This module has a generic name, but it provides one utility function for website administrators: it can undo the 'multiple hierarchy' structure of a vocabulary, by cloning all terms with multiple parents, into multiple terms, each having one parent.
As an example:
Say you have a vocabulary consisting of cars;
...and a content editor on your site wants to add 'white' to both car brands... and decides to be quick by adding one term called "white", with two parents.
This has the following effects:
- You lose the ability to rearrange terms using drag and drop on the 'list terms' page;
- The several 'white's you see in the list cannot have different properties - since they are actually the same term.
Also, if the vocabulary has a lot of terms with equal names, there is no good way to see which exact term has multiple parents.
This module gives you a simple admin screen showing which terms have multple parents, and an option to split the one 'white' term that appears in two places, into two separate 'white' terms.
