I am going to try my best to explain what I am working on; sorry if this does not come out comprehensable.

The main tables:

Part
Feature
Attribute

The join tables:

FeatureAttribute {many-to-many join table between Feature and Attribute, with no additional data attributes}
ConfiguredFeature {many-to-many table between FeatureAttribute and Part, with additional data attributes}

The model:
A Feature can have many Attributes, likewise an Attribute can be used within many Features (many-to-many). A Part can have many FeatureAttributes assigned to it with additional information (value, granted). This is the ConfiguredFeature table.

I did not create a mapped class for FeatureAttribute because there was no additional data required. This is mapped in Feature.hbm.xml as follows:



My question is how do I map ConfiguredFeature to Part, or am I way off. Basically I want to assign a value to the Attribute only when it is assigned to a Part.

I was just wondering if there is anything I could add that might clear up the question.
