Subject: RE: [grouper-users] Grouper 1.6.1 UI membership list sorting

* Consolidation and de-duplication - Grouper would be caching data from 
multiple sources, but presenting a consolidated set. Should subjects 
from different sources which represent the same person be consolidated 
into a single subject? now? ever?

I was thinking of only caching data for people in Grouper.  i.e. search for a 
subject in a group, or show the members of a group.  Not a general subject 
search (though for a second phase I guess this isn't out of the question).  
This is the grouper_members table.  You still have however many sources you 
had before, so if you have duplicates across sources, that is not Grouper's 
problem


* Timeliness - how up-to-date would the local Grouper subject store need 
to be? In our case if would be unacceptable if it were out-of-date by 
more than a few seconds

Grouper does not need to display that information, just search/sort on it.  
So Grouper could still go to the source when displaying information about the 
user (and maybe fall back if the subject is not resolvable).

Thanks,
Chris
