Linked Art API: Statement Structure

Table of Contents

Introduction

Statements are a human-readable expression of the content or note about the entity being referred to. Even if there are structured forms of the resources, these textual descriptions are useful to render to end users. They can have both internationalized content, as well as internationalized labels in the form of Name instances associated with them. These statements are embedded within the resource being described, rather than separate long form texts.

Statements are described in the base patterns of the model documentation, and examples are present for practically every class.
