Following the API we have been able to make solid use of both the Search and Audit functions in Navigator.  One thing that has occured recently is we are about to start tagging files in our cluster and while the API is quite clear on the approach, one thing that the API specifically mentions is using the API to update (business) metadata in bulk is not recommended.

I have scoured the web and our resources, and no one appears to know:

What is the recommended method to do a bulk metadata/tagging update in Navigator?

example is here (I have them same thing in v8 and v9):
