+        <h3>Data First Approaches</h3>
+        <p>
+Many physical credentials in use today, such as government identification
+cards, have poor accessibility characteristics. Some of these poor
+characteristics include, but are not limited to, small print,
+reliance on small, high resolution images, and no affordances for people with
+vision disabilities.
+        </p>
+        <p>
+When utilizing this data model to create verifiable credentials, it is
+suggested that data model designers use a "data first" approach. For example,
+given the choice of using data or a graphical image to depict a credential,
+a designer should choose to express every element of the image,
+such as the name of an institution or the professional credential, in a
+machine readable way rather than solely relying on the image to convey this
+information. This approach is preferred because a "data first" approach
+provides the foundational elements of building different interfaces for
+people with disabilities.
