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”.
This element joins the related element <on-behalf-of> in describing the contribution of a contributor. The <role> element will say that a person is an “Editor” or “Associate Editor”, and the <on-behalf-of> element will state that this editing was undertaken as a representative of a group or organization:
<on-behalf-of>for the Multiple Sclerosis Collaborative Research Group</on-behalf-of>
While not considered best practice, it is also acceptable to tag the example as:
<contrib> <name><surname>Campion</surname> <given-names>M</given-names> </name> <role>for the Multiple Sclerosis Collaborative Research Group</role> </contrib>
<!ELEMENT role (#PCDATA %role-elements;)* >
