[Zope3-dev] Principal with annotations

[Florian Lindner]

Hello,
I've asked this questions to the list already some time before but the 
discussion didn't led to a solution for me. So I try again...  ;-)

I want to create a principal which just works like the normal principal 
but addionally store some information related to it, for example real 
name, email adress, homepage, ... Later the principal should also be 
able to store more complex information, for example lists of references 
to other prinicpals.

What's the best point to start? I don't expect a step-by-step howto 
hiere (also I would like it ;-)) but I need a point to start. Should I 
build a new interface based on ISimplePrincipal and enhance it or use 
PrincipalAnnotation utitlity (how to do that?)?

Thanks for help,
Florian
