Annotation Framework Structure

There have been discussions related to two approaches to creating the NSDL Annotation Framework(s). 

1. One uses an all-in-one approach where a single framework is used to define all possible annotation types and allows multiple pieces of annotation data about a resource to live in the same annotation object.
2. The other uses a single individual framework to define each annotation type. 

Examples of both approaches and a summary of the benefits of each are available in a slide presentation within the Conceptual Framework documentation.  Jump to slide 33 to see the annotation related slides.
