Code List 81 - 16: Additional text not part of main content

Explanation

Code 16 indicates a publication contains supplementary text content, such as tests, sidebars, and articles.

This code is always set in a <ProductContentType> element for digital publications, since supplementary content, by definition, is not the primary source of information.

Only for use in ONIX 3.0 or later.

Schema.org mapping

Code 16 is the equivalent of setting a textual access mode using schema.org metadata.
