
* Switch to the Design panel and select the Browsing Classifiers section.
* Add an AZCompactList classifier. Select dc.Format as the metadata
field and specify "browse" as the buttonname. Click the sort checkbox,
and select ex.Title in the drop-down list: this will make the classifier
display documents in alphabetical order of title.

While I can't confirm the following at the moment, since I am in the
middle of adjusting some code before I can try out anything, in your
place, I would try
- adding a DateList classifier using the drop-down box near the bottom
of GLI's Design Panel.
- when you press the Add Classifier button, tick the Sort checkbox and
choose to sort on dc.Date. Maybe you need to set the metadata to dc.Date
too, I'm not too sure. Try rebuilding it and see what is best.

Good luck,
Anupama
