Best approach to create a new Classification programmatically

Hi there,

Could anybody tell me how I must to go on, when I want to create a new classification programmatically?

In my opinion I must to do the following:

• Create new ClassificationClass

• Assign the ClassificationClass to a category

• Adding ClassificationAttribute

• Adding ClassificationAttributeValues to the ClassificationAttributes

• Adding specific product features to the product model

I'm little bit confused with the relation between the product, classification and product features... It will be nice if someone could explain me shortly, how this stuff really work together...

Many thanks!
