The title or role of a contributor (such as an author) to a work, for example, “Editor-in-Chief”, “Contributor”, “Chief Scientist”, “Photographer”, “Research Associate”, etc.
Information on the role or type of contribution is collected in two places: in the @contrib-type attribute on the <contrib> element, and in the <role> element (which is part of the contributor information inside a <contrib> element). For example, the <contrib> element’s @contrib-type attribute might have a value of “editor”, whereas the content of the <role> element could be “Associate Editor”. As another example, the <contrib> element’s @contrib-type attribute might be “author”, and the <role> element might contain “Principal Author”.
