Simply describe the outcome of the change. This should be non-technical and accessible to a casual community member.
A short (~200 word) description of the change, the abstract should clearly describe the change. This is what will be done if it is implemented, not why it should be done or how it will be done.
The technical specification overview should outline the public API of the changes. That is, changes to any of the interfaces Nouns currently exposes or the creation of new ones. Clearly describe how the specification should be implemented.
Link to the implementation and test cases for review.
