The publishingPrinciples property indicates (typically via
URL) a document describing the editorial principles of an
Organization (or individual, e.g. a
Person writing a blog) that relate to their activities as a publisher, e.g. ethics or diversity policies. When applied to a
CreativeWork (e.g.
NewsArticle) the principles are those of the party primarily responsible for the creation of the
CreativeWork.
While such policies are most typically expressed in natural language, sometimes related information (e.g. indicating a
funder) can be expressed using schema.org terminology.
