Drupal Rules - Reference

I need to creat开发者_如何学JAVAe something like this. Have several nodes ( NODE A ) with: C++, PHP, PLSQL, JAVA, etc... ( in each node )

And for, each one of these nodes i will have something like (NODE B): 1 - medium skills; 2 - good skills; 3 - guru;

I have a reference field in (NODE B) to (NODE A) but i have always to create the same reference data for each node that i create.

Ive tried to use Rules, i did no get to reach to an good solution.

Thankyou all in advance.

PS: this kind of reference has to be like this because i'm using Hierachical Select!

I am not quite sure, but I think that you may find that you could use a taxonomy instead of node reference. Which would be much easier.
