The risks of upsetting people or infringing their copyright by storing, publishing or distributing other people's copyright materials increases along this axis.
The further down this line you publish the greater the risk of upsetting someone or even infringing their copyright. HOWEVER, this is a general schematic to emphasize 'risk'; of course a copyright owner could question your use of their work anywhere along the axis - user beware - re-user be even more aware!!!
It's OK to store copies of materials if it's for personal study: this applies to pupils, teachers and others in the workforce - and families and members of the community - everyone.
It's OK to share some things because some of the Exceptions allow it. For more on this please see the School and Copyright section
It is also OK to store and make availible a lot of materials within the school because they are covered by the Terms and Conditions that accompany some e-learning resources. It's OK to store and share some things like broadcast programmes and recorded music if the school has the ERA licence and a PRS one.
NOTE. This is describing the sharing of exisitng materials not re-using them or altering them.
As usual nothing's easy and different resources have different Terms and Conditons so while some say it's OK to share them only in the school premises, others will allow use through a VLE as well - and some may allow use outside of school if its clearly non-commercial. For instance it is OK to use Audio Network music throughout the school and in a VLE because the licence provides the permission, but it is not OK to distribute their music files outside the school or across the internet.
Bad News. Unfortunately there's no easy answer or general rule - each resource or type of activity has it's own rules.
