# Assignables

A framework that contains wrappers for a PDF to allow creation of an assessment and student work on that assessment.

## Overview

Overview An AssignableDocument is a document that contains a base PDF and stores added markup, annotations, questions, and scoring options for that PDF. This framework focuses on the student and teacher experience. Teachers can assign the document to a student by creating an AssignedWorkDocument from the AssignableDocument. In addition to those data types, Assignables also provides SwiftUI view classes to enable editing of those documents in your own views. Once a student completes their work, they can return it to the teacher to be scored and to receive comments on their work. Authorship is important at each of these steps, so Assignables supports attribution of changes to any document using types that conform to UserIdentity. Since teachers may collaborate on making an assignable or scoring student works, or students might collaborate on a document, both document types support merging copies of the document with any other copy of the same document.
