Article ۰ Element

Elements are self-contained objects that represent structured data that is usually too complex to fit into our usual workhorse which is the Body.

Elements can appear in multiple places within the Article:

  1. Article.elements

Elements of the article which are not part of the textual body, e.g. author, opener and teaser. Those elements should be used to render the article as a teaser e.g. on section pages.

  1. BodyNode.children:

Is the place where Element are quite commonly used. They come in various types and will be rendered inplace, thus breaking up the textual body.

  1. Elements.children:

Some more sophisticated Elements make use of nesting to make their API representation more concise and help to structure things hierarchically:

  • video uses nesting to model its optional poster image which itself is a normal image.

  • galleries have their individual images nested within.

Different types of elements like images or videos share the same message structure distinguished by the ElementType field.

See Sample section.
