One Grouping to Rule them all

This is a work in progress. It is intended to summarize the work of the Display Set Working Group to date.

Overview

The existing approaches of collecting resources, Admin Sets and User Collections, are not adequate for the broad set of use cases expressed in the community. The Display Sets Working Group has been exploring an approach that will expand the functionality available to applications for grouping resources.

A Vision of One Grouping to Rule them all

Things that make grouping difficult.

As seen in the requirements chart above, there are characteristics of groupings that may not be compatible.
This is further complicated by the fact that some apps may want more than one set of characteristics for their groupings, e.g. sometimes those of an Admin Set and sometimes those of a Display Set.

It is incredibly challenging to have 3 distinct type of groups play nicely together. What would it be like to have one and only one type of grouping that is configurable?

So you love admin sets and don't care about anything else...

AdminSet Configuration:

	Sitewide Setting	Comments
multiple membership within type	OFF
nestable	OFF
browsable	OFF
branded landing page	OFF
ability controls	ON
creators	Select users \| groups	selected users/groups can create new sets of this type AND serve as default manager
managers can...	edit set metadata set participants set release and visibility edit work metadata of all works in set add/remove files of all works in set add works to set	automatically includes CREATOR; specific users/groups that fills each ability role is defined per set
depositors can...	add works to set	automatically includes CREATOR; specific users/groups that fills each ability role is defined per set
viewers can...	view works in set regardless of visibility	automatically includes CREATOR; specific users/groups that fills each ability role is defined per set
workflow controls	ON	workflow is identified per set
APO controls	ON	visibility/discoverability is defined per set

You want to control everything in admin sets and use display sets as exhibits

Create two collection types:

AdminSet type collection with configuration same as above.
DisplaySet type collection with configuration below.

DisplaySet Configuration:

		Can be overridden for specific set?
multiple membership within type	ON	YES	It would be uncommon for an exhibit to claim ownership of its works and not allow them to be in other exhibits. This would also prevent you from adding an existing work that is already part of another exhibit.
nestable	ON	YES
browsable	ON	YES
branded landing page	ON	YES
ability controls	ON		selected users/groups can create new sets of this type AND serve as default manager
creators	Select users \| groups		selected users/groups can create new sets of this type
managers can...	edit set metadata set participants set release and visibility edit work metadata of all works in set add/remove files of all works in set add works to set		automatically includes CREATOR
depositors can...	add works to set		automatically includes CREATOR
viewers can...	view works in set regardless of visibility		can only view based on visibility of the works
workflow controls	OFF		the work has to already exist and by definition be part of an admin set
APO controls	OFF		the work has to already exist and by definition be part of an admin set

You have a self-deposit system and want users to be able to organize their deposited materials

UserCollection Configuration:


multiple membership within type	OFF \| ON	optional (current behavior is ON)
nestable	OFF \| ON	optional (current behavior is OFF)
browsable	OFF
branded landing page	OFF
ability controls	ON
creators	ALL USERS	selected users/groups can create new sets of this type AND serve as default manager
