Explanation

Code 17 is used to indicate a publication contains promotional material for other works, typically by the same author or in the same series.

This code is always set in a <ProductContentType> element for digital publications, since promotional content, by definition, is never an essential source of information.

Only for use in ONIX 3.0 or later.

Schema.org mapping

There is no equivalent to this value in schema.org metadata as the access modes of the content do not take into account content that is not required to understand the publication.
