<suffix> Suffix

Qualifiers that follow a person’s name (for example, Sr., Jr., III, 3rd).

Usage/Remarks

Best Practice

The <suffix> element should be used for parts of people’s names, not for degrees, such as Ph.D. or DDS. The academic degrees are part of the information that is known about a contributor, but not part of the name of the contributor. Academic degrees should take the <degrees> element. Degree and certification information may be placed directly following the person’s name within the contributor information: 
<contrib contrib-type="..." corresp="yes">
  <name>
    <surname>Smyth-Jones</surname>
    <given-names>George</given-names>
    <suffix>Sr.</suffix>
  </name>
  <degrees>PhD</degrees>
</contrib>
Another valid style is to include the <degrees> later within the <contrib> element, interspersed with other types of contributor information such as <address>, <aff>, <bio>, and <email>.
