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