I'm interested in a system that basically, provide tags organized in categories and subcategories (and, why not, sub-subcategories).
Something like:
SMARTPHONE (category)
Apple iPhone (subcategory)
Apple iPhone 3G (tag)
Apple iPhone 3Gs (tag)
Apple iPhone 4G (tag)
I was interested to use the drupal taxonomy system to do this. I'm working with a custom cms, zend-based.
What do you suggest me to do? Do you think i can somehow extract something useful from the drupal taxonomy or should i do it all myself? Or maybe there simply is a zend class (i don't know) that does all this?
Thank you a lot =)
