The structure type http://webmaster.yandex.ru/vocabularies/enc-article.xml may contain the following properties:

  • title — heading of the article.

  • content — text of the article.

  • category — category or topic. One article may belong to several categories.

  • references — list of references, links, etc.

  • author — author: name, academic title, or other distinguishments;

  • source — source;

  • source-date — date of publication (in the specified source and/or by the specified author, but not on the website where the encyclopedia or dictionary is published).

  • photo — images. There may be several images.

Note. 

In most cases, the value of the property is the text contained within the HTML element marked with the itemprop attribute. Some elements are exceptions to the above rule:

  • Element <meta>: the value of this property is the value of the content attribute (thus, in the above example the structure contains two different entries for the category property with the values “Children's literature” and “Soviet authors”).

  • Element <img>: the value of this property is the value of the src attribute (in the above example, the value of the photo property is the link to the image).

  • Element <а>: the value of this property is the value of the href attribute.

For a full list of exceptions, please refer to the microdata specification.
