As a cataloger, I want the option to edit either the Work entity or the Instance entity while in edit mode. Further it doesn’t matter whether the edit mode ‘opened’ to the Work or the Instance. I should be able to edit components for either entity.

In scope

• Editing an existing Work

• Editing an existing Instance

Out of scope

• Action buttons

• Multiple instances associated with a Work

• Cloning a Work or Instance

• Adding a new Work or Instance

Use cases

1. Start in edit mode - Work entity only one instance

2. Work entity → toggle to edit single Instance entity

3. Start in edit mode Instance - Instance entity

4. Instance entity → toggle to edit Work entity
