BluePrint: Data List

Introduction

In many cases, the representation of data in a table visually dissolves the structure of the information, and is therefore difficult to consume for user:

An alternative concept is to represent records as a list of cards with a context-adapted per-item design (typically nested DIVs which allow various styling options):

The most commonly known example for this concept is certainly the facebook-timeline, but many other websites have adopted this concept as well:

Currently, Sahana-Eden lacks a framework for these data lists - whereas there is a fairly complete framework for data tables. This BluePrint is for a datatables-equivalent framework for data lists.
