Revit User Group Sydney

I've been looking for some ways to read and write data to families directly - the RFA files, not the RVT files.

I am trying to build a database catalog of several hundred (maybe thousands) families so I can extract data, write data, and create QA checklists.

Is there a simple way to do this, or is it a job for the API?

I have been looking at an addon called Revit Family Manager from http://familit.com/ - has anyone had any experience with this app?
