Structure: Collections and Views

• Proposed assertions (subject to review)
• Collections must always appear in the context of a view
• Each collection can be viewed in a number of different view types depending on what kind of collection it is and what kinds of items it has (ie. calendar)
• Some view settings are specific to a collection and some span all collections or all collections within a collection type

• Use cases for Sharing Collections and Views
• Show and tell, I want to send you a collection or item and walk you through it. In this use case, users will want the Share to look as identical as possible for both Sharer and Sharee.
  • Mitch and Esther want to review the OSAF events calendar together.
• Here's data for you to be aware of and play around with. In this situation, users don't really care to have the same view settings and in fact each member of the Share would prefer to have their own view settings.
  • A travelling salesman sends his travel calendar to his personal assistant so she can book his flights.
• How do we reconcile these two use cases? Proposal: We allow a one-time sharing of view settings and an advanced menu option to re-Sync view settings.

Quick brainstorm about elements of a view that might persist between sessions

* When do users need the option to customize a view setting for a particular collection? Is that a Canoga feature? **We don't want Sharer's view settings to override the Sharee's view settings if it's a view setting that will affect all collections or all collections of a particular type.
