Contributor Group

Container element for information concerning a grouping of contributors, such as primary authors, editors, sponsors, translators, illustrators, etc. The members of the group are contributors who worked individually, not as a group.


The @content-type attribute should be used to name the type of contributor, “authors”, “editors”, “translators”, etc.

The <contrib-group>, should not be confused with the element <collab>, which is used for groups of authors, editors, etc. who are credited under a single name, either as a collaboration in the strictest sense, or when an organization, institution, or corporation is given as a contributor.

If issue contributors (as opposed to contributors to a particular article), are part of the metadata for an article, they should be listed in a separate <contrib-group> with a @content-type attribute such as “issue-editors”.

Related Elements

This element is for grouping individual contributors in the metadata of an article. The <person-group> element performs a similar function of grouping individual contributors, such as authors and editors, within a bibliographic reference (<element-citation> or <mixed-citation>).

The element <collab> is used where the individuals are not the contributors, the contribution was made by the group as a whole, for example a report which has a laboratory or department as the official author.
