The one-dimensional view, a far cry from the 3-dimensional view that is one of the targets of the AllPeople project, is quite simply a list view of the experiences that have been shared and to which you have access.
In this list view you see very simplistic overviews of the media deposited in the experiences, but you also have the title and part of the description.
This is an effective view for the results of any filters you may have set.
