Rationale

At Zostera, we tried some different approaches to store attributes for our records. While existing solutions using a Unit, Attribute and ObjectAttribute models did work, they resulted in performance issues while retrieving big lists with a lot of attributes.

This project is basically some nice syntax around the idea outlined in this blogpost.
