Re: [Bodington-developers] Quotas Implementation

[Selwyn L. <sel...@ph...>]

Matthew:

have you guys locked down the amount of user accounts or special groups 
a user might create...
assuming you have single log on or admin created users... being intranet 
so probably easy... so probably yes [shut up sel]
i.e. to stop what i did in the early days of yahoo to get more space 
[multiple user identities]
not so for a lifelong learning portal unless we do some kind of identity 
creation and identity locking

with our ionode based e-portfolio / learner portals [eells, 
learningmatrix, icebox, pdp4life] we are currently looking at various 
theoretical quota use cases for lifelong learning scenarios...
so this topic is food for thought for us too [currently we set 20mb per 
user until told otherwise]

Once projected scenario is when a student leaves they are given a 
deadline to move their files / electronic stuff so there is room for the 
next batch of students [bear with me :)]

Keeping this to one consideration with multiple theoretical use cases in 
bodington...

"get / set quota expiry date"

our special groups/ communities/ users/  would also have 'quotas'... 
they may like the idea of the group managing a quota, and the user 
managing their individual quota...

are you suggesting you might quota the files uploaded as a total across 
multiple resources against a single user?

Cheers
