Implement DeepZoom Programatically

Hi,
I am looking to build a deepzoom centric application that works exactly like
the hardrock cafe app.
<http://memorabilia.hardrock.com/>

I need to be able to filter a total set of images to eg. just show maps or
letters or photos then sub fitler eg by date etc.

All i could find on the net was the deep zoom composer but that does not
allow me to tag images with attributes and filter as seen in the hardrock
site.

could someone please advise or redirect me to an appropriate forum.

Thanks,
Shaun
