Yes, thank you John. That certainly opens up some possibilities. tejay

You have one piece of information, HIPAA related. So data gets tagged for insurance, doctors, and nurses lets say. But along comes a researcher who wants to do data mining on medical records. Some users may consent, others may not. Those who consent can get their data tagged for insurance, doctors, nurses, and researchers. And if we want to get more detailed, maybe there's different types of research going on. Perhaps researcher1 is looking at heart conditions relative to ancestry whereas researcher2 is looking at diabetes in relation to income. A person may consent to one, but not the other, and then have their data tagged for researcher1, but not necessarily researcher2. Hope this example sheds some light on the possibilities with this visibility design.

When is it more useful than row or column level? Is it useful with regards to analytics or machine learning, or only for row by row manual access? I'd really appreciate any examples of where it is used in an unclassified domain (perhaps medical?) Thanks, Tejay
