It's been a long time since I've been able to work on the core of Umbraco version 4 as it's been extremely busy here. I've been meaning to post this document up for some time but just never got around it. Some umbracians were asking about trees in version 4:

http://forum.umbraco.org/yaf_postst5259_Fun-with-Trees--New-patch-released.aspx

I've attached the file that describes the version 4 tree api. This was an initial document created for the Umbraco core team. It is probably close to 100% accurate but i know there's been some minor changes to the tree api since i wrote this.

Hope this helps some of you!

Launched in November 2008 the new Sunbeam.com.au site allows users to find products through multiple navigation paths thanks to a unique tagging system that allows products to be related on any number of levels. Products are also related to recipes and tips and tricks for consumers to make the most of their products.

With high investment in IA the user can choose from two paths "I Know What I Want" for those searching for something particular, and "I'd Like To Browse" which allows the user to browse products by room and further still, by a selection of lifestyle choices for example the food lover who makes meals from scratch or those looking for quick and easy food preparation. 

At the product level not only are images, manual downloads and for featured products, a 360 degree photographic view available but the unique tagging system pulls related products (such as accessories) and similar products that can be compared by the 'comparison tool' - allowing the user to see product information displayed together for easy evaulation.
