[Zope3-Users] how to catalog principal annotations?

[Dominique Lederer]

hi

I have users residing in an external database.I store user data with
principal annotations. Now i want to create a view where users with a
special annotation are listed.

Is it possible to catalog principal annotations and how?
Or do i have to create a special Person Class where all principal data
is stored on, and connect it somehow to Principals?

thanks for your help
