I have a short teaser text under the headline of my news article and I wanted to ask, if I could use the property 'abstract' for it, which is a property of the type 'CreativeWork'. In the Documentation of 'NewsArticle' it says, that I can use properties of type 'CreativeWork' https://schema.org/NewsArticle. But when I read the description of the 'abstract' property it says : "An abstract is a short description that summarizes a CreativeWork." https://schema.org/abstract. So I was not sure, if I could use this property for 'NewsArticle' or not.
The inheritance hierarchy up to NewsArticle, as per https://schema.org/NewsArticle, is
Therefore all properties of CreativeWork are available in Article, and all properties of Article are available in NewsArticle.
https://schema.org/abstract says
Used on these types
- CreativeWork
https://schema.org/CreativeWork#subtypes lists Article as a subtype
