Creating a up reverse node reference list of a node in Drupal 7

What we are trying to do in Drupal 7: create a block that can be attached to a node view or taxonomy term view. In this block, a user can add links. These links can point to contacts, documents, links to other websites or taxonomy terms. In the back-end, a user can select a contact, document or link. The user then gets 开发者_如何学运维a list of all nodes where this link is used. If the link is changed, it is updated in all the nodes where it is used.

In other words, a node reference that works in both directions, for multiple nodes. Any ideas are mightily appreciated :)

Hi have you tried to use Corresponding node references module? http://drupal.org/project/cnr

You can use: http://drupal.org/project/content_dependency

It works for both node reference & entity reference modules automatically.
